Definitions

  • the invention relates to an adhesive tape wound on a roll, in particular special wrapping tape for sheathing cables in automobiles, with a textile backing and an adhesive coating on at least one side of the backing.
  • An adhesive tape wound up on a roll and in particular a wrapping tape for wrapping elongate goods is described, for example, in the generic WO 2017/009049 A1.
  • An ultrasonic unit and/or laser unit are provided for this purpose, with the aid of which cut edges are introduced into a carrier.
  • the individual adhesive tapes cut in the longitudinal direction in this way are wound onto a supply unit.
  • the known adhesive tape is equipped with adhesive strips.
  • transverse perforations are provided at this point to facilitate transverse tearing.
  • the known adhesive tape can basically be wound around the cables in the manner of a tubular covering or sheathing as well as spirally around the cables.
  • winding tapes are described, for example, in the further utility model specification DE 20 2018 103 986 U1, which can be traced back to the applicant.
  • a fabric carrier and at least one marker thread introduced into the fabric carrier are provided here.
  • the marking thread positioning when bandaging is particularly intuitive and easy.
  • the marking is used as a positioning aid and the cable wrapped in such a way that a leading winding that is fixed to the cable harness is glued to a subsequent winding with an overlap specified by the positioning aid.
  • the end of the winding glued to the winding has, in practice, an edge running transversely to the longitudinal direction.
  • this can be attributed to the fact that the adhesive tape or winding tape wound onto the roll is made from a textile backing, which as a fabric web is equipped with the required adhesive coating and is then typically cut longitudinally into the individual adhesive tapes. These adhesive tapes are then wound up into rolls and the end of the winding is usually defined with a cut for all adhesive tapes.
  • This cut can be produced, for example, by a rotating knife running transversely to the longitudinal direction, a knife bar or by other cutting devices. Details of the production of such an adhesive tape or winding tape wound on a roll are described, for example, in DE 20 2011 110 445 U1. In addition, reference is made to the applicant's WO 2017/009049 A1.
  • the invention is based on the technical problem of further developing such an adhesive tape wound on a roll in such a way that handling and processing are simplified overall.
  • the invention proposes, in the case of an adhesive tape of the generic type wound on a roll, that the end of the roll glued to the roll has an edge equipped with at least one bevel for haptically easy detachment from the roll.
  • the end of the winding glued to the winding or its edge is equipped with at least one bevel, in contrast to the previous procedures.
  • the procedure can be such that the entire edge has the bevel.
  • bevel defines an angle compared to the longitudinal direction, specifically deviating from 90°, as is the case for the straight edge running in the transverse direction in the prior art.
  • the edge can have precisely one bevel running at the angle in question to the longitudinal direction. In this case, the edge and the bevel coincide, as it were.
  • the edge is equipped with two or more bevels.
  • the two slopes can be mirror-symmetrical to the longitudinal direction of the carrier.
  • the design is regularly made such that exactly one bevel is equipped with at least one edge-side tip. If two bevels are used, the two bevels taken together define a central peak or two peripheral peaks.
  • the shape of the tip ensures that an assembly worker grasps it visually and/or haptically much more easily than the transversely running edge in the prior art, and consequently the winding end can be easily detached from the winding. This applies both to the case that the textile backing is equipped with a full-surface and uninterrupted adhesive coating and when working with a punctiform or strip-shaped adhesive coating.
  • the angle of the slope is more than 0° and less than 90°.
  • the angle of the slope can be more than 10°, preferably more than 20° and particularly preferably more than 30°.
  • the upper limit of the angle of inclination preferably less than 80° and more preferably less than 70° is observed.
  • the invention is based on the knowledge that the plastic fibers usually used to produce the textile carrier, which are made of polyester, polypropylene, polyamide, etc., for example, melt briefly and then immediately solidify again.
  • the edge and of course also the bevel realized there are laid out free of lint and threads.
