A longitudinal groove (3) is provided on the surface and extended in a longitudinal axial direction. The coil sectionally comprises different inclinations.

Description

The present invention relates to a coating agent for applying a material to a substrate, comprising a rotatably storable cylindrical roller.

Such application means in the form of a roller for applying a material to a substrate, in particular for applying liquid to pasty deposits on a substrate, are known from the prior art.

Such coverings may, for example, have many different types of screeds for building any type of indoor and outdoor flooring, for example synthetic resin, plastics, cement, mastic asphalt, and others.

When applying a material to a floor, there is the requirement that the material is distributed uniformly and in a defined layer thickness on the substrate. So that a uniformly thick layer is achieved, one uses a roller with juxtaposed slices, such as those from the DE 202 08 369 U 1 is known.

However, in the distribution of viscous materials, especially PMMA, polyurethane and epoxy resin floors, this roller has adverse properties such as slipping over the mass and poor cleaning properties of the assembled components. These disadvantages are only by high effort to push the roller on the ground, or to work around by a high cleaning effort.

The present invention is therefore based on the object to alleviate at least one of the disadvantages listed above.

Furthermore, the present invention has for its object to provide a contract agent, which allows a complaint-free order and is easy to handle.

A contribution to the solution of at least one of the abovementioned objects is made by a means of order according to the features of claim 1.

Advantageous embodiments and developments of the application agent according to the invention will become apparent from the claims subordinate thereto.

In the context of the present invention, a coating means of the aforementioned type is proposed, which is developed such that the lateral surface of the roller has at least one coil extending inwards in the lateral surface.

The helix causes a quasi-induced, automatic forwarding of the order material on one side, thus the force required for the operator is reduced because not all the excess application material has to be pushed in front of the roller.

In addition, this results in only an overflow track on one side, in the best case on the side where there is still no order material. This allows faster and more efficient work. By turning the roller together with its longitudinal axis, this effect for left and right-handed, so for left and right handed use.

Due to the special shape of the lateral surface, the support surface is raised to the ground and thus the roller rolls off better and does not slip over the ground. On the other hand, it is prevented by the induced sideways conveying the excess application material that the roller runs on the otherwise jammed before the roll material or slip over. Due to such slipping, otherwise the job would become unusable due to the abruptly increasing layer thickness and would have to be repeated.

As a helix in the context of the present invention is understood to mean a curve which winds with a slope around the mantle of a substantially cylindrical body. As a helix in the context of the invention can u.a. Also, a helical structure, a helix, a helix or a substantially cylindrical spiral are understood without departing from the spirit.

A helix extending inwardly in the lateral surface in the sense of the invention can be designed to be continuous or interrupted, and can comprise a groove or the like channel or a groove incorporated in the lateral surface, which has the profile explained above. The cross-sectional shape of the helix is not initially specified. The helix is preferably designed in this way in order to be able to convey and discharge excess application material when unrolling the application medium to one side of the device.

The roller of the application means according to the invention may have on at least one of its end faces a recess for receiving an axle. Such a recess may be designed as a blind hole to receive a stub axle. Both opposite end faces may each have such a blind hole to engage from both sides with a suitable device according to the roll and to be able to roll it on a substrate. Alternatively, the recess can also be designed as a through hole for the passage of an axle. Further possible embodiments are described below.

In an advantageous development, preferably, a pitch of the helix in the areas between 1-100mm, preferably 2-70mm, more preferably 5-15mm, can be realized. Thus, a different, desired sideways promotion of the order material can be achieved. In a sectionally different pitch height you can achieve different sideways conveying speeds of the order material.

In an advantageous embodiment, the helix has a different pitch in sections. Thus, desired conveying effects and an optimal adaptation to the behavior of the order material can be achieved. For example, in the middle region of the roller, more application material will usually be incurred, which has to be conveyed to the side. This can be compensated for with a different pitch of the helix in the middle region of the roll compared to the edge region.

If, according to a further advantageous embodiment, the helix on the left and / or right running, or a combination of both realized, one can influence the sideways promotion of the application material directionally.

