Definitions

  • ABSTRACT 24/205'16 C Slide fastener chains having a filamentary stringer with 58 i 205 13 C a plurality of head elements interconnected to a plu- 1 0 earc 5 13 rality of generally U-shaped heel members are formed by disposing stringers along a longitudinal edge of carrier tapes with the heel memlbers threadlessly bonded
  • the present invention pertains to slide fastener chains and more particularly to threadless slide fastener chains wherein the stringers are directly bonded with the carrier tapes.
  • Numerous slide fasteners utilize coupling elements of the type formed from a continuous length of filamentary material which has been deformed into a series of head elements interconnected to first and second sets of generally U-shaped heel members by a plurality of legs.
  • a continuous filamentary stringer is com monly referred to as a ladder-type stringer and may be manufactured from any suitable plastic material which, after being formed, can be conveniently attached to a carrier tape.
  • the stringer is disposed with the head elements aligned next to a longitudinal edge of a carrier tape with the plurality of legs and the first and second sets of heel members overlying respective opposite surfaces of the tape.
  • the plurality of legs of the filamentary stringer are thereafter attached to the carrier tape by suitable stitching or braiding which typically passes through the carrier tapes and around the exposed outer surface of each of the legs to securely affix the stringer to the tape in such a position that the protruding head elements from a pair of filamentary stringers may be easily interengaged for effectively joining a pair of carrier tapes.
  • the resulting interengaged article which is commonly referred to as slide fastener chain, is then processed through a series of subsequent operations to produce individual finished slide fasteners of a given size or length.
  • Slide fasteners of the type just described have proven to be highly satisfactory under various conditions of use and as a result have received widespread commercial acceptance.
  • such slide fasteners are exposed to considerable surface abrasion on both inner and outer surfaces thereof which has a tendency to sever, tear or otherwise damage the exposed stitching threads.
  • abrasion of the stitching threads tends to free the stringers from the tapes which often results in misalignment of the interengagable head elements and can cause the slide fastener to jam or to undesirably open at the point of thread wear.
  • the present invention has a further object to provide a method of securely attaching heel members of a filamentary stringer to a carrier tape without stitching threads or braiding thus producing a threadless slide fastener chain.
  • Another object of the present invention is to ultrasonically fuse the heel members of a filamentary stringer with a carrier tape to form a threadless slide fastener chain.
  • the present invention has an additional object in the construction of a threadless slide fastener chain wherein portions of a carrier tape are displaced into the interstices of a filamentary stringer and are rigidly bonded thereto to form a chain with improved wear characteristics.
  • a further object of this invention is to attach a filamentary stringer to a carrier tape by bonding superimposed filamentary stringer portions to each other through a carrier tape.
  • a threadless slide fastener chain includes a carrier tape, a filamentary stringer having a plurality of head elements interconnected to a plurality of generally U- shaped upper and lower heel members by a plurality of legs, the filamentary stringer being disposed along a longitudinal edge of the carrier tape with the plurality of legs and the upper and lower heel members overlying respective opposite surfaces of the carrier tape, and each of the upper and lower heel members being threadlessly bonded with the carrier tape whereby the filamentary stringer is firmly attached to the carrier tape.
  • FIG. 1 is a partial plan view of an embodiment of a threadless slide fastener chain. according to the present invention.
  • FIG. 2 is a partial sectional view taken on line 22 of FIG. 1;
  • FIG. 3 is a partial cross-section taken on line 3-3 of FIG. 1;
  • FIG. 4 is a partial plan view of a second embodiment of a threadless slide fastener chain according to the present invention.
  • FIG. 5 is a partial sectional. view taken online 55 of FIG. 4;
  • FIG. 6 is a partial cross-section taken on line 66 of FIG. 4.
  • the present invention is embodied in a threadless slide fastener chain, indicated generally at 10, having a pair of carrier tapes l2 and 13 upon which are disposed a respective one of a pair of filamentary stringers 14 and 15.
  • the filamentary stringers 14 and 15 are substantially identical and are each preferably formed from a continuous length of plastic filamentary material which has been deformed into a series of head elements 16-17 interconnected to first and second sets of generally U-shaped heel members 18-19 and 20-21, respectively, by first and second sets of generally straight legs or leg portions 22-23 and 24-25, respectively.
  • the filamentary stringers l4 are each disposed along a longitudinal edge of one of carrier tapes 12 and 13 with the first and second sets of legs and the first and second sets of heel members overlying respective opposite sides or surfaces of the carrier tapes as illustrated in FIGS. 2 and 3.
  • the stringers thus straddle the edge of the carrier tapes with the head elements 16 and 17 aligned in parallel relationship with such edge whereupon they may be easily interengaged as shown in FIG. 1.
  • the carrier tapes 12 and 13 are generally flat except at their inner longitudinal edges where they are each displaced upwardly and downwardly at spaced points along the edge to conform to the interstices defined by each of the U-shaped upper and lower heel members 18-19 and 20-21, respectively, and the straight legs 22-23 and 24-25.
