摘要:
A water-tight slide fastener is disclosed, which comprises a pair of support tapes each coated on one surface with a water-resistant material and a row of coupling elements mounted on each of the tapes along its longitudinal edge. The spaces or gaps defined in the row of elements being completely filled by a filling core when the latter swells in contact with a liquid to prevent entry of the liquid into a garment to which the fastener is applied.

A stringer for a slide fastener has a coupling element formed from a continuous filament with leg portions secured to a tape-like portion wherein an elongated member is interposed between the superimposed leg portions. The leg portions are provided with grooves, teeth, or the like, for interlocking with the elongated member to restrain longitudinal and transverse movement of the leg portions relative to the elongated member. The elongated member provides dimensional stability to the coupling element.

A reinforcement is provided for reinforcing a longitudinal edge of a stringer tape for a slide fastener, which reinforcement consists of an elongate core member and a tubular member holding the former centrally in place. The tubular member is a warp-knitted fabric formed by a Raschel or tricot double-needle knitting machine, the fabric having sinker loops interconnected with corresponding needle loops and urging the latter into fastening engagement with the core member.

A stringer for a slide fastener has a continuous filamentary coupling element attached to an edge of a tape with a pair of spaced elongated members, such as textile cords, interposed between and secured to leg portions of each section of the coupling element. The spaced pair of elongated members provide stability to the continuous coupling element.
摘要:
A continuous coupling element consists of an elongated filament of a synthetic resin or the like which is wound substantially helically to provide a multiplicity of turns with a row of spaced apart coupling heads formed along one longitudinal side thereof. Each of the turns further includes first and second shanks which when seen in a plan view, are curved arcuately in opposite directions, in such a manner that the first shanks of the respective turns partly overlap the second shanks of the preceding (or succeeding) turns and are connected to the second shanks of the succeeding (or preceding) turns via arcuate bights remote from the coupling heads. The continuous coupling element is to be fastened to one surface of a stringer tape as by a row of stitches extending along the overlapping portions of the first and second shanks.

A waterproof slide type fastener or zipper assembly featuring side by side tape means the adjacent edges of which mount cooperatively designed interlocking loops or coils wherein the tapes and loops are coated and filled with a resilient material in the nature of a room temperature vulcanizable silicone rubber compound. The arrangement is such that the interlocking of the loops on the respectively adjacent edges of the tapes, through the medium of a slide type closure element, causes a compression and sealing adherence of the contained resilient material which forms a releasable but positive seal and bond between the parts. The energy stored in the compression of the resilient material insures against passage of water in the vicinity of the interlocking loops while permitting their ready separation, as and when required. The invention also contemplates a simple and inexpensive way of using vacuum to apply the resilient material to the loops or coils and their connected tapes.

A slide-fastener stringer has its turns (of continuous coil or meander coupling element) secured to its fabric support tapes by means of single-needle or double-needle double chain-stitch or lockstitch wherein bights of the needle thread straddle the coil turns and pass through the filler cords. The U-shaped bights of the needle-thread loops of each stringer half snugly embrace the individual turns and this thread is so tensioned that the looper or gripper thread lies completely along the opposite face of the support tape. The support tape is formed parallel to at least one of its longitudinal edges with a longitudinally extending valley or channel in which the looper, locking or gripper thread lies. In addition the upper side of the coil is formed with a longitudinally extending groove (formed by notches in the shanks of the turns) in which the needle thread lies. After stitching of the interleaved coils to the tapes the thermoplastic monofilament needle thread which has been stretched, is heated to thermally fix and shrink it.

The invention provides a process, for the manufacture of a continuous chain of two rows of linking components for the making of slide fasteners out of two rows each consisting of a thread shaped into a spiral inside the whorls of which a longitudinal cord or strand is positioned, the improvement that the said cord or strand is placed in an intermediate position in the width of each row by assembling the two corresponding rows while causing the linking components of each row to penetrate more deeply between the whorls of the other, in order to push back the length-ways inside cord or strand in the latter row, whereafter these two rows are fixed on to two supporting tapes by means of lines of stitching, the stitches of said lines being inserted inside the free spaces between the cord or strand inside each row and the portions connecting the successive whorls thereof.
摘要:
A sliding clasp fastener of flexible concealed fashion including a row of elements on each stringer tape, said element having a recess at least in one of its two leg portions for anchoring sewing threads. The sewing threads interconnect the flexible elements to the stringer tape in such a manner that the flexible elements are maintained in a normally flexed condition.
