Definitions

  • My present invention relates to improved endstop members for open-end (separable) or closed slide fasteners.
  • the endstop formations which facilitate the guiding of the slider into the fastener element or which subsequently block withdrawal of the slider are integrally molded from the material of the reinforcing strip upon or concurrently with its fusion to the band.
  • the fastener elements themselves may be composed of a thermoplastic material and constituted as part of the endstop members by fusion and molding concurrently with the latter.
  • the fastener element (which may be a molecularly-riented polyamide monofilament coil in a helical configuration designed for interengagement of its turns with those of a like coil, with or without matingly engageable heads, or a train of individual and spaced-apart coupling members engageable between the corresponding members of the other slide-fastener half, or any other coupling element commonly used in the slide-fastener art) contributes synthetic-resin thermoplastic material to the moldable mass transformed into the endstop member.
  • applications Ser. Nos. 562,877 and 566,413 are directed specifically to a unique arrangement whereby the moldable ice strip also forms an end stiffener preventing unraveling of the tape, is resistant to washing in aqueous media and treatment by organic solvents, and prevents tearing of a guide portion of an endstop member from the tape upon repeated insertion of this guide portion into the slider.
  • moldable reinforcing strips of this character were produced according to prior developments by me and my coworkers, as set forth in the abovementioned applications, by juxtaposing a length of reinforcing strip (e.g., a thermoplastic foil) with a continuous slide-fastener strip and making that reinforcing strip of a length equal substantially to the width of the continuous strip. Thereafter, the length of reinforcing foil is applied to the slide-fastener band with heat and pressure over the entire breadth of the band (e.g., with a stamping and forming die and inductive heating), to bond the foil to the substrate strip and concurrently to shape endstop formations in the heated portion of the strip.
  • a length of reinforcing strip e.g., a thermoplastic foil
  • the length of reinforcing foil is applied to the slide-fastener band with heat and pressure over the entire breadth of the band (e.g., with a stamping and forming die and inductive heating), to bond the foil to the substrate strip and concurrent
  • the reinforced end of the slide fastener tends to be attached less securely to the adjoining support portion and may lead-to defects in the garment.
  • Another disadvantage appears to derive from the fact that the stiffened portions of the slide fastener have relatively sharp corners and edges and, when the slide fastener is stitched into a garment, cause scratching and irritation of the user.
  • Another object of this invention is to provide an improved slide-fastener construction whereby the endstop members may be molded at least in part from an applied reinforcing strip or foil but scratching and irritation of the user of the slide-fastener is avoided and attachment of the slide fastener to a garment or other support is facilitated.
  • the useful life of the slide fastener can be extended by improving the manner in which it is stitched to its support, when, along the edge of each tape remote from the respective coupling element in the region of the reinforcing strip, a marginal nonreinforced portion is left.
  • the stitching of the respective slide-fastener halves to their supports via these tapes is effected along these marginal portions beyond the reinforcing foil.
  • the foil corners are inwardly of the outer boundaries of the slide-fastener strip, thereby ensuring that they will not irritate the wearer of a garment to which the slide fastener is affixed.
  • thermoplastic foil of limited width when the thermoplastic foil of limited width is bonded to the slidefastener strip under heat and pressure and the endstop formations are molded from the material of the thermoplastic coupling element and/or the foils, the lateral strength of the slide-fastener halves and resistance to separation of the coupling elements and/or stop formations from the tape at the extremities of the coupling elements is approximately equal to those of slide fasteners in which the reinforcing foil spans the entire breadth of the tape.
  • FIG. 1 is a plan view showing a slide-fastener strip according to this invention,'prior to the severing thereof into individual slide-fastener lengths but subsequent to the emplacement of the reinforcing foils;
  • FIG, 2 is a cross-sectional view, somewhat enlarged taken along the line 11-11 of FIG. 1;
  • FIG. 3 is a cross-sectional view taken along the line IIIIII of FIG. 1;
  • FIG. 4 is a view similar to FIG. 1 of a modification of the invention.