In particular, can be realized by arranging one or more coils, from the center of left and right running in the direction of the end faces of the roller, a material delivery on both sides.

By varying the depth of the helix, preferably between 0.5-50 mm, preferably 1-25 mm, particularly preferably 1.5-5 mm, the layer thickness of the application material can be determined.

In a further advantageous embodiment, the depth of the helix is formed differently in sections in the longitudinal axial direction of the roller.

Due to the cross-sectional shape of the or each helix (viewed transversely to the longitudinal axis of the roller), the application and unwinding properties of the roller can be influenced. Here, the shape can be adapted to the substrate and the flow properties of the application material used.

Thus, the helix, as seen in the longitudinal axial direction of the roller, have a continuously constant or changing shape.

In this case, the cross-sectional area of the helix may preferably be semicircular, triangular, trapezoidal, quadrangular, rectangular, oval or formed from a combination of the protruding shapes, or may be formed with a planar bottom and sidewalls extending convexly towards the outside.

The surface area of the negative form of the helix may preferably be in the range of 1-150 mm ² , preferably 1.5-70 mm ² , particularly preferably 2-40 mm ² , and directly influences the application rate of the application material, whereby an adjustment to the viscosity of the Order material can be realized.

In a further advantageous development, it can be provided that at least one longitudinal groove extending in the longitudinal axial direction of the roller is arranged on the lateral surface of the roller. A longitudinal groove is understood to mean a groove in the lateral surface which extends parallel to the longitudinal axis of the roller.

In a further embodiment, a multiplicity of, preferably equidistantly distributed, longitudinal grooves can be applied or incorporated on the lateral surface.

The proposed longitudinal groove or longitudinal grooves can further improve the sideways conveying of the application material and / or increase the quality of the order. In particular, the longitudinal grooves also prevent the roller from floating on the application material. Furthermore, longitudinal grooves increase the Adhesion of the roller to the substrate and prevent unwanted slippage of the roller.

As with the variation of the depth of the helix, one can also influence the layer thickness of the application material with the variation of the depth of proposed longitudinal grooves. The depth of a longitudinal groove may preferably be between 0.5-50 mm, preferably 1-25 mm, particularly preferably 1.5-5 mm.

In a further advantageous embodiment, the depth of a longitudinal groove in the longitudinal axial direction of the roller is formed differently in sections.

The cross-sectional area of a longitudinal groove can be used to influence the application and unwinding properties of the roller so that the shape can be adapted to the substrate and the flow properties of the application material used.

Thus, a longitudinal groove, seen in the longitudinal axial direction of the roller, have a continuously constant or else a changing shape.

In this case, the cross-sectional area of a longitudinal groove may be preferably semicircular, triangular, trapezoidal, quadrangular, rectangular, oval or formed from a combination of the protruding shapes, or may be formed with a planar bottom and sidewalls extending convexly toward the outside.

The surface area of the negative mold of an optional longitudinal groove may preferably be in the range of 1-150 mm ² , preferably 1.5-70 mm ² , more preferably 2-40 mm ² . This value directly influences the order quantity of the application material, whereby an adaptation to the viscosity of the application material can also be realized.

Particularly advantageous is a development of the invention, in which the lateral surface of the roller has outwardly extending pins.

If one attaches a plurality of preferably equidistantly distributed longitudinal grooves on the lateral surface and realizes a suitable, rather small pitch of the helix, one can reduce the distance of the longitudinal grooves to one another so far that as a result between adjacent sections of the helix and a crossing pair of adjacent longitudinal grooves Cones remain standing, which form the surface of the roller. Each pin is thereby circumferentially circumferentially of the roller by a pair of parallel longitudinal grooves and longitudinally bordered by adjacent sections of the helix and spaced from the adjacent pins.

If the distance between adjacent longitudinal grooves and / or the pitch of the helix is further reduced, particularly small journals can be formed, which leave only small imperfections of application material.

The aforementioned cones could also be referred to by the person skilled in the art as pimples, spikes or the like without deviating in any way from the idea on which such embodiments are based.

