    The invention relates to a device for producing a supply roll of a compressed sealing strip of an open-pored, covered on one side with a self-adhesive cover sheet foam tape with a winding core for the supply roll receiving winding mandrel, with a support roller for the pressure on the winding mandrel roll of the supply roll and with one of the support roller upstream feeder for the foam tape.
    In order to compress sealing strips of an elastically compressible, open-cell foam and to wind supply rolls, it is known (DE 24 10 121 A1) to laminate a foam tape on one side with a cover sheet and wound with the laminated cover sheet under a tensile load on a winding core wherein the tensile load of the cover sheet on the outside of the winding provides for a radial pressure component between the winding core and the cover sheet. The finished supply roll is then wound several times to secure with an excess length of the cover sheet. A particular disadvantage is that the tensile load leads to an elastic elongation of the cover film, so that when using a compressed in this way sealing tape, the provision of the elastic strain must be considered.
    An expansion of a compressible foam tape with laminated cover sheet is avoided in another known winding device for producing supply rolls of compressed tape (DE 26 47 942 A1) characterized in that the winding core of the supply roll against a stationary mounted, driven support roller is guided during the winding process radially so in that the smallest gap between the support roller and the already formed winding ensures a corresponding compression of the foam tape. Because of the lack of a larger tension, however, the achievable compression of the foam tape remains limited in the supply roll.
    The invention is therefore based on the object, an apparatus for producing a supply roll of a compressed sealing strip of an elastically compressible, open-cell foam tape, which is covered on one side with a self-adhesive cover film, so that the laminated cover sheet none of the use of the sealing tape impairing strain is exposed without having to do without a comparatively high compression of the sealing strip in the supply roll.
    Based on a device of the type described, the invention solves the problem set by the fact that the support roller on the feed side of the winding core is associated with a pressure roller, that the narrowest gap between the support roller and the pressure roller a common guide for the incoming from the feeder, on one side a self-adhesive layer with a removable protective cover having foam tape and on the other hand for withdrawn from a take-off roll, on the side facing away from the self-adhesive layer supplied, self-adhesive cover sheet and that are provided for the protective covers of the self-adhesive layer and the self-adhesive cover sheet take-up rolls.
    Since, according to these measures, the foam tape provided with a self-adhesive layer is compressed between the support roller and the pressure roller and at the same time is laminated on the side opposite the self-adhesive layer to the cover film, during the compression of the foam tape on the cover film, only a compressive force supporting the lamination on the foam tape, but no traction exerted. During the short guidance of the compressed foam tape to the winding of the supply roll along the support roller, the cover sheet remains substantially free of tension, wherein the foam tape can hardly relax within the deflection between the pressure roller and the winding of the supply roll along the support roller. The foam tape can thus be supplied in compressed form to the winding forming on the winding core of the supply roll. By pressing the coil to the support roller, the foam tape is optionally pressed under a re-compaction to the respective outer winding winding, wherein the abutting turns on the free after removal of the protective cover self-adhesive layer of the foam tape and the cover sheet in the tape longitudinal direction sufficient shear-resistant compound received to prevent mutual sliding of the adjacent turns of the roll required for elastic recovery of the compression, without preventing detachment of this adhesive bond during unwinding of the supply roll. This means that due to the shear-resistant connection of the adjacent turns, the compression of the sealing strip within the roll is maintained via the cover sheet, even if an outer covering is missing. The tensile stresses occurring within the cover sheet due to the radially acting elastic restoring forces of the compressed foam tape remain limited and can be absorbed by the cover sheet without risk of undue stretching.
    Particularly advantageous construction conditions arise when the unwinding roll for the self-adhesive cover sheet is provided on the side facing the support roller of the foam tape, wherein the take-up roll for the protective cover of the self-adhesive cover sheet whose take-off roll and the take-up roll for the protective cover of the self-adhesive layer of the pressure roller are arranged downstream. In this case, namely, the cover sheet in the deflection region between the pressure roller and the forming roll of the supply roll can be performed without stress on the support roller fitting, because the elastic restoring forces of the compressed foam tape act radially outward.
    Although different constructive solutions are possible for the relative to the stationary mounted support roller radial guidance of the winding mandrel, an embodiment of the preference is given, which is characterized by the storage of the winding mandrel for the supply roll on a loadable with a Andrückmoment swivel arm. With the help of the swivel arm favorable construction conditions are created, resulting in a simple, dependent on the respective winding diameter control of the pivotal position of the swivel arm by acting on the swivel arm with a predetermined Andrückmoment.
