Definitions
- the present invention relates to a device for dividing a paper web that can be wound on a drum, consisting of a tear tape that is wound helically on the empty drum, thereby dividing the paper web along a helical line. It is known to divide paper webs which are wound on a drum by means of tear tapes which are wound helically on the empty drum, in order to be able to subsequently wind the paper web on an empty spool. Since the tear tapes must have a very high tensile strength, it is known to produce them from paper cords glued together. From EU 727 376 A2 a tear tape is also known, which is formed by a folded, multi-layer paper tape.
- tear tapes made of paper are therefore advantageous because they are recycled at the same time as the paper waste can be.
- these known tear tapes are liable Disadvantage that they ensure the required tensile strength a thickness on the order of at least about 1.5 mm must have. Because such tear tapes on the empty drum be wound helically and over these tear tapes subsequently the paper web is wound up, however, the relatively large thickness of the tear tape that in a variety of layers the paper web wound on the drum through the tear tape Imprints are caused, making this paper meet the requirements quality does not correspond, but rather a committee represents.
- the object of the invention is therefore based on the task To create tear tape, through which this the known tear tapes inherent disadvantage is avoided.
- the tear tape is preferably cut from a film of extruded, pre-stretched polyamide.
- the tear tape is made from a plurality of cords made of polyester fibers.
- the tear tape preferably has a thickness of 0.1 mm to 0.3 mm and a width of 15 mm to 25 mm, preferably of 19 mm.
- the edges of the tear tape are preferably chamfered or rounded.
- a tear tape 1 is shown, which consists of a extruded, pre-stretched polyamide film is cut, making it as can be seen from Fig. 1b, is sharp-edged.
- the thickness d of this tear tape is 0.1 mm to 0.6 mm, preferably 0.1 mm to 0.3 mm.
- the width b of this tear tape 1 is 15 mm to 25 mm, preferably 19 mm.
- the tensile strength of this tear tape 1 is at least 120 kg. The stretch can be a maximum of 8% be.
- a tear tape made from extruded, pre-stretched polyamide is on the one hand sufficiently stiff that it can be applied to an empty drum. It is also sufficiently elastic to fit tightly against the drum. Since it has a very small thickness, only a few layers of the paper web wound over it are provided with embossments, as a result of which the reject that occurs is very small. Since this tear tape 1 is sufficiently tensile, it can fulfill the intended function despite its small thickness, without the risk that it will tear. With different thicknesses of the paper web, tear tapes with different thicknesses can also be used.
- the tear tape 2 shown in FIGS. 2, 2a and 2b is, as can be seen from FIG. 2b, formed with chamfered edges, the edges of the tear tape being chamfered at 45 ° over a third of the thickness d of the tear tape.
- the tear tape 3 shown in FIGS. 3, 3a and 3b is, as can be seen from FIG. 3b, formed with rounded edges, the radius r being equal to half the thickness d.
- Chamfering or rounding off the edges of the tear tapes 2 or 3 is advantageous if the drums on which the paper webs are wound are formed with a soft surface covering which can be damaged by sharp edges of the tear tapes.
- a tear tape 4 is shown, which There is polyester fiber, with a large number of polyester fibers together are processed into cords and individual side by side existing cords 41 glued together to form a flat band are.
- This tear tape 4 can also be between 0.1 mm in thickness d 0.6 mm can be made, providing the required tensile strength has to divide a paper web.