Advantageous embodiments of the invention, which have the above-mentioned cones on the lateral surface of the roller, show the advantage that when applied a taching effect can be set in the processed application material. By the defined detachment of the pin surface of the application material during unrolling a particularly uniform surface of the material is achieved. Large-area adhesion of the material to the lateral surface of the roller is prevented. The evenly detached material can then flow evenly on the substrate or the floor so that the surface can then be leveled very well. Furthermore, the pins increase the adhesion of the roller to the substrate and prevent unwanted slippage of the roller over the application material.

Furthermore, with embodiments of the invention, which have pins on the lateral surface of the roller, a particularly favorable venting effect in the application material can be achieved. By taking place during rolling of the roller dipping or piercing and the subsequent extraction of the pin in or out of the application material, the application material is aerated and it forms for a short time (immediately after pulling out the pin and before the flow of the material) the peg preformed channels through which air trapped in the application material can escape. Even so, a particularly good and perfect order can be achieved.

A concrete, preferred embodiment comprises a roller having a length of 400-500mm, preferably 450mm. The diameter of the roller can preferably be 50-60 mm, preferably 55 mm. The slope of the helix is preferably 5-9mm, preferably 7mm. The distance between adjacent longitudinal grooves is preferably 6-9mm, preferably 7.5mm. Optional, between adjacent Wendelumläufen and adjacent longitudinal grooves formed pins may have an edge length of preferably 3-4mm and a height of preferably 2-4mm, preferably 3mm.

In a particularly preferred, even further embodiment of the inventive idea, the outwardly directed corners of the pins are further rounded. If an embodiment of the application agent according to the invention is used which has cones on the lateral surface of the roller, the following effect could, if appropriate, be observed with a few special application materials. When rolling the roller in or over the application material outwardly facing corners or side edges of said pin could tend due to their shape and the surface tension of the processed material that "take along" order material or entrain upwards. Thus, the application material could possibly be pulled thread-like from the corners of the pin from the job until the formed thread breaks and the material falls back onto the substrate. The result could be point-shaped imperfections in the job, which may no longer be completely leveled by flowing. The rounding of the pins proposed here prevents such adhesion or favors an early detachment of the application material from the pins and thus favors a particularly uniform and error-free application.

If, according to another embodiment, one or more longitudinal grooves extend parallel to the longitudinal axis of the roll, which are interrupted from end face to end face, the material flow of the application material can be further positively influenced. Alternatively, the longitudinal grooves can also be configured continuously.

Furthermore, it is preferable to design the cross-sectional surfaces of the helix and / or of the longitudinal grooves in such a way that the surface widens in the direction of the outer side of the roll, and preferably widens with a convex, possibly circular curvature. This can result in particularly good rolling properties of the roller. Furthermore, sensitive surfaces are not damaged because the roller has no sharp edges, corners or tips that could touch the ground.

The helix and / or the longitudinal grooves can, according to a further advantageous embodiment, be formed by means of a milling head with a substantially convex cross-sectional area, optionally with a cylindrical lower end. Thus, for example, a helix and / or longitudinal grooves can be produced with a cross-sectional shape discussed in the preceding section.

By introducing a web into one or more longitudinal grooves and / or the helix, in a further advantageous embodiment, a simple wear indicator or a wear indicator is realized in order to recognize when the roller no longer applies the desired thickness of the material. As soon as the web terminates together with the lateral surface of the roller, the user immediately recognizes that the wear limit of the roller has been reached and the desired thickness of the application layer is no longer guaranteed from then on. In this case, the roller must be replaced or reworked if necessary.

In other words, longitudinal grooves and / or the helices may optionally have one or a plurality of interruptions of the longitudinal grooves of lesser depth. These webs can serve as an indication of the state of wear of the roller (namely as wear indicators).

The depth of such wear indicators can, based on the total depth of the longitudinal groove or the helix, preferably in the range of 1-70%, preferably 1-50%, particularly preferably 1-30%, amount.

If the roll is made of aluminum, steel or stainless steel, according to another embodiment, the weight of the roll increases, which assists in clean rolling while at the same time facilitating handling. As a result, the force is further reduced because the roller is not pressed, but only needs to be moved back and forth. The use of such a material also ensures a long life and durability of the roller. Thus, the large amount of work for the production of the roller, which is realized by turning and milling processing relative.

