Definitions

  • This invention relates to slide fasteners, and more particularly to an improved separating end connection therefor and method of making the same.
  • Slide fasteners manufactued in the conventional mannerner comprise a pair of continuous stringer tapes having a series of spaced apart interlocking fastener elements attached to their opposed beaded edges with the opposed elements of the respective fastener elements interengaged.
  • the fastener elements are arranged in groups along the stringer tapes so as to provide a gap between each group such that slide fastener chain manufactured in this manner is called gap chain.
  • Each group of fastener elements designates the length of fastener desired.
  • the tape ends of the individual fastener are then stitched along their severed edge to prevent the threads from unraveling; and, if a reenforced tape end is desired, the tape areas adjacent these edges can be suitably cross stitched to provide a reenforced tape end.
  • the length of slide fastener is then separated and a separating end connection is then secured to one end of the fastener with the retainer on that tape of the fastener upon which the slider is mounted. Suitable end stops are secured to the opposite end of the fastener.
  • a fastener manufactured in this fashion is used in jackets and the like wherein the fastener is opened and the two stringers are completely separated from each other to ease the removal of the garment. It is to an improved separating end connection and reenforced tape end and to a method of manufacturing the same from gap chain that the present invention is directed.
  • Another object of this invention is to provide end connections for a separating type slide fastener having reenforced tape ends formed integrally therewith.
  • Still another object of this invention is to provide an improved method of making combined reenforced tape ends and their respective elements for a separating end connection, which elements can be applied to both stringer tapes simultaneously and positioned accurately along the respective beaded edges of the stringer tapes.
  • a further object of this invention is to provide a separating end connection for a slide fastener in which the pin and retainer members on their respective stringer tapes will be positively locked during the normal operation of the slider.
  • Still another object of this invention is to provide improved reenforcing tape ends and separating end connection made of thermoplastic which can be conveniently and inexpensively fabricated and applied to the stringer tapes while in chain form and before they are cut apart from one another.
  • Another object of this invention is to provide apparatus for the manufacture of the separating end connection for a slide fastener in which a separable mold is capable of molding the pin member and the retainer member directly on the opposed edges of a pair of stringer tapes in a single operation.
  • FIG. 1 is a plan view of a finished slide fastener showing the completed separating end connection assembled thereon;
  • FIG. 2 is a bottom end view of the separating end connection shown in FIG. 1;
  • FIG. 3 is an enlarged plan view of the separating end connection shown in FIG. 1 with the connection in the separated condition;