  • a comparable sealed edge and/or bevel can also be realized and implemented by defining the edge, including the bevel, with the aid of one or more rotating and, for example, heated knives. This describes, among other things, the utility model DE 202011 110445 U1 mentioned in the introduction.
  • the sealed edge or bevel has a two-fold effect in that any fluff or threads adhering to the roll are avoided on the one hand and on the other hand the edge experiences a haptic marking as it were.
  • the edge and/or the bevel can also be equipped with a haptic and/or visual marking.
  • a haptic marking can be implemented, for example, by a paint applied in this area.
  • an optical marking is achieved at the same time.
  • a variant is particularly preferred in which the carrier is provided with the adhesive coating on its carrier top and has a marking on its carrier underside at least in the region of the winding end. Since the underside of the carrier defines the roll during production of the roll and consequently also the area of the end of the winding, it is sufficient in this connection to equip the underside of the carrier in question with the mentioned marking, at least in the area of the end of the winding.
  • the marking can be haptic and/or optical.
  • a visual marking it is conceivable that the underside of the carrier in question is equipped with a colored stripe in the region of the winding end, for example.
  • This color stripe can be applied, for example, as a transverse stripe to a web of fabric or fleece on the underside of the carrier at the same time for all the rolls produced from it.
  • the colored transverse stripes in question can also be taken into account from the outset during the production of the woven web or fleece web.
  • the different color design in the area of the end of the winding ensures that the end of the winding and consequently the edge on the end of the winding that is equipped with the at least one bevel stand out particularly visually and contrast with the different color design. This makes it easier to find and to detach the edge equipped with the bevel from the roll with a simple feel.
  • a haptic marking can also be used at this point. This is the case, for example, when a paint strip, a plastic strip, etc. is applied as an alternative or in addition to the transverse strip mentioned above.
  • the additional attachment of an adhesive strip in the transverse direction to the carrier web is also conceivable, as long as the underside of the carrier is equipped with a haptic and/or optical marking implemented in this way, at least in the region of the end of the winding and consequently of the winding produced. In both cases, this makes it easier for the assembly worker to find the at least one point mentioned above and consequently the processing of the adhesive tape wound on the roll and in particular the winding tape is significantly simplified compared to the prior art.
  • the textile backing can be a fleece, a woven fabric, a velor, a knitted fabric, a scrim, etc. Combinations are also conceivable. Accordingly, a corresponding textile backing web is typically used, which, after being coated with the adhesive coating on the top side of the backing, is cut lengthwise into the individual strips to produce the adhesive tape wound up on the roll.
  • the textile backing can be single-layer or multi-layer. In the latter In this case, for example, a combination of a fleece and a woven fabric is conceivable.
  • Such an embodiment is characterized by a particularly abrasion-resistant and noise-dampening effect.
  • the procedure here is usually such that the layer of fleece is equipped with the adhesive coating and consequently defines the top side of the carrier.
  • the layer of fabric is found on the underside of the support and consequently faces outwards in the roll being produced.
  • the textile backing generally has a basis weight of 50 g/m 2 to 500 g/m 2 .
  • All replaceable adhesive coatings in this area can be used as the adhesive coating, for example those based on a dispersion adhesive.
  • an acrylate-based hotmelt adhesive is used, which is typically applied to the top side of the carrier over the entire surface or in the form of strips with the aid of one or more nozzles.
  • basis weights in the range from 50 g/m 2 to 250 g/m 2 are generally observed for the adhesive coating.
  • an adhesive tape wound up on a roll is made available, which is particularly and advantageously a winding tape for sheathing cables in automobiles.
  • Such wrapping tapes are regularly designed to be torn by hand and have medium to high abrasion resistance.
  • an adhesive coating designed as a pressure-sensitive adhesive is usually implemented. So that the winding tape wound up on the roll can be processed particularly easily and quickly and thus inexpensively, the winding end of the adhesive tape or winding tape glued to the roll is provided with an edge equipped with at least one bevel for haptically easy detachment from the roll.