  • the edge of the carrier tape is thus convoluted or sinuous as can be visualized in FIG. 2 with each displaced portion of the tape forming an arcuate raised surface conforming precisely to the interstitial dimensions of the legs and heel members of the stringers.
  • the carrier tapes may take any number of forms depending upon the particular contemplated application of the finished slide fasteners.
  • such tapes may be woven or sewn flat and subsequently deformed, either prior to assembly with the stringers or concurrent therewith, or may be woven to assume its distorted edge shape without requiring a subsequent displacing step.
  • the tapes may also be of the nonwoven type wherein the various fibers used therein are bonded or fused together to form flat strips of material in accordance with any number of well known manufacturing techniques.
  • Each of the filamentary stringers are attached to the carrier tape in its displaced shape by directly bonding the generally U-shaped heel members of the stringer to the arcuate raised surface of the carrier tape with the fused portion 26 being diagrammatically illustrated in the drawings. It can be seen that by directly bonding the stringers with the carrier tape, the slide fastener chain requires no stitching threads and is thus capable of withstanding considerable surface abrasion which would otherwise sever or tear the stitching employed in conventional slide fastener chains.
  • Such bonding may be accomplished by any of a number of techniques including, for example, the use of adhesives, dielectric heating, irradiation or ultrasonic fusing. If ultrasonic fusing, for example, is employed to produce the bond, the filamentary stringers as well as the carrier tapes are preferably constructed so as to contain a suitable thermoplastic or fusible material. The ultrasonic energy is thereafter directed through the U-shaped heel members of the stringer and the carrier tape such that a bond of sufficient strength will be formed at the area of contact between the tape and the stringer to assure positive attachment therebetween. It is noted that the strength of such bond is enhanced by the convoluted or arcuately raised surface of the tape which provides a relatively large surface area of contact between the tape and the heel members of the stringer. Furthermore, the raised surfaces of the tapes become rigidized during bonding whereupon the vertically displaced interstitial portions of the carrier tape act as abutments which tend to prevent separation of the tape from the stringer when subjected to lateral disruptive forces.
  • the carrier tapes may be of any suitable type such as a nonwoven material.
  • Such nonwoven carrier tapes have an inherently high degree of elasticity which makes them especially well suited for use in the threadless slide fastener chain according to the present invention. This is primarily due to the fact that the elasticity of the nonwoven tape permits the tape to deform somewhat under the force of a point load applied to one of the head elements of the stringer; as a result, the point load is distributed to adjacent elements whereupon it can be absorbed without causing damage to the slide fastener chain.
  • FIGS. 4-6 there is illustrated a second embodiment of a threadless slide fastener chain according to the present invention.
  • the threadless slide fastener chain of FIGS. 4-6 is similar to that of FIGS. 1-3 and identical numerals with added thereto will be used to describe correspondingly similar structure.
  • the threadless slide fastener chain of FIGS. 4-6 has a pair of initially substantially flat carrier tapes 1 12 and 113 upon which are disposed a respective one of a pair of filamentary stringers 114 and 115.
  • the filamentary stringers 114 and 115 are substantially identical and are each preferably formed from a continuous length of plastic filamentary material which has been deformed into a series of head elements 116-117 interconnected to first and second sets of generally U- shaped heel members 118-119 and 120-121, respectively, by first and second sets of generally straight legs 122-123 and 124-125, respectively.
  • the filamentary stringers 114 and 115 are each disposed along a longitudinal edge of one of carrier tapes 112 and 113 with the first and second sets of legs and the first and second sets of heel members overlying respective opposite surfaces of the carrier tapes as illustrated in FIGS. 5 and 6.
  • the stringers thus straddle the edge of the carrier tapes with the head elements 116 and 117 aligned in parallel relationship with such edge whereupon they may be easily interengaged as shown in FIG. 4.
  • the carrier tapes 112 and 113 each define a set of spaced holes -131 therethrough which are aligned in parallel relationship with the longitudinal edge of the tape. Each of the holes are cut through the tape in such a position as to be interposed between an end of adjacent upper and lower heel members 118-119 and 120-121, respectively.
  • the carrier tapes are initially not displaced or convoluted as in the preceeding embodiment but are generally flat throughout. The filamentary stringers are then placed on the tapes so as to straddle the perforated edge of the tape with the ends of the U-shaped heel members aligned with the holes. The heel members are thereafter held together with the ends of adjacent heel members in contact as illustrated in FIGS.
  • the particular carrier tape employed in the slide fastener chain of FIGS. 4-6 may be either woven or nonwoven and may or may not contain thermoplastic or other fibers depending upon the contemplated use of the finished slide fastener.
  • the tapes are distorted, as in the previous embodiment, in order to provide a larger bonding surface between the stringers and tapes.
  • threadless slide fastener chains according to the present invention are simple in construction, are economical to manufacture, do not require the use of stitching threads, braiding, or the like, and effectively withstand a degree of surface abrasion which would otherwise produce undesired tearing of conventionally employed stitching threads and resultant premature failure thereof.