By a possible integral construction of the roller, according to a further advantageous embodiment, there are no cavities in which the application material can deposit. As a result, the roller, if necessary after being soaked in a detergent, can be easily cleaned by rinsing. Here also highly concentrated alkalis and acids, as well as sharp solvents used, provided that the roll was made of one of the above materials.

If the ratio of diameter to width of the roll is preferably carried out in the range between 1: 1-1: 3, preferably 1: 3-1: 5, particularly preferably 1: 5-1: 10, the roll can be used for different requirements To run. For example, narrow rollers are suitable for smaller areas or margins, wide rollers for large areas, and the leveling effect is also supported by wide rollers, since unevenness in the ground can be better compensated.

If the roll is preferably made with a substantially closed shell surface, which prevents the penetration and absorption of processing material, good cleaning properties and efficient use of materials result. In contrast to paint rollers, it should be explicitly pointed out that the roller preferably does not absorb and dispense application material, but merely pushes it in front of it and leaves a certain layer thickness on the substrate.

When the roller is made of a cylinder with a frontal recess, in particular a front concentric, i. centered, bore performs, it can be stored in a simple commercial paint iron. If the roller has cutouts introduced on both sides, in particular holes, it can be stored in a commercially available double-iron strap. Thus, the application agent according to the invention can be used with existing tools and tools.

The diameter of a recess introduced at the end, in particular a bore, may preferably be in the range of 1-90%, preferably 2-50%, particularly preferably 3-30%, of the diameter of the roller.

Alternatively, the roller may comprise a cylindrical tube with a face-mounted disc on one or on each side for mounting in a bracket, wherein in one or both discs recesses, in particular bores, of the type already described may be introduced.

In the present invention, many other embodiments are conceivable, which can be composed arbitrarily of combinations of all features disclosed herein. In this case, in particular, features of the concretely described advantageous embodiments of the application agent according to the invention combine in any way to achieve further advantageous embodiments of the invention.

Further embodiments of the invention, which do not limit the invention to the examples shown, are shown in the drawing and are explained in more detail below. In this case, also generally preferred embodiments and developments of the teaching are explained.

Fig. 1 shows in a perspective, partially schematic view of a first advantageous embodiment of the application means according to the invention with a roller 10. The roller 10 is used for applying a material, such as screed, to a substrate. In the present example, the roll 10 is made by turning and milling of the solid material, preferably of aluminum or steel.

According to the invention, the lateral surface 12 of the roller 10 has a helix 14 extending inwards in the lateral surface 12. The helix 14 is here incorporated as a helical or helical groove or as a channel in the lateral surface 12 of the roller 10 and extends at a constant pitch between the end faces 16, 116 of the roller 10th

For storage or attachment of the roller 10 in a painter hook a recess 18 for receiving an axle (not shown) is incorporated in at least one of the end faces 16, 116. If both end faces 16, 116 have a corresponding recess 18, the roller 10 can also be stored and used in a commercial painting bracket. This is later in Fig. 2 shown.

The inventively provided coil 14 causes a sideways directed conveying the application material on one side of the roller 10, so that less excess application material has to be pushed in front of the roller 10. In addition, this results in only an overflow track of the application material on one side of the roller 10. Slippage of the roller 10 over the ground and a run on the application material are avoided by the coil 14.

Further, the roller 10 of the embodiment according to Fig. 1 on its lateral surface 12 a plurality of equidistant distributed over the circumference of the roller 10 Longitudinal grooves 20 which extend here continuously between the end faces 16, 116 of the roller 10. The longitudinal grooves 20 can further increase the quality of the job. In particular, the longitudinal grooves 20 additionally support the sideways conveying of the application material. Furthermore, during the proper use of the roller 10, they make it difficult to undesirably slide the roller 10 on the ground.

Fig. 2 shows in a perspective, partly schematic view of a second advantageous embodiment of the invention, wherein the roller 10 is mounted ready for use in a painting bracket 22.

