A warp-knit support tape for hook and loop fasteners comprises a pile portion including a foundation of tricot stitches and single cord stitches and a multiplicity of pile-loops formed from chain stitches. The tricot and single cord stitches are formed of crimped yarns, and there is additionally laid in a plurality of warp members made of an elastic material to allow the tape to stretch particularly in its longitudinal direction.

A velvet-type or snap-together fastener web comprises a warp-knitted ground structure and series of interlooped loops disposed in at least every other wale, each loop including a pair of mushroomed stems projecting from the wale at each course. To produce such a fastener web, a double-faced fabric is knitted on a Raschel warp knitting machine, and is separated into a plurality of strips by dissolving transversely spaced water-soluble threads in the fabric. Each strip is divided into front and back fabric webs by severing thermoplastic thread portions therebetween, leaving a multiplicity of raised stems on each fabric web. The raised fabrc stems are then heated to mushroom their ends.

A wrap-knit stringer tape for slide fastener comprising a warp-knit structure including a coarse region extending longitudinally therethrough within a portion other than a coupling element-supporting marginal edge portion, said coarse region being devoid of at least one of the threads which are knit in a wale-forming stitch pattern and each interconnecting two adjacent wales.

A slide fastener stringer includes a warp-knit stringer tape comprising a first set of yarns forming a knit ground structure containing stitch loops in every course and wale of the tape, and a second set of yarns knit in the ground structure and each extending coursewise across at least one wale, the yarns of second set comprising textured yarns. A third set of yarns forms a plurality of chains of loops knit in the ground structure and extending along wales in at least one edge portion of the tape. A fourth set of yarns is laid in the ground structure and extends in and along the wales in the tape edge portion, on which a row of coupling elements is mounted. With the stringer tape thus constructed, the tape edge portion is tight and resistant to walewise stretch and the remainder portion is relatively coarse and roughened.

A slide fastener stringer includes a stringer tape of a warp-knit structure and a series of discrete or separate fastener elements mounted on and along one longitudinal edge of the stringer tape. The stringer tape has a reinforcing cord laid therein or inserted in an outermost groove between adjacent two wales of the tape, the cord extending warpwise and being thicker than the threads forming the tape fabric. The reinforcing cord is stitched with lock or double locked stitches at intervals spaced along the tape, thereby providing an element-anchoring bead on the tape. A pair of additional threads are preferably interlaced with the stitches and are disposed on the flat surface of the tape.
摘要:
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.
摘要:
A warp-knitted tape for slide fasteners is provided with a web portion and a marginal edge portion extending longitudinally thereof and connected together integrally with a combination of different stitches. The marginal edge portion has two adjacent wales spaced one wale pitch apart to provide thread-free regions for unrestricted passage of sewing needles.
摘要:
A warp-knit tape structure is disclosed for use as a carrier tape for mounting thereon a row of fastener elements. The carrier tape has a web portion and adjoining marginal edge portion extending one longitudinal edge of the tape, said edge portion having a relatively wide interwale groove for the passage of a sewing machine needle and a plurality of wales adjacent to said interwale groove held closely together to provide a reinforced region disposed for sliding contact with a slider of the slide fastener.

In a content addressable memory device, before search operations in two TCAM cells connected to first and second match lines, respectively, a memory controller connects the first match line to a power source and connects the second match line to a ground, and then connects the first and second match lines to each other so as that electric potentials of the first and second match lines are the same as each other.

A design support apparatus supports wiring design for bond wires that connect a semiconductor chip and an interposer. The design support apparatus includes a creating unit that creates simulated design data simulating occurrence of fluctuation in an arrangement position of a semiconductor chip on an interposer and occurrence of fluctuation in bond wire connection terminal positions of the interposer, and an analyzing unit that analyzes, based on the simulated design data, deficiencies in manufacturing of semiconductor devices due to the fluctuation in the arrangement position of the semiconductor chip on the interposer and the fluctuation in the bond wire connection terminal positions of the interposer.