    The foaming belt feeder may include means for applying the self-adhesive layer to the foam tape, which, however, makes the device expensive. To avoid a higher design effort, the foam belt feeder may comprise a take-off roll for the foam tape provided with the self-adhesive layer and the protective cover, so that a suitably prefabricated foam tape can be used.
    In the drawing, the subject invention is shown, for example. Show it
    1 shows a device according to the invention for producing a supply roll of a compressed sealing strip in a schematic side view, and FIG. 2 shows a supply roll produced with the device according to the invention in a schematic, partly torn-off side view on a larger scale.
    An apparatus for producing a supply roll 1 of a compressed sealing strip 2 has a driven mandrel 3 which is mounted in a pivot arm 4 and receives a winding core 5 for the winding 6 forming the winding tape 2 during winding. The winding 6 is pressed via the pivot arm 4 to a stationary in a frame 7 support roller 8. For this purpose, the swivel arm 4 is acted upon with an adjustable contact pressure or controlled with respect to its pivot angle relative to the support roller 8. The support roller 8 cooperates with a roller 6 upstream of the pressure roller 9, which is guided in the radial direction relative to the support roller 8 displaceable in the frame 7, which is indicated by a slot guide 10. This pressure roller 8 can either be subjected to a predetermined pressing force or with respect to the width of the narrowest gap between the support roller 8 and the pressure roller 9 is turned is. In the narrowest gap between the support roller 8 and the pressure roller 9, a provided for producing the supply roll 1, open-pore and elastically compressible foam tape 11 is compressed and coated with a self-adhesive cover sheet 12 at the same time. The feed device 13 for the expanded foam strip 11, which has a self-adhesive coating 15 provided with a protective cover 14, is formed by an unwinding roll 16, from which the foam tape 11 is drawn off via the driven support and pressure rollers 8, 9. For the cover sheet 12, a take-off roll 17 is also mounted in the frame 7, wherein the adhesive layer 18 of the self-adhesive cover sheet 12 is provided on the outside of the winding. The protective cover 19 of this adhesive layer 18 is withdrawn from the cover sheet via a driven take-up roll 20, so that the cover sheet 12, which is drawn on the side of the support roller 8 in the gap between the support roller 8 and the pressure roller 9, during the compression of the foam tape 11 with the adhesive layer 18 is pressed against the foam tape 11, on the self-adhesive layer 15 of the foam tape 11 opposite hinge side.
    The protective cover 14 of the self-adhesive layer 15 of the on the side of the pressure roller 9 supplied foam tape 11 is withdrawn on the exit side of the pressure roller 9 by means of a driven take-up roller 21 of the self-adhesive layer 15, thus on the outside of the compressed, along the support roller 8 between the pressure roller 9 and the winding 6 deflected foam tape 11 comes to rest with the effect that the winding 6 supplied tape portion adheres to the cover sheet 12 located on the Windungsaußenseite. If the winding 6 has grown to a size provided for a supply roll 1, the pivoting arm 4 is pivoted away from the support roll 8 and the foam tape 11 is severed together with the cover film 12 in order to be able to deduct the finished supply roll 1 from the winding mandrel 3.
    2, the finished supply roll is shown. The partially withdrawn from the supply roll 1 and elastically recovered in the region of the withdrawn length sealing strip 2 is provided on one side of the foam tape 11 with the self-adhesive layer 15 and on the opposite side with the laminated cover sheet 12, in terms of their adhesion properties in combination is formed with the self-adhesive layer 15 so that a releasable adhesion is achieved. In the supply roll 1, the self-adhesive layer 15 of the individual turns is adhesively bonded to the cover film 12 of the respectively adjacent turns with the effect that displacements in the circumferential direction are prevented between these turns. Since the cover sheet 12 is formed sufficiently tensile strength, the compressed sealing strip 2 is held within the supply roll 1 under a radial compressive stress, which precludes an elastic, expanding provision of the foam tape 11. The sealing strip 1 can therefore be deducted in the respectively required length of the supply roll 1, without the rest of the sealing strip 2 of the supply roll 1 is subject to a return risk.
