An ornamental slide fastener comprises a pair of stringer tapes each having an upper strip and a lower strip interconnected by a rib about which the tape is folded, a row of coupling elements secured to the lower strip, the two strips defining therebetween a guide channel for receiving a slider and a series of ornaments applied to the upper strip end extending into the region of the rib so that continuity of the ornaments is maintained against the influence of lateral pull tending to spread the two tapes apart.

A stretchable slide fastener includes a pair of stretchable stringer tapes each having a longitudinal edge, and a row of coupling elements mounted on the longitudinal edge at a pitch. The pitch of the row of coupling elements is variable as the longitudinal edge is stretched. Each of the coupling elements includes a coupling head having a height, and at least the longitudinal edge being longitudinally stretchable by at least 10% such that the pitch of the coupling elements remains smaller than an interval which is twice the height of the coupling head.

Stretchable slide fastener

In washing an elongated tape with hot water, the tape is fed through a succession of hot-water baths one after another. When the tape is transferred from one bath to the next, the hot water on and in the tape is removed. In each bath, the tape is brought out of and then into the hot water at least one time.

Method and apparatus for washing elongated tape with hot water

A fluid-tight slide fastener stringer has a fluid-tight tape including a longitudinally non-stretchable and transversely stretchable woven or knit fabric wholly covered with a layer of elastic rubber or synthetic resin. The tape has non-stretchable warp inlaid threads and stretchable weft inlaid threads. The laterally stretchable tape serves as a shock absorber for reducing the intensity of external lateral pulling forces exerted on the tape.

Fluid-tight slide fastener stringer

A fluid-tight slide fastener stringer has a fluid-tight tape chiefly made of rubber or synthetic resin on which tape a series of discrete coupling elements are supported along an inner longitudinal margin of the tape. The tape margin is folded so as to provide therealong a pair of spaced contact portions and a folded edge portion disposed between the contact portions. The tape has a foamed layer extending in and through at least the contact portions and the folded edge portion. At least the margin of the resultant tape is excellent in ability of restitution, causing an improved fluid-tightness between the opposed stringers.

An apparatus capable of simultaneously coating one side of each of several surface type fastener tapes or the like traveling longitudinally in coplanar, parallel spaced relation to one another. For simultaneously coating two fastener tapes a pair of terminal coating units and one intermediate coating unit are arranged alternately with the fastener tapes. Each fastener tape travels with its opposite longitudinal edge portions slidably engaged in recessed guideways defined in the terminal and intermediate coating units. A coating material is supplied through passageways in the coating units onto the surfaces of the fastener tapes traveling therebetween. Mounted to the coating units so as to extend across the fastener tapes, a doctor blade has its scraping edge held against the surfaces of the tapes. The fastener tape guideways in the coating units all decline from their upstream toward downstream ends with respect to the traveling direction of the tapes, so that the coating material collects in the spaces bounded by the tapes, coating units and doctor blade. The doctor blade creates a coating of constant thickness on each fastener tape as the latter travels therepast.

Apparatus for coating one side of one or more surface type fastener

An improved loop-forming assembly in a weaving machine for forming a surface fastener tape blank having a multiplicity of warp pile loops formed of loop-forming warp threads comprises: a plurality of parallel spaced lancets; a deflector extending transversely of and over the lancets; and a plurality of pairs of parallel spaced gate hook bars; the lancets, the deflector and the gate hook bars being kept free from one another. The deflector is axially reciprocable for laterally deflecting the threads in eyelets with respect to the lancets, respectively, and the gate hook bars are vertically reciprocable in timed relation to the deflector to lower the thus deflected threads by hook portions alternately at one side and then at the other side of the lancets so as to pass the threads over the lancets in a staggering fashion to form the warp pile loops.

Loop-forming assembly for weaving machine

A woven slide fastener stringer comprises a row of filamentary coupling elements fastened to a stringer tape by a binding thread system composed of weft and warp threads intertwined with the coupling elements and the stringer tape. At least a pair of warp threads symmetrically overlie and underlie upper and lower legs of the coupling elements and cross each other between adjacent coupling elements. The weft threads of the binding thread system are interlooped with the symmetrically running warp threads at the upper and lower legs of the coupling elements. With such an arrangement, coupling heads connected to the coupling element legs are disposed substantially perpendicularly to the plane of the stringer tape for increased coupling strength necessary to keep opposite rows of coupling elements securely interengaged against accidental separation. An apparatus for manufacturing such a woven slide fastener stringer includes independent heddles and filling inserters for supplying warp and weft threads of such a binding thread system.

A woven slide fastener stringer comprising a stringer tape woven of warp and weft yarns and a row of fastener coupling elements in the form of a coiled or zigzag-shaped filament woven into the stringer tape along a longitudinal edge thereof. The stringer tape includes a first marginal portion adjacent to the fastener-element-supporting tape edge, a second marginal portion adjacent to the other longitudinal tape edge, and an intermediate portion extending between the first and second marginal portions, the intermediate portion having a woven structure coarser and thicker than that of the first marginal portion. The number of interlacings of the warp and weft yarns per unit area in the intermediate tape portion is smaller than that in the first marginal tape portion.

A woven fastener stringer for slide fasteners comprises a woven tape formed with foundation warp and weft threads and consisting of a web section defining a major dimension of the tape and a woven filament section defining a longitudinal edge portion of the tape, a row of successively interconnected elongated loops woven into the filament section, a plurality of covering warp threads overlying and underlying the loops, a stuffing cord extending longitudinally of the tape through the row of loops, at least one guide cord extending longitudinally of the tape in abutting engagement with the outer surfaces of heel portions of the loops, a binding weft thread continuing from the foundation and interwoven with the covering warp threads in the woven filament section, and a pair of tensioning warp threads extending longitudinally of the tape between the covering warp threads.

Woven stringer for slide fasteners

A slide fastener stringer is disclosed which has a fastener element in the form of a helical coil having a row of successive loops woven into a longitudinal edge of a stringer tape simultaneously as the tape is woven. The fastener element is held stably in position by a stuffing cord which is anchored therein by weave threads. A guide cord is arranged such that it may be deformed under tension applied by a binding thread to provide slider guide surfaces.

A slide fastener stringer is disclosed, while has a woven tape carrying a row of coupling loops which is likewise woven, instead of being stitched, into an edge of the tape. The row of loops is secured by a plurality of binding warp threads extending longitudinally of the tape and overlying the upper portion of each of successively interconnected loops. A binding weft thread, separate from the tape foundations weft, is interlaced with the binding warp threads in a plane defined commonly by the successive upper portions of the loops and interwoven with the foundation weft thread interiorly of a heel portion of the loop, thereby securing the loops firmly to the tape without any such thread behind the heel of the loop which would otherwise interfere with the movement of a slider.
