Definitions

  • the invention relates to a method for producing an adhesive closure part, comprising at least one plastic material, in which a support member having a plurality of projecting handle parts with individual head parts is connected such that at least a part of said handle parts whose free ends in touching or immersing plant with an investment side of each assignable headboard come, which are still present at least in the partially liquid or partially plasticized state during the connection process of handle parts and assignable headboards and the headboards are fully cured after the connection.
  • the invention further relates to a device for producing an adhesive closure part with the method.
  • Adjacent adhesive closure parts which are also attributed to the mechanical fastening elements, form a closure which can be repeatedly opened and closed with complementary closure parts, wherein hooks or mushroom-like closure parts interact with loop-like closure elements of another adhesive closure part to form the adhesive closure. Solutions are also known in which the same adhesive closure elements of two different adhesive closure parts interact with one another (hermaphroditic closure).
  • the US 2003/0126724 A1 discloses a fastener closure member having a sheet-like support member and a plurality of handle parts, which are arranged as projections on the support member and each composed of a soft, elastic-flexible resin material and a hard, solid resin material.
  • each of the shaft of the stem part of the hard resin or plastic material and its upper part may be formed from the soft resin or plastic material.
  • the US Pat. No. 6,180,205 B1 a manufacturing method using a forming roller, in which a band-like support member is connectable to a plurality of relatively large dimensionable hook closure elements.
  • the shaping roller has hook-shaped form recesses on its outer circumference, in which plastic material is pressed in through a first extruder device in order to fill the mold. Excess plastic material on the outer peripheral side of the forming roll is removed by means of a Schneidabtrag Rhein, which is referred to in technical language as a doctor blade.
  • the carrier part material is then applied by means of a second extruder device arranged downstream in the direction of manufacture, and with the hook-shaped closure parts during the Cooling process of the roller firmly connected.
  • a peel roller then removes the finished closure from the former. Due to the hook geometry, this can lead to difficulties during the demolding process and, furthermore, during the production process, a relatively high proportion of plastic waste arises due to the use of said doctor blade.
  • the adhesive closure part produced in this way which is intended in particular to serve as a closure for baby and incontinence diapers, is relatively stiff and, to that extent, still leaves desires open with regard to the closure characteristic.
  • the hooking means produced in a conventional manner consist of individual handle parts, at whose free ends plate-like interlocking heads are present.
  • the materials forming the additional headers are applied to the hooking heads via an applicator roll.
  • the typically used acrylate material has a similar consistency and viscosity as honey and forms a kind of application bath between the applicator roll and a counter-roller and can be passed from there successively from the applicator roll to the adhesive closure part.
  • the surface tension of the acrylate material is selected to provide some form of drop formation with the result that the headers form hemispherical caps on the hooking heads.
  • Energy is supplied to the hooking heads, for example in the form of UV radiation and / or in the form of heat.
  • the invention has the object to further improve the known solutions while maintaining their advantages, especially at low production costs to provide a functionally reliable adhesive closure, which is adjustable in its wide behavior of its behavior.
  • This object is achieved by a method having the features of patent claim 1 and a device having the features of claim 4.
  • the method according to the invention serves to produce an adhesive closure part, preferably consisting of at least one plastic material, characterized in that head part material is provided in a molding tool having a multiplicity of individual mold recesses configured in accordance with the respective head geometry, and in that the free ends of the stem parts when approached on or at the time of introduction into the mold recesses touch the at least partially liquid or partially plasticized plant sides of the head parts and / or immerse in the head part material.
  • a device has been found in which for the individual head parts a mold is present with a variety of mold cavities corresponding to the respective head geometry and with a feeder for the already finished support member with the handle parts whose free Ends are inserted by means of the feed device in the mold recesses.
  • stem and head parts consist of different plastic materials, in particular the stem parts are formed from a thermoplastic material and the head parts made of acrylate.
  • the relatively hard acrylate material for the respective head part allows a robust Unterhakungsdorfkeit for the loops of a corresponding adhesive closure part, so that an adhesive closure constructed in this way allows very high adhesion and peel strength values.
  • the inventive method is based on the manufacturing device according to the Fig. 1 explained in more detail.
  • the inventive method is used to produce a designated as a whole with 10 adhesive closure part, in which a band-shaped support member 12 is connected to a plurality of projecting stem parts 14 with individual head parts 16 such that at least a portion of said stem parts 14 whose free ends 18 in touching or immersion plant come with a plant side 20 of each assignable head part 16.
  • a band-shaped support member 12 is connected to a plurality of projecting stem parts 14 with individual head parts 16 such that at least a portion of said stem parts 14 whose free ends 18 in touching or immersion plant come with a plant side 20 of each assignable head part 16.
  • a mold designated as a whole with 22 is provided with a plurality of individual mold recesses 24, which correspond in terms of their design to the respective head geometry.
  • the mold recesses 24 are part of a circulating in the manner of a conveyor belt forming belt 26, wherein the mold recesses 24 of the upper run are filled with plastic material and the lower run substantially the empty mold recesses 24 leads.
  • the mold recesses 24 are in turn in the transverse and longitudinal direction of the forming belt 24 - in regular or irregular distribution - multiple available.
  • a feed device designated as a whole by 28 is provided for the already finished carrier part 12 with the handle parts 14, the free ends 18 of which can be introduced into the mold recesses 24 by means of the feed device 28.
  • the feed device 28 has a kind of supply roll 30, from which the stem part closure material can be unwound.
  • the strip material can perform the mold 22 and the complete adhesive product is at the end on a designated 34 transport roller for further transport wound.
  • the individual transport and management facilities were omitted; likewise, the heating and cooling devices for the manufacturing device are not shown.
  • the transport direction of the mold 22 and feed device 28 is represented by the arrow 36.
  • the mold recesses 24 are open to the outside, so freely accessible from there, wherein for filling the mold recesses 24 of the mold 22, a filling device 38 is used, which, without being specified, may be a conventional extruder application device; however, preferably represents a droplet applicator that does not completely fill the mold recesses 24 to the free edge with plastic material without the mold recesses 24 overflowing.
  • the filling device 38 may also be designed in the manner of a doctoring device for the plastic material, with excess plastic material being removable from the upper side of the strip by means of the so-called doctor blade device (not shown).
  • the curing device 40 may be a common heat source, but also a UV emitter and the like. If an acrylate material is used for the head parts 16, the curing device 40 is preferably a UV radiation source.
  • Adhesive closure parts produced by the method shown using the device described, are enlarged in the FIGS. 2 and 3 reproduced, wherein the head parts 16 as shown in the Fig. 2 are designed to be substantially flat towards their free end side, which allows them to form very narrow or thin-lipped with respect to their environmental edge; unlike the closure solution after the Fig. 3 in which the top side of the head part 16 shown is curved in a convex manner, so that this head part 16 ends towards the surrounding edge 42 with a thicker wall than the solution according to FIG Fig. 2 , Both solutions have in common that the head part 16 consists of an acrylate material, whereas the stem part preferably consists of a thermoplastic material, in particular of polyamide, polypropylene or polyethylene. Other material combinations are possible here.
  • the carrier part 12 itself can also consist of a multi-extrusion layer arrangement or have a film-like, elastically extensible character.
  • the said head parts 16 can form spherically shaped, outwardly smooth shell bodies seen from above; but here are also realizations in polygonal shape, especially in hexagonal shape possible. By using acrylate material for the head parts 16, these also form a kind of edge protection towards their environmental edge 42, which in turn benefits the longevity of the overall closure.
