Definitions

  • the present invention relates to an adhesive closure part for producing an adhesive closure according to the preamble of claim 1 and to a method for producing an adhesive closure part according to the preamble of claim 14.
  • the adhesive closure part is the one part of an adhesive closure device.
  • the adhesive closure device is completed by a further adhesive closure part which has a multiplicity of fibers in a non-oriented arrangement, which engage the hooking means of the first adhesive closure part and ensure a connection of the adhesive closure device.
  • cost-effective fastener parts are used with less fiber content. This results in the need to make the complementary adhesive closure parts more effective.
  • One way to increase the efficiency is to reduce the size of the entangling means so as to allow a larger number of entangling means per square centimeter. However, this makes it difficult to form the interlocking means, especially in more complicated shapes thereof.
  • too high a number of entangling means per unit area is disadvantageous, since it leads to a repellent effect for the counter-adhesive closure part.
  • a generic adhesive closure part is already known from EP 1 309 257 B1.
  • the adhesive closure part comprises a stalk and a head part with STIPPL Patent Attorneys
  • each rotationally symmetrical shape in the form of a hyperboloid After removal of the adhesive closure part, the head region can be reshaped in a downstream calendering process.
  • the holding action of the hooking means is the same along the entire circumference of the head part in the generic adhesive closure part.
  • interlocking means are also formed, for example, with a cross-shaped stalk on a carrier and the head area of each interlocking means in a downstream calendering process by means of a counter-mold associated with each interlocking means in the area the calendering roller is provided with a roof-shaped form.
  • the particular hooking of Verhakungsmittels is achieved in that a special contouring of the outer circumferential edge is achieved by the counter-mold.
  • this method is structurally very complicated.
  • DE 1 610 318 discloses a separable closure whose elements consist of a plurality of headed pins in a flexible base plate for use on garments and the like.
  • a plurality of pins are disposed on a surface of a plate.
  • Each pin has the shape of a body of revolution and consists of a rod which is surmounted by an enlarged head.
  • the pins are arranged in staggered rows.
  • the object of the present invention is to provide a novel adhesive closure part of the generic type, which on the one hand ensures an increase in the Verhakungs binelles and on the other hand can be produced by means of a relatively simple procedural device.
  • the head part Due to the fact that the head part is substantially flattened in the region of its end face, it is not necessary to provide a counterform in the area of the reworking roll which is individually assigned to the respective head part for the formation of the head part. Rather, the adhesive closure part can be aftertreated with a common roller, for example calendering roller or the like. Due to the non-rotationally symmetrical shape of at least the head part, preferably the head part and the stem, results in the post-treatment by means of heat not uniformly distributed along the circumference flow behavior, resulting in the irregular extension of the edge projection to the wearer and an increased hook effect in a particular direction established.
  • the regions of the edge projection which extend more towards the carrier, can be arranged in the shape of a cross in the region of the head part.
  • the aforementioned embodiment ensures a high mechanical strength of the foot region of the stem.
  • the head part may have four outwardly facing areas, of which at least one area in plan view has a different length than the other areas, so that adjusts a non-rotationally symmetrical shape.
  • the four regions can be arranged substantially cross-shaped in plan view to each other. Due to the different length of at least one area in at least one direction results in a correspondingly directed holding force. This allows a corresponding adaptation to the opposite adhesive closure part (e.g., suede).
  • the adhesive closure part with such hooking means thus also allows adaptation to the requirements of the respective adhesive closure device.
  • the special orientation of the interlocking means ensures easier penetration into the fibers of the opposite adhesive fastener in a particular preferred direction.
  • a directed holding force of the entire adhesive closure device e.g. in the arrangement on a baby diaper can be of particular advantage by higher deduction values are achieved in a certain deduction direction than in another direction.
  • exactly one area in plan view may be longer than the other areas, whereby a directional holding force is established on a carrier with a corresponding arrangement of a plurality of hooking means.
  • the at least one region which is longer than the other regions, can have an edge projection which extends more towards the carrier than the other regions.
  • the edge projection which extends more towards the support leads to increased entanglement with the oppositely engaging adhesive closure part, which in turn results in a directed holding force in a specific preferred direction.
  • z. B. the entire adhesive closure part be completely asymmetrical at least in plan view.
  • the pull-off force in a certain direction can thus be set individually.
  • the interlocking means can, viewed in cross-section, essentially have the shape of an unequal triangle. This shape is not rotationally symmetrical and thus ensures different trigger values in different take-off directions.
  • each seen in cross section the stem and / or the head part have substantially the shape of an unequal triangle.
  • the cross-sectional shape does not exactly correspond to that of a non-isosceles triangle, since especially the corner areas are rounded and blended into the side areas.
  • the shape of an unequal triangle can also be reproduced essentially only in rough form.
  • the areas of the edge projection, which extend more towards the carrier, are in particular at the corner regions of the head part, which essentially is the STIPPL Patent Attorneys
  • the transitions between the regions in which the edge projection extends more towards the carrier and the regions in which the edge projection extends less towards the carrier flow into one another.

  • the stem may be formed in the intersection region of the four regions of the head part or in the center of gravity of the non-isosceles triangle, resulting in a particularly stable connection.
  • the at least one region that is longer than the other regions may protrude more towards the stem than the other regions. The hook effect of the longer range can thus be fully utilized.
