Definitions

  • the application relates to an elongated cladding profile pressed from a mixture of fibers and a binder, provided on one longitudinal edge with a groove and on the other longitudinal edge with a tongue profile, in particular for cladding building facades.
  • the chip or fibrous mixture can be, for example, a non-rising mixture of comminuted lignocellulosic particles, such as comminuted and dried wood shavings, bagasse fibers and the like.
  • Act., act which is a thermosetting binder based on thermoset, such as a melamine - urea formaldehyde or phenol formaldehyde resin, is admixed.
  • thermoset such as a melamine - urea formaldehyde or phenol formaldehyde resin
  • fibers of other materials such as glass fibers, rock wool or asbestos fibers, alone or several of them mixed with one another, to which appropriate, preferably organic, binders have been added can also be used.
  • Profile bodies such as table tops, window sills, pallets and the like can be produced from such a mixture in such a way that the non-rising mixture, depending on the shape or desired properties of the finished profile body is filled into a lower press part either in a layer thickness that is as uniformly thick as possible or deliberately different at certain points.
  • the layer thickness of the mixture in the lower press part is usually four to seven times the finished profile body.
  • the press is a pre-press
  • the mixture filled into the lower part of the press is pre-pressed there by moving in a press ram (upper part of the press) and almost compressed to its final dimensions.
  • the strength of the preform thus produced is sufficient to prevent it from deforming or breaking when it is removed from the prepress. It is then placed, possibly under simultaneous covering with a covering layer, in a hot press, where the pre-compact obtains its final shape under the action of pressure and heat, thereby curing and possibly being simultaneously covered with a covering layer.
  • the known cladding profiles have proven themselves on a large scale, but they can still be improved depending on the intended use and location. If horizontally installed outer wall claddings are produced from the known cladding profiles, then there are trough-shaped depressions in which moisture, dirt and the like can be deposited in unfavorable climates or unfavorable weather conditions and can cause premature wear.
  • a cladding profile for buildings which is pressed from a mixture of fibers and binders, is known (EP-A-0 082 887), the surface of which is provided at regular intervals with grooves running parallel to the width of the cladding profile. So that the cladding profile is straight and level, counter grooves are arranged on its back, which are parallel and symmetrical to both sides of the groove projected onto the back.
  • a press mold for the production of cured molded articles from the same mixture is also known (DE-A-1 198 994), with which a groove is to be produced simultaneously in one end face during pressing.
  • the mold is provided with a spring-loaded, vertically movable side stamp.
  • the invention is therefore based on the object of providing a cladding profile which is predominantly smooth and level, which can be laid in a simple manner in the manner of a slip formwork and on which parts which are particularly stressed mechanically and in terms of climate are also designed to be correspondingly resistant.
  • the cladding profile has a wall thickness that increases substantially continuously from one to the other longitudinal edge, has a higher density on the longitudinal edge with the greater wall thickness than on the longitudinal edge with the smaller wall thickness and at least on that after installation visible surface is provided with a firmly adhering protective layer.
  • the increasing wall thickness of the cladding profile allows easy horizontal laying in the form of the slip formwork. Since the longitudinal edge, which has a greater wall thickness, has a higher density, it is particularly resistant to unfavorable climatic and mechanical loads in combination with the firmly adhering weather-resistant protective layer.
  • a device For the production of the cladding profile, a device has proven to be advantageous with a pre-press, consisting of a press lower part with a bottom that slopes obliquely from the inside out and a lowerable frame surrounding it and forming a box with it, and a press upper part, the part of which presses toward the press lower part Surface is also inclined from the inside to the outside and is provided with a thickening on the outer edge, and a hot press, consisting of a press lower part with a bottom extending from the outside inwards and a thickening on the outer edge and a press upper part with in the same way as the bottom of the lower press part of the press surface.
  • the device can be designed for the production of a single elongated cladding profile. However, it is more advantageous if it is designed for the simultaneous production of two cladding profiles, ie consists of a double pre - press and a double hot press, which are composed of the mirror image arrangement of two pre and hot presses.
  • the cladding profile is produced by first filling the mixture into the lower press part of the pre-press in such a way that it forms a flat surface, and then lowering the upper press part and thereby compressing the mixture almost to its final density, so that the pre-compact is then made removed from the pre-press and, after rotating through 180 degrees about its longitudinal axis, placed in the lower press part of the hot press, the protective layer is placed on its surface and, after lowering the upper press part of the hot press and applying heat, it is pressed.
  • the cladding profile 1 has such a shape that the wall thickness at the lower longitudinal edge 2 in FIG. 1 is greater than at the - in FIG. 1 upper - longitudinal edge 3 of the cladding profile 1.
  • the lower longitudinal edge 2 has an undercut and a groove into which the cross-sectionally nose-shaped edge 4 of the upper longitudinal edge 3 is immersed in the installed cladding profiles.
  • a larger number of fastening holes are provided on the upper longitudinal edge 3.
  • the cladding profiles are on a base, for. B. a house wall or battens attached to the house wall. Since the longitudinal edges 2 and 3 are loaded more than the remaining volume of the cladding profile, the cladding profile there should have a higher compression than the remaining volume of the cladding profile.
  • the lower part of the pre-press shown in FIG. 2 has a fixed middle part 5 and a frame 6 surrounding it, which is designed to be raised and lowered by a certain distance.
  • the position of the frame 6 shown in FIG. 2 corresponds to the non-lowered state.
  • Middle part 5 and frame 6 form a filling space into which the mixture to be pressed is filled up to the flat line 7.
  • the bottom 8 formed by the surface of the middle part 5 has an oblique course, so that the filling space on the left edge is able to hold a larger amount of the mixture than in the middle.
  • the preliminary press according to FIGS. 2 and 3 and the hot press according to FIG. 4 are designed in such a way that two cladding profiles can be pressed simultaneously. If individual cladding profiles were to be pressed with the press, then only half of the middle part would be required.
  • the filling space is filled with the mixture and the upper press part 9 is attached.
  • the surface of the press upper part 9 facing the filling space is provided with a thickening 10 on the outer edge on the frame 6 - this is where the cladding profile is to be given a higher compression. If a vertical force is now exerted on the upper press part 9, then it moves down together with the frame 6 until the frame 6 is seated on the supports 17. In the process, the mixture is compressed, and in fact much more strongly at the outer edges than in the middle, because a larger amount of the mixture was present in the region of the outer edges and because of the thickening 10.
  • the frame 6 and the upper press part 9 are brought back into the position shown in FIG. 3.
  • the pre-compact is removed from the pre-press, rotated by 180 degrees about its longitudinal axis and placed in a hot press.
  • the hot press with the upper press part 11 and the lower press part 12 is shown in the closed state in FIG. 4.
  • at least one primer film is placed on its inner and outer surface, which flows during hot pressing and connects firmly to the cladding profile.
  • the left end of the hot press is shown more clearly in FIG. 5 than in FIG. 4. It should be particularly pointed out that the upper press part 11 has a recess 18 on the left edge 13 and the lower press part 12 is provided with a thickening 15 near the left edge 14. Both mutually support each other in such a way that the prepress is held in place and the firm connection of protective layer and preform is guaranteed.
  • the part 16 which is outlined in dash-dot lines, is removed by profile milling at the higher compressed lower edge 2 of the cladding profile.
