Definitions

  • the invention relates to a method for producing an adhesive closure part, preferably consisting of at least one plastic material.
  • the invention further relates to a device for carrying out the method and an adhesive closure part produced by the method and using the device according to the invention.
  • Adjacent adhesive closure parts which are also attributed to the mechanical fastening elements, form a closure which can be opened and closed again and again 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).
  • US Pat. No. 6,180,205 B1 proposes a production method using a forming roller in which a band-like carrier part can be connected to a multiplicity of hook closure elements that can be dimensioned relatively large.
  • 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 I referred to professional language as a doctor blade.
  • the carrier part material is then applied and fixedly connected to the hook-shaped closure parts during the cooling process of the roller.
  • a peel roller then removes the finished closure member from the former. Due to the hook geometry, this can lead to difficulties during the demolding ungsvorganges and further arises in the manufacturing process, a relatively high proportion of waste plastic due to the use of said doctor blade.
  • a band-like carrier part which already carries on its upper side granular agglomerates as stem parts, on which then the half-shell-shaped head parts can be placed.
  • the adhesive fastener part thus prepared which is intended to serve as a closure for baby and incontinence diapers, in particular, is relatively stiff and so far leaves nothing to be desired with regard to the closure characteristic.
  • the invention provides the task of the known solutions while maintaining their advantages further improve, especially at low production costs to provide a functionally reliable adhesive closure, which is adjustable in many areas of its closure behavior ago.
  • This object is achieved by a method having the features of claim 1; a device with the features of claim 3 and a fastener closure part with the features of claim 6.
  • the inventive method is used to produce a fastener part, preferably consisting of at least one plastic material which is characterized in that a support member is connected to a plurality of projecting handle parts with individual head parts such that at least a portion of said handle parts whose free ends in touching or submerged installation with an installation side of the respectively attributable head part.
  • a device has been found to be particularly economical for carrying out the method, in which a molding tool is present for the individual head parts with a plurality of mold recesses which correspond to the respective head geometry and with a feed device for the already finished carrier part with the handle parts, the free ends of which can be introduced by means of the feed device into the mold recesses.
  • a particularly functional and mechanically robust adhesive closure part is then provided that stem and head parts consist of mutually different plastic materials, in particular the stem parts are formed from a thermoplastic material and the head parts made of acrylate material.
  • 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 a so constructed adhesive closure allows very high adhesion and peel strength values.
  • Figures 2 and 3 in side view different embodiments of the producible adhesive closure part.
  • the inventive method is used to produce a designated as a whole with 10 adhesive closure member 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 immersing plant with an investment side 20 of each assignable head part 16 come.
  • the method according to the invention provides that in the actual connection process of handle parts 14 with the assignable head parts 16, these are still present at least in partially liquid or partially plasticized state and the head parts 16 are completely cured only after the connection.
  • the free ends 18 of the handle parts 14 thus touch the still at least partially liquid ubenit 20 of the head parts 16 or even dive preferably in the headboard material in order to ensure the compound in the later cured state of the head parts 16 can.
  • 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 feeder 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 molding tool 22 and feeding device 28, however, is represented by the arrow 36.
  • the Formausnaturalun- gene 24 are open to the outside, so freely accessible from there, wherein for filling the mold recesses 24 of the molding tool 22 is a filling device 38 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 formed in the manner of a Aufrakelvorraum for the plastic material, wherein excess plastic material from the top of the tape by means of the so-called. Doctor-loading device (not shown) is removable.
  • the curing device 40 may be a common heat source, but also a UV emitter and the like. If an acrylic 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 shown enlarged in Figs. 2 and 3, wherein the head portions 16 are formed according to the illustration of Figure 2 to its free end side substantially flat, which allows Narrow or narrow these down according to their environment border form thin-lipped; in contrast to the closure solution according to Figure 3, in which the top of the head portion 16 shown is convexly curved, so that this head portion 16 to the perimeter edge 42 towards thicker expires than the solution described above according to the Fig.2.
  • Both solutions have in common that the head part 16 consists of an acrylic 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 a foil-like, elastically extensible character to have.
  • 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.