  • FIGS. 1-3 of the drawing I show a slide-fastener strip generally designated 20 whose slide-fastener halves 21 and 22 are interconnected by their respective coupling elements and are passed continuously through a fusion press in which a synthetic-resin foil is applied at spacedapart locations to the continuously moving strip 20 and molded into endstop members so that the endstop members have a volume equal to the moldable resin of the foils and of the fused portions of the synthetic-resin coupling elements merged therewith.
  • the apparatus for this .4 purpose can be of the type described in applications Ser. Nos. 472,953 and 473,003 (i.e. US. Patent No. 3,353,- 256 and No. 3,340,594).
  • the slide-fastener halves 21 and 22 each have a respective textile support band or tape 1 or 2 with a respective endless coupling element 3 or 4, these elements being nterfitted as illustrated in FIG, 3.
  • suitable coupling elements include a train of spaced-apart coupling members formed from a synthetic resin having thermoplastic character, a helical coil is preferred as shown in FIGS. 1 and 3.
  • the synthetic resin of the coupling elements 3 or 4 may be of the molecularly oriented type and preferably is a molecularly reoriented polyamide or polyurethane.
  • the coupling elements 3 and 4 are joined to the respective tapes 1 or Z by conventional means here illustrated as including a weld cord or fillet 23, 24 serving as guides for the slider (not shown) and attached to the coupling elements 3, 4 and to the tapes 1, 2 by chain stitching 25, 26 (FIG. 3).
  • stiffening foils as represented by the outline 27, of generally rectangular configuration and of a length L approximately equal to one-half the width W of the strip 20.
  • the coupling members 5 and 6 on each side of the strip 20 are molded integrally from such foils 27 and can be separated by an opening 28 between the ridge-like formations 7 and 8 so that the individual members 5, 6 have widths approximating only half the width of the respective tape.
  • the longitudinal extent w of the foil 27 preferably is equal to at least one-half L for the reason indicated earlier.
  • the foils 27 above and below the strip 20 are applied as described in the aforementioned copending applications. They are thermally bonded to each other through the textile tapes 1, 2 and fused to the thermoplastic coupling elements 3, 4.
  • the thickened ridges of bulging cross-sections 7 and 8 extend along the coupling elements but are provided with lateral or transverse projections 10 and 11, extending toward the respective tapes and intercepting the slide in its extreme position.
  • these formations 10 and 11 are located at the very extremities thereof. I have found it also advantageous to simultaneously mold formations 13 from the thermoplastic coupling elements 3 and 4 above the endstop members 5 and line 12 to enable the slider to pass onto the slide-fastener halves and to serve as guide for this purpose.
  • the bands 1 and 2 at the closure end are joined together by a transverse heat weld at the level of location 13 or are sewed together by a stitch seam for this purpose; the marginal portion 17 outwardly of the foil members 5 thus remains free.
  • the width w of the band forming the endstop members 35 is greater than in the embodiment of FIG. 1 and the endstop members 37 and 38 flanking the opening 38' between the coupling elements 33 and 34 of the tapes 31 and 32 are molded from the foil as previously set forth.
  • Marginal strips 47 are again formed outwardly of the endstop members which have lateral projections 40 and 41.
  • a pair of guide ramps 14 and 15 are, however, molded integrally with the endstop members prior to separation along the line 16.
  • the outwardly divergent regions 14 and 15 thus constitute plug-like members upon one of which a socket can be mounted while the other member is insertable therein through the slider (see commonly assigned application Ser. No. 562,887).
  • the slide fastener is eifective as a separable arrangement.
  • each of said endstop members is constituted of a synthetic-resin foil of substantially uniform cross-section extending from the respective coupling element along the respective tape in thermally bonded relationship therewith while spanning about one-half the full width of the tape whereby a flexible and unencumbered marginal fabric portion having substantially half the width of said tape extends beyond each of said endstop members over the full length of the p
  • each of said endstop members has at least one formation unitarily formed from the foil and disposed along the respective coupling element for interception of a slider movable along said coupling elements;
  • said tape is at least partially imbedded in the synthetic resin of said foil all along the part of the tape spanned by the foil, the synthetic resin permeating the interstices of the fabric of the tape.