In the partially schematic representation of the roller 10, in particular the lateral surface 12, according to FIG. 2 becomes clear that the helix 14 compared with the illustration in FIG. 1 has a much lower slope. Also seen here over the circumference of the roller 10 seen a higher number of equidistantly distributed longitudinal grooves 20 incorporated into the lateral surface 12 of the roller 10.

By incorporating a plurality of longitudinal grooves 20 and the choice of a rather smaller pitch of the coil 14, the distance between adjacent longitudinal grooves 20 and the distance adjacent sections of the coil 14 is so far reduced that in each case between or in the resulting rhomboid intersections of these sections Pins 24 of the roll material remain on the lateral surface 12, which extend on the lateral surface 12 to the outside and in the end form the surface of the roller 10.

In other words, each pin 24 in the circumferential direction of the roller 10 by a pair of parallel and adjacent longitudinal grooves 20 and longitudinally bordered by adjacent juxtaposed portions of the coil 14 and spaced from adjacent pin 24.

Due to the defined detachment of the outside of these pins 24 of the application material during the rolling of the roller 10, a particularly uniform surface of the applied material is achieved. Large-area adhesion of the application material to the lateral surface 12 of the roller 10 is prevented. Furthermore, the adhesion of the roller 10 to the substrate is further improved and it is possible to achieve a venting effect in the application material, which promotes uniform flow of the material after the roller 10 rolls off.

In Fig. 2 Furthermore, in a schematically illustrated enlargement of the circularly marked detail on the lateral surface 12 of the roller 10, details of a pin 24 shown by way of example can be seen. The shape of the pin 24 is formed in this example by the successive milling of the coil 14 and the longitudinal grooves 20, or vice versa. In this embodiment, it is further essential that the outwardly directed corners 26 of the pin 24 are rounded. The proposed rounding of the pins 24 and their corners 26 additionally favors an early and defined detachment of the application material from the pins 24 during the rolling of the roller 10 and thus additionally promotes a particularly uniform and error-free application.

Fig. 3a and Fig. 3b show in a partially schematic representation of the outline of a preferred example of a on the lateral surface 12 of the roller 10 according to Fig. 2 trained, outwardly extending pin 24. Here is - schematically - according to Fig. 3a seen in the longitudinal direction of the roller 10 back and front view of a pin 24 and according to Fig. 3b seen in the circumferential direction of the roller 10 side view of a pin 24 from Fig. 2 shown. In this illustration, it is particularly clear how in this example the pins 24 and their outwardly directed corners 26 are rounded.

Fig. 3c further shows a perspective view of the pin 24 according to Fig. 3a and 3b , This illustration again illustrates the outer rounded shape of the pin 24. Thus, the pin 24 provides the application material virtually no edges at which the application material could be stuck during the rolling of the roller 10. In particular unwanted point-like imperfections in the job can be avoided.

Fig. 4 shows the perspective view of one of the Fig. 3a to 3c alternative embodiment of another exemplary pin 24. Here, the top of the pin 24 is not designed completely round, yet the corners 26 of the pin 24 are rounded in an effective manner.

Fig. 5a shows in a partially schematic representation of a cross section through the coil 14 or a longitudinal groove 20, which in an advantageous manner in the embodiments according to Fig. 1 and or Fig. 2 can be introduced. The illustrated cross-sectional area 28 of the helix 14 or the longitudinal groove 20 is designed to be rectangular in the lower region. This is followed by a flat base of the respective groove at first orthogonally extending side walls 30 at. In the direction the lateral surface 12 of the roller 10 then take these side walls 30 a convexly curved shape. This curvature can, at least in sections, be formed as a circle radius. The side walls 30 terminate, finally, in the lateral surface 12 of the roller 10. Such a curvature of the side walls 30 promotes the rolling properties of the roller 10 and protects the substrate 10 processed with the roller 10, since the lateral surface 12 thus has no sharp edges or transitions.

