Definitions

  • ABSTRACT A method for applying small prefabricated stop members and drawing sliding clasps onto sliding-clasp fastener tapes comprising attaching two upper stop members and one lower stop member at top and bottom ends of an engaged fastener tape, the lower member fitting over the engaged teeth of the top and providing a lower stop for the travel of the clasp, while the upper stop members are fitted in outwardly splayed fashion with the divergent ends in the direction of the tape advance so that the moving clasp can back over these members in traveling toward the lower stop member.
  • FIGA INVENTOR METHOD FOR DRAWING SLIDING CLASPS AND FIXING STOP MEMBERS ONTO ENGAGED SLIDING-CLASP FASTENER TAPES wherein members for limiting the clasp movement are attached to the tape before the clasp is inserted.
  • the stop means for limiting the travel of the clasp are attached to the fastener tape before forming the gaps and before inserting the clasp, and to this end, a thermoplastic material, for example a synthetic plastic film, is melted onto the tapes at the site of the gap in the teeth, and the plastic material is then molded to shape the stop members for limiting the travel of the clasp.
  • a thermoplastic material for example a synthetic plastic film
  • An object of the invention is to provide economical and efficientfitting of clasps to continuous, engaged, sliding-clasp fastener tapes, whereby stop or limiting members are attached to limit the movement of the clasp travel members by method steps which are carried out at high operating speeds and which do not make the fastener ends stiff or hard to manipulate for later fastener attachment.
  • this object is achieved by a method wherein prefabricated, elongated and relatively small stop members serve as limiting members and wherein these stop members are directly secured to the supporting ribbons of the fastener tapes.
  • two upper stop members and one lower stop member are used, the two upper limiting members being disposed away from the center in outwardly splayed fashion in the direction of tape advance, so that the clasp which is to be fitted can run back over these two upper members.
  • the lower limiting member is fitted over the engaged rows of teeth atright angles and engages these teeth to provide a sharply defined lower stop for the travel or movement of the clasp.
  • U- shaped metal staples are used as the limiting members
  • These metal staples may be the commercially available, common metal staples which are used for fastening paperor cardboard, and, because of their low cost, do not appreciably affect the total cost of the fastener.
  • the staples can be attached to the ribbons with the very simple, portablecommercial stapling machines and at practically any speed desired, so that the maximum operating speed obtainable for the clasping fitting process as a whole is no longer determined by the application of the limiting members, as it is in the prior art method for molding these stop members from synthetic plastic material.
  • U-shaped syntheticplastic staples orsynthetic plasticbars with push-through projections are used as the limiting members and the staple portions or projections are pushed through the supporting ribbons and are deformed under the application of heat and res sure to form anchoring elements on the reverse or under side of the supporting ribbon.
  • the use of prefabricated synthetic plastic limiting members of this kind prevents wastage of material and reduces the deformation of the tape to a minimum, while the anchoring members can be applied with very simple, portable devices, necessitating cooling times and cooling lines which are short and permitting a high production rate.
  • prefabricated synthetic plastic bars with flat undersides are welded to the fabric of the supporting ribbons and are used asthe limiting members.
  • the novel method is particularly suitable for woven sliding-clasp fasteners in which the teeth are formed from woven-in synthetic extruded plastic sections.
  • FIG. 1 is a plan view of two, engaging sliding-clasp fastener tapes
  • FIG. 2 is a side elevation of the tapes shown in FIG. 1, with a device for inserting the sliding clasp;
  • F IG. 3 shows a section through a clasp travel limiting member, on a line III- III in FIG. 1;
  • FIG. 4 represents a section along a line lV-IV in FIG. 3;
  • FIGS. 5 and 7 show two alternative forms of clasp travel limiting members
  • FIG. 6 represents a section along a line Vl-Vl in FIG. 5.
  • FIG. 1 shows two engaged sliding-clasp fastener tapes 1, each consisting of a supporting tape 2 and a row 3 of teeth.
  • the engaged tapes I are moving in the direction indicated by an arrow 4.
  • three limiting members are attached to the engaged tapes 1 for every individual fastener length.
  • One of these limiting members constitutes the lower limiting member 5, which is disposed over the two engaged rows 3 of teeth at right angles to these rows, engages these rows, andis fixed to the two supporting tapes 2 by its ends.
  • the two upper limiting members 6 are disposed away from the center of the tape and are splayed upwardly, that is, in the direction of travel or advance4 of the clasp. Between the lower limiting member 5 and the upper members 6, enough space is left for a gap or a punched-out hole 7 in the teeth which is of the same size as the sliding clasp.
  • FIG. 2 there is shown a sliding clasp 9 which is inserted into the hole or gap 7 by means of a feeding device 8, so that the clasp 9 lies in the same plane as the tapes 1 and its open end faces the upper limiting members 6.
  • a feeding device 8 As the fastener tapes 1 continue to advance, their rows 3 of teeth enter the lateral channels provided for them in the clasp 9, and the front ends of the tapes 1 disengage and splay apart so that the clasp 9 runs over the limiting members 6.
  • the feed device 8 then releases the clasp 9, which has now been fitted to the fastener tapes and is entrained by these tapes.
  • each fastener length in the endless fastener tapes receives its clasp.
  • the tapes are then simply cut at the gaps or holes 7 to make the individual fasteners.
  • the stop members 5, 6 are in the form of staples made of metal wire and bent to form a U.
  • the ends 10 of the staples are pushed through the supporting tape 2 and bent back towards one another.
  • FIGS. 5 and 6 illustrate a modified embodiment of the limiting members which consist of an elongated strip 11 of synthetic plastic with two integral, originally pointed push-through projections 12 on its underside.
  • the ends of the projections 12 When the ends of the projections 12 have been pushed through, they are heated and flattened in the same manner as rivet heads are pressed, so that the strip 11 is joined firmly to the tape.
  • the limiting members may be prefabricated, elongated synthetic plastic bars with flat undersides which are placed on the supporting ribbon. Heat and pressure are applied, and the bars are welded and cemented onto the fabric of the supporting tape.
  • said lower and upper stop members are each a U-shaped metal staple having protruding ends which push through the tape parts and are reversedly bent on the underside of said tape parts.
  • lower and upper stop members are each a U-shaped thermoplastic staple having projecting portions which are pushed through the tape parts and are deformed under the application of heat and pressure to form anchoring elements on the underside of said tape parts.
  • lower and upper stop members are each a synthetic plastic bar having a flat underside which is welded under heat and pressure to the fabric of the supporting tape parts.