  • FIG. 14 is a cross sectional view of the mold shown in FIG. 8 and taken along the line 14-14 thereof.
  • FIGS. 5a to 5c of the drawings there is shown a fragmentary length of slide fastener chain of the continuous filament type which is generally supplied to the operator for attaching slide fasener stops and sliders thereto.
  • Each length of slide fastener chain consists of a pair of continuous length stringer tapes and 22, each having a continuous length of coiled filament 24 secured to their opposed edges by stitching forming beaded edges 26 and 28, respectively.
  • the convolutions of coiled filament 24 provide a. continuous series of spaced-apart interlocking fastener elements 30 attached to the opposed edges of tapes 20 and 22.
  • a short length of coiled filament 24 is removed from along each of the opposed edges to provide a gap space G between groups of fastener elements.
  • the step of removing this short length of coiled filament is well known in the art and is generally referred to as the gapping operation with the slide fastener chain resulting therefrom being known as gapped chain.
  • the gapped chain is moved to a first station as shown in FIG. 5b wherein at one end of the gap space G a substantially square shaped scrap portion is removed from each of the tapes and 22 to define a substantially square shaped opening 31 located in tapes 20 and 22 adjacent to beaded edges 26 and 28, respectively. Beaded edges 26 and 28, as shown in FIG. 5b can also be removed on one side of openings 31, if desired.
  • This operation is generally known as clicking and can be performed on the tape simultaneously with the gapping operation.
  • the step of clicking is a preferred step and not an essential step in the manufacture described hereinbelow.
  • a slider 32 is assembled to the continuous filament slide fastener chain at that end of the gap space G opposite from that end which contains openings 31, after which slider 32 can engage and disengage the fastener elements in a well known manner.
  • Suitable end stops 33 are applied to the stitched edges of tapes 20 and 22 to prevent slider 32 from being moved into the gap space G and becoming disengaged from the tapes and thus inoperative. End stops 33 will become the top stops of the finished separating end connected slide fastener of the coiled filament type.
  • the gapped slide fastener chain is moved to the next station wherein the slide fastener chain adjacent the gapped space is separated and retainer 34, which includes track extension 36 and track guide 38, and pin member 40, which includes pin guide 41, are simultaneously formed on the opposed stitched edges of tapes 20 and 22, respectively.
  • the separated tapes 20 and 22 are properly positioned within a separable injection mold, as shown in FIGS. 8 through 14, and which will be described in greater detail hereinbelow, such that openings 31 adjacent stitched edges 26 and 23 of tapes 20 and 22, respectively, are properly positioned therein to accept a quantity of thermoplastic material which will form the reenforced tape ends and separating end connection of the present invention.
  • the thermoplastic material is thermally compatible with the continuous filament type of chain.
  • the mold is then closed about tapes 20 and 22 such that the facing surfaces of the mold, which are suitably contoured, will form a cavity therein for permitting thermoplastic material in a fluid state to flow through given passageways and about both sides of tapes 20 and 22 to form retainer 34, pin member 40 and reenforced tape ends 42 and 44. Because it is necessary to form given longitudinal grooves and openings in the retainer, a pair of cores 70 and 72, as shown in FIGS. 9 through 12, are then moved into operable positioin relative to each other within the mold, after which fluid thermoplastic material is injected therein.
  • the cores 70 and 72 are then laterally displaced relative to each other and moved to their inoperative position to clear the retainer and the mold is opened.
  • a sprue 46 and scrap portion 48 of the thermoplastic material, tainer 34 then joins together the opposed tapes. This which is located intermediate pin member 40 and reassembly is moved to the next station wherein the scrap portion 43 including sprue 46 is then cut away from pin member 40 and retainer 34 and the slide fastener is severed from the continuous chain by cutting along the edge of the reenforced end members 42 and 44 resulting in a separating end slide fastener, as shown in FIG. 52.
  • Pin member 40 can then be inserted into retainer 34 and because of the well known self-heating qualities of a coiled filament fastener type of slide fastener, slider 32 can be moved to its bottomrnost position and then to its topmost position to interengage fastener elements 30.
  • the same process for forming a thermoplastic separating end slide fastener can be performed, except that the steps of the manufacture are of a different sequence in that two tapes of the metal chain are separated after the pin and retainer members are formed on the tapes and then a slider is mounted on the tape carrying the retainer 34. End stops 33 are then applied to each of the tapes before pin member 40 is inserted through the channel of slider 32 into retainer 34.
  • FIGS. 8 through 14 The suitably contoured facing surface of the lower and upper molds 5t ⁇ and 52 are shown in detail in FIGS. 13 and 14, respectively, wherein the facing surfaces of the molds are suitably contoured so that when they are placed together, fluid thermoplastic material can be injected into the cavity formed therebetween.
  • Lower mold is supported on the base of a molding press (not shown) and contains a pair of spacedapart cavities 53 and 54 formed in the surface thereof which will shape the fluid thermoplastic materialinto the outside configuration of one half of the reenforced ends 42 and 44, retainer 34 and pin member 40.
  • pin member 40 and retainer 34 each communicatewith centrally disposed runners 55 and 56 therein which in turn communicates with the sprue hole 57 formed in upper mold 52 and partially extending into lower mold 50.
  • a pair of pins 58 located in pin member cavity 54 and a pin 59 located in the track extension portion of the retainer cavity 53 will engage the stitched edge of their respective tapes 20 and 22.
  • a cooperating pair of pins 60 in the pin member cavity 62 and a cooperating pin 64 in the retainer member cavity 66 will engage the beaded edges 26 and 28 of stringer tapes 20 and 22 to support each tape in a position intermediate the contoured facing surfaces of molds 50 and 52 so that thermoplastic material injected into the mold will flow about both surfaces of tapes 20 and 22. If beaded edges 26 and 28 have previously been removed on one side of openings 31, then solid thermoplastic retainer 34 and pin member 40 will be formed on tapes 20 and 22, respectively, substantially in alignment with the fastener elements located thereon.
  • Lower mold 59 also includes a movable tape slot core 70 and a movable retainer core 72 such that when the separated stringer tapes 2%) and 22 are properly posi.ioned within lower mold 5t), and upper mold 52 is moved into operative relation relative to lower mold 50, cores 70 and 72 can be moved laterally into slidable engagement with each other. It should also be noted that those portions of the cavities forming the reenforced tape ends located in both the upper and lower molds, support the end portions of tapes 20 and 22 in a manner such that identical ribs are formed on opposite sides of the tape and that portion of the tape intermediate the rib members will be impregnated with thermoplastic material.
  • Tape slot core 70 is an elongated rectangular member which has at its outermost tip a centrally disposed relatively thin rectangular projection 74 located thereon.
  • a shoulder 76 is located on each side of projection 74, each shoulder 76 of which is beveled at one end and extends towards the base portion of core 70.

  • the undercut portions 80 of retainer core 7 will form track guide 38 in track extension 36 of retainer 34.
  • Each of the upper corners of the base portion 82 of core 72 are cut out to form substantially cubically shaped recesses 84.
  • tape slot core 70 and retainer core 72 are laterally moved within the mold towards each other to their operative condition wherein a portion of the innermost side wall 79 of projection 78 on tape slot core 70 slidably engages the side wall of rectangular projection 74 of retainer core 72.
  • Thermoplastic material is then injected through sprue hole 57 in upper mold 52 into the cavity formed between lower mold 50 and upper mold 52, flows through runners 55 and 56, to the cavity 54 for forming pin member 40 and its reenforced tape end 42, and to the cavity 53 for forming retainer 34 and its reenforced tape end 44.
  • the upper mold 52 can be displaced relative to lower mold 50.
  • Tags slot core 70 and retainer core 72 are laterally displaced within the lower mold 50 and moved to their inoperative posi tion so as to separate them, after which stringer tapes 20 and 22 with their respective formed pin member 40 and retainer member 34 located thereon, can be removed from the lower mold 5G and moved to the next station wherein scrap portion 48 can be severed therefrom.
  • the tape as it is removed from the mold is substantially as is shown in FIG. 5d.
