Definitions

  • the present invention relates to the field of fastening or closing profiles.
  • Such fastening or closing profiles are used in various fields and in particular in the field of the display or manufacture of covers for the protection of objects, or more generally in the field of manufacturing. packing bags.
  • advertising support films folded on themselves in a closed loop are frequently used and thus connected, at their ends made adjacent, by the aforementioned elements or fastening profiles. These films are generally driven to move next to a window to change the range of information thus made visible.
  • attachment or closure can be subject to many embodiments. It may be complementary hooks, complementary male / female structures or velvet type systems or loops / hooks, or any equivalent system.
  • Such fastening or closing profiles are generally packaged in the form of a strip wound on a support mandrel.
  • One of the problems in industrial use is the connection between the end of such a supply and the beginning of a subsequent supply to supply a production machine.
  • the document FR-A-2036112 discloses a method for producing slide fasteners in the form of lengths of a continuous spiral-type slider closure chain.
  • the method described consists in detaching a succession of zipper lengths from the continuous chain by transverse cutting lines passing through the ribbons and spirals.
  • the method comprises a step of heating the plastic spirals in order to preserve the convolutions and to prevent the plastic spirals from loosening or detaching.
  • the zippers obtained by this method are provided with usual extensions at their longitudinal ends.
  • the present invention also relates to a guide for implementing the above method, comprising respective alignment means of the two sets while leaving access to at least a portion of the superimposed areas of the two sets.
  • the aforementioned guide comprises on the one hand, a longitudinal groove adapted to receive in mutual alignment position the attachment means or closure of said profiles and on the other hand, blades flanking the groove and adapted to take a position between support sails of said sets.
  • the plate has a length of the order of 10 to 15 cm and a width of the order of 1 to 2 cm.
  • the plate 10 is provided, in the vicinity of one of these ends of a hole or eyelet 12 through to facilitate its handling and / or storage by hanging on a support.
  • a hole or eyelet 12 does not intervene directly in the connection process according to the present invention.
  • the plate 10 defines on the one hand, a longitudinal groove 20 adapted to receive in the mutual alignment position the fastening or closing means 112, 122 of the profiles 110, 120 to be connected and on the other hand, blades 30, 32 flanking this groove 20 and adapted to take position between support webs 114, 124 of said sets.
  • Such a groove 20 and such blades 30, 32 may be subject to many embodiments.
  • these means are made by means of a longitudinal cut, the plate 10 opening on the longitudinal end thereof opposite to the eyelet 12.
  • the groove 20 is formed by a longitudinal rectilinear slot formed halfway in the plate 10.
  • the width of this slot forming the groove 20 is complementary to the width of the closure means 112, 122. It is typically of the order of a few mm.
  • the two blades 30, 32 are formed on either side of the groove 20.
  • the slot forming the groove 20 opens on the longitudinal end of the plate 10 opposite the eyelet 12 in the form of a flared cutout dihedron concave delimited by two straight edges in V 31, 33 forming bevels at the end of the blades 30, 32.
  • this flared cutout is intended to facilitate the engagement of closure profiles.
  • the slot forming the groove 20 opens into an oblong slot 40 whose largest extension extends transversely with respect to the longitudinal axis of the plate 10.
  • This oblong slot 40 is intended to receive one of the sets.
  • the length of the light 40 oriented transversely to the longitudinal axis of the plate 10 is preferably at least equal to the width of the webs 114, 124 of the closure assemblies.
  • the oblong slot 40 has a length (transverse to the longitudinal axis of the plate 10) of the order of 10 to 15 mm, while the width (parallel to the longitudinal axis of the plate 10) is from order of 5mm.
  • the groove 20 typically extends over half the length of the plate 10.
  • the plate 10 can be made of any suitable material, for example metal or thermoplastic materials.
  • connection method according to the present invention will now be described.
  • the first step is to cut the ends of the two sets to be connected so that each of them has two elements whose respective ends are offset relatively in the longitudinal direction.
  • the longitudinal gap between the ends of these two elements is typically of the order of 1 to 5 cm.
  • the longer element is a female element, while for the second set, the element of greater length is of complementary male type.
  • the element whose web is referenced 114 has a length greater than the element whose web is referenced 124.
  • the subsequent steps are to engage the two sets on the guide 10.
  • one of the assemblies is engaged by the end of the groove 20 adjacent to the light 40.
  • the veil 114a of great length is engaged in the lumen 40 and then slid into the position underlying the blades 30 32 while the web 124a of shorter length is positioned above them.
  • closure means 112a, 122a of these elements are placed in the groove 20.
  • the second set is engaged on the guide 10 by the longitudinal end thereof.
  • the second set is inverted with respect to the first. That is to say, if for the first assembly the veil 114a of great length is slid in the position underlying the blades 30, 32, conversely for the second set the veil 114b of great length is placed above those ci, while the veil 124b of shorter length is placed in position underlying the blades 30, 32.
  • the groove 20 prevents overflow of the weld.
  • the weld can be automated with a bar and spikes.
  • the sets can be fixed by ultrasonic welding at the groove 20.
  • the welding zone preferably relates to the superposed parts of the two sets. It may, however, also extend in part on each of these two sets beyond the aforementioned superimposed zones.
  • the method according to the present invention provides an assembly having a tensile strength superior to the state of the art.
  • the fastening or closing profiles which may be used in the context of the present invention, may be the subject of any appropriate variant. It is advantageously of profiles in thermoplastic materials, for example polypropylene.
  • sets 100 comprising two elements 110, 120 respectively comprising closure means or attachment 112, 122 carried by webs 114, 124.
  • FIG 8 a first embodiment according to which the hooking or closing means are formed of hook structures 112, 122.