Fig. 5b shows the schematic representation of a cross section through the lower part of a milling head 32, with a coil 14 or a longitudinal groove 20 from Fig. 5a can be produced. The shape of the cross-sectional area 128 of the milling head 32 corresponds to the already based Fig. 5a described cross-sectional area 28 of the local coil 14 and longitudinal groove 20. With such a milling head 32 can also be in the Fig. 2 to Fig. 4 illustrated embodiments of pin 24 create. In this case, the distance of the pins 24 enclosing helix 14 and / or adjacent longitudinal grooves 20 can be varied. Furthermore, the rounded shape of the pins 24 can be modified by varying the respective groove depth of the helix 14 and / or the longitudinal groove 20.

Fig. 6a shows in a partially schematic representation of a cross section through an alternative embodiment of a coil 14 or a longitudinal groove 20, which optionally also in the embodiments of the roller 10 according to Fig. 1 and or Fig. 2 can be formed. This is followed by a re-planar bottom of the respective groove upwardly extending side walls 30, which directly have a convex curvature, which is formed here as a radius.

Fig. 6b shows the schematic representation of a cross section through the lower part of a milling head 32, with a helix 14 or a longitudinal groove 20 according to Fig. 6a can be produced. Accordingly, the milling head 32 has in its lower portion a continuous convex curved side wall and no cylindrical portion. Even with such a milling head 32 advantageously rounded pin 24 can work out. Again, the pitch of the helix 14, the distance between the longitudinal grooves 20 and the depth of the respective groove can be varied independently of each other. In Fig. 6a has therefore been clearly marked that with a milling head 32 according to Fig. 6b optionally, a pin 24 can be produced, namely depending on the selected Fräsbild. A suitable milling method has already been described. The same basic qualification for training of pin 24, of course, the milling head 32 according to Fig. 5b on.

Fig. 7 Finally, in a partially schematic representation shows a cross section through a helix 14 or a longitudinal groove 20 according to Fig. 6a which additionally has a wear indicator 34. The wear indicator 34 is incorporated as a web with lesser depth in the groove. In other words, the respective groove (whether helix 14 or longitudinal groove 20) has an interruption of lesser depth than the other groove. As soon as due to progressive wear of the lateral surface 12, this interruption or the web on the outer side closes together with the lateral surface 12 of the roller 10, reaching the wear limit of the roller 10 is immediately recognizable.

Of course, a wear indicator 34 in a groove (whether helix 14 or longitudinal groove 20) are incorporated, which according to the example of Fig. 5a or made with any other cross-sectional area.

An application of a desired material can now be realized, for example, as follows with the application agent according to the invention, wherein u.a. the embodiments explained above can be used.

The application material is brought to the bottom by dumping a quantity of the application material. The roller 10, which is mounted in a bracket 22 with or without handle, is placed on the floor. If a handle is mounted in the bracket 22, this allows working while standing. If no handle is mounted, the roller 10 is suitable for working in a sitting or kneeling position edge areas to walls or corners.

The roller 10 is rolled by reciprocating over the floor. The coarsely distributed application material is thus distributed over the entire surface of the floor, since the described formations (in particular helix 14 and / or longitudinal grooves 20 and / or pins 24) of the lateral surface 12 leave a predetermined quantity of the application material on the substrate.

The helix 14 ensures that the application material is conveyed to one side of the roller 10, in the best case on the side where no or too little application material is distributed. This effect also causes not the entire application material has to be pushed in front of the roller 10, but passes the Surplus to one side. This creates only an overflow track. Advantageous formations (in particular helix 14 and / or longitudinal grooves 20 and / or, particularly preferred, pin 24) of the lateral surface 12 also cause a distribution and a daching and venting of the application material. Furthermore, so unevenness of the ground are compensated, since the roller spans by its span recesses of the ground and at these points automatically more application material remains lying, which fills the unevenness. After completion of the work iA cleaning of the roller 10 is generally necessary.

Although the present invention has been described in detail with reference to the illustrated advantageous embodiments, the attached embodiments and the embodiments listed below, it will be understood by those skilled in the art that modifications or modifications may be made by different combinations of particular features or omissions of individual features without departing from the scope of the appended claims to leave. In particular, the scope of the claims should not be limited to the embodiments.