  • the at least one bevel ensures that at least one point is defined on the edge in question at the end of the winding, be it at the edge of the end of the winding or also centrally.
  • This at least one tip can be felt particularly easily by touch and thus facilitates the detachment of the adhesive tape from the roll.
  • the edge in question and equipped with the bevel can be felt particularly easily or stands out visually, which simplifies processing even more. This is where the main advantages can be seen.
  • FIG 3 shows a view from above of the winding end with the edge in question and the winding arranged underneath.
  • the adhesive tape is a wrapping tape 1, shown in particular in FIGS. 2A to 2C and 3, for sheathing cables in automobiles.
  • the adhesive tape or wrapping tape 1 has a textile backing 2 and an adhesive coating 3 on at least one side of the backing 2.
  • the enlarged view in FIG is arranged pointing to the outside and the adhesive coating 3 is on the inside.
  • This means that the adhesive coating 3 is applied to the top side of the carrier, whereas the underside of the carrier 2 is generally provided without an adhesive coating 3 .
  • a lacquer or film coating or also a color coating can also be applied at least in regions to the underside of the carrier, as will be explained in more detail below.
  • the procedure is typically such that a textile backing made of, for example, a woven fabric or fleece is provided with the adhesive coating 3 and then cut in the longitudinal direction.
  • the individual strips produced in this way from the winding tape 1 are then wound up to form the roll shown in FIG.
  • the respective winding end 4 shown must be defined.
  • At least one cutting device is provided for this purpose, which cuts the individual strips of adhesive tape or wrapping tape 1 to length, as described and illustrated in the drawing in PCT application WO 2017/009049 A1, which was referred to at the outset and goes back to the applicant is.
  • the winding end 4 is now defined in such a way that the winding end 4 glued to a winding 5 has an edge equipped with at least one bevel 6 for easy detachment from the winding 5 in terms of feel. This is shown in particular in FIGS. 2A to 2C, where under different embodiments of the edge with the bevel 6 provided at this point are shown in the drawing.
  • FIG. 2A shows the variant in which the edge in question at the winding end 4 has exactly one bevel 6 running at an angle a to the longitudinal direction L of the carrier 2 . That is, in this case the edge and the bevel 6 coincide. As a result of this, a tip 7 is formed at least on a longitudinal edge of the carrier 2 .
  • the angle a of the bevel 6 and thus of the edge at the winding end 4 with respect to the longitudinal direction L assumes values of approximately 40° to 60° or 70° in the example and can of course be varied. This is ensured by a corresponding cutting device, which defines the bevels 6 in question and the angle a as well as the edge and thus the winding end 4 .
  • the cutting device can be an ultrasonic cutting device, a laser cutting device, a cutting device with a knife beam or also one with rotating knives. Of course, combinations are also conceivable.
  • the cutting device can in principle operate in such a way that it ensures that the edge or bevel 6 in question is sealed. This is the case when the textile backing 2 is made of plastic fibers and the melting temperature of these plastic fibers is briefly exceeded at least in the area of the edge or bevel 6 with the aid of the cutting device. - The previously mentioned angle a of the slope 6 compared to the longitudinal direction L is also observed with the same size in part between the longitudinal edge of the carrier 2 and the bevel 6 in question.
  • Figs. 2B and 2C a variant is shown in the form of a drawing in which the edge is equipped with two or more bevels 6. In fact, two bevels 6 are realized at this point, which together form the edge.
  • serrated incisions can basically also be used in the area of the edge and consequently in the area of the winding end 4, as are described in detail in DE 102012202635 A1.
  • the design is such that the respective jagged incision ends in the tip 7 .
  • the individual incisions may form a closed zigzag line.
  • a punch may be used as the cutting device. In any case, it is clear that in principle a large number of tips 7 can be realized at the end of the winding 4, which is not shown in detail, however.
  • the two bevels 6 in the exemplary embodiment shown are designed to run mirror-symmetrically to the longitudinal direction L of the carrier 2 according to the exemplary embodiment.
