Abstract: A slide fastener comprises two continuous plastic filaments (synthetic-resin monofilament), each with a multiplicity of generally helicoidal coupling elements for interlocking with the coupling elements of the opposite filament, each filament being woven integral with the threads of its respective support tape to form a tape-like unit. Each coupling element has a coupling head on a loop end and a pair of shanks terminating in bight portions which connect elements of the same tape-like unit. The shanks of each coupling element, which separate the bights from the loops, are held in close abutment by warp threads, with or without weft threads which pass over and under the successive paired abutting shanks of adjacent elements. Even stronger bracing can be obtained with bulbous projections on the shanks and bights, and by extending the coupling elements the entire width of the tape-like unit, replacing all or part of the weft threads.

Abstract: A slide fastener comprises two continuous plastic filaments, each with a multiplicity of helicoidal coupling elements for interlocking with the elements of the opposite filament, each filament being woven integral with the threads of its respective support tape to form a single tape-like unit. Each coupling element has a coupling head on a loop end and a long shank and a short shank extending from opposite sides of the loop end. The long shank terminates in a first bight portion connecting it with a long shank of one adjacent coupling element, while the short shank terminates in a second bight portion connecting it with a short shank of another adjacent coupling element. The coupling elements are arranged in rows of mirror-image pairs, each including two long shanks and two short shanks. Warp threads are interwoven with the coupling elements, with even stronger bracing possible with bulbous projections on the long shanks, short shanks, first bight portions or second bight portions using textile weft threads.

Abstract: A slide-fastener stringer comprises, for each slide-fastener half, a support tape formed with a sewing strip and a facing strip, both having warp threads and a base weft thread extending all across both strips while a binding weft thread extends all across the sewing strip while engaging with reverse loops, the continuous coupling element which can be formed of a synthetic-resin monofilament. The monofilament may be of the helical-coil type in which each turn of the coil is formed with a coupling head adapted to fit between the coupling heads of an opposing coupling element, limbs or shanks connected to the head and connecting portions or bights connecting a limb of one head to a limb of the next head. The limbs against the support tape are provided with transverse grooves receiving an insertion thread which is woven into the tape.

Abstract: A slide-fastener element of the monofilamentary-coil type is held in position on a stringer tape, woven from a set of warp threads and a continuous weft thread, by a core traversing the turns of the coil, the core being anchored to the tape by the weft thread which is interwoven with a first set of ancillary warp threads above the coil and with a second set of ancillary warp threads below the coil.

Abstract: A method and apparatus for weaving a continuous fabric having parallel selvedges, including a doubleheaded needle being passed from one side of the shed to the other transversely, forming a weft double pick alternately from one side and the other. The apparatus includes an oscillating shaft moving a pair of arms supporting gripper means adapted to grip the needle on either side of the shed as the needle is being passed through the shed.

Abstract: A slide-fastener element of the monofilamentary-coil type rests on a stringer tape whose main portion lies in a plane offset from the midplane of the coil. The tape, woven from a set of main warp threads and a continuous weft thread, is anchored to the coil by two sets of ancillary warp threads which respectively overlie and underlie a core traversing the turns of the coil and are interlinked by the same weft thread, the latter also passing around the core. The underlying ancillary warp threads are coplanar with the main warp threads; the overlying ancillary warp threads are more numerous than the underlying ones and envelop about half the coil from above.

Abstract: A beadless woven slide fastener has a pair of stringers each with convolutions of a coil of filamentary material attached to a woven carrier tape wherein the tape adjacent the coil is reduced in thickness to accommodate the flanges of a slider.

Abstract: A loom for weaving a slide fastener element to a tape, the loom weaving two tapes, and a slide fastener element to each tape, simultaneously. The slide-fastener element is fed along with the warp ends to the weaving area, and undergoes simultaneous shedding movement with the warp ends. The filling needle is driven in an elliptical path through each successive warp shed. The eye of the needle, through which the filling passes, moves closely adjacent to the weaving point in the first half of its path and then moves distantly away from the weaving point in the second half of its path. Each pick of the filling thereby catches and binds the slide-fastener element at a location immediately adjacent to the weaving point.

Abstract: A helical series of slide fastener links is fed parallel to warp threads and the filling threads are inserted to weave the tape. The helical or meandering series of slide fastener links is extended adjacent to the zero plane of the weaving machine and is moved along a straight line and without formation of a shed during the weaving operation. At least two joining warp threads are warped which are spaced from the series of slide fastener links and disposed before the coupling surfaces thereof. Warp threads of the backing woven fabric are warped on the other side of the series of slide fastener links. Two joining warp threads lying in upper and lower sheds are formed into a first shed. The warp threads of the backing woven fabric and any remaining joining warp threads lying in a middle shed and the lower shed are formed into a second shed.

Abstract: A tape stringer for a sliding clasp fastener having a web section and a woven filament section forming an end section of a tape. Both the web and the woven filament sections include a plurality of warp threads interwoven with a continuous weft thread and the woven filament section includes a spiral-shaped continuous plastic filament woven into the filament section. The spiral-shaped continuous plastic filament forms a row of connected together loops having coupling heads projecting beyond the end of the tape and having limbs that are inserted in and secured to the end section of the tape by the warp threads which engage the limbs along substantially their entire length.

Abstract: A carrier tape for sliding clasp fasteners is provided which comprises a weave foundation consisting of warp and weft threads made of filamentary plastics material, and a plurality of inlaid threads interwoven into the foundation and extending longitudinally in parallel with the warp threads. The inlaid threads are greater in denier than the foundation threads and form a multiplicity of ridges which project from and above at least one surface of the foundation and which are spaced longitudinally apart by a predetermined pitch.

Abstract: This method and the apparatus for carrying out same are characterised essentially in that, during the weaving of the tape of the element, two separate filaments are inserted into the texture for constituting the fastening or coupling members propers by engaging by turns one and the other filaments between the warp yarns, at spaced intervals, to constitute at each point of insertion a transverse loop wound in one direction for one filament and in the opposite directions for the other filament, and meanwhile these filaments are disposed in the longitudinal direction on the side opposite to the coupling members proper, whereby these filaments constitute two variable-pitch helices of which the loops wound in opposite directions are imbricated, every other loop belonging to the same helix.

Abstract: A method of manufacturing slide fastener stringers having a row of continuous coupling elements which is spirally coiled and woven into the fabric tape simultaneously with the weaving of the latter. There is provided a shuttle for carrying an element-forming filament which is interwoven with warp yarns forming the tape edge and looped over a mandrel wire located adjacent the tape edge by reciprocal, transverse movement of the shuttle. The shuttle is rotated about its central axis during one cycle of the reciprocal movement thereof to eliminate a twist or torsion on the filament imparted by the shuttle reciprocally passing alternately over and under the mandrel wire.

Abstract: A method of making a woven zipper is disclosed, and an apparatus for carrying out the method.A zipper tape is woven from warp threads and weft threads. A coil-forming filament is advanced longitudinally of the weft threads and additionally is made to perform a movement about the surface of an imaginary cone whose base extends transverse to the longitudinal advancement of the filament. Cover threads, extending lengthwise of the weft threads are stepwise moved to the vicinity of the imaginary surface and held until the filament has passed them; thereupon, they are moved through the surface to the interior of the cone and a binding thread is passed behind them in longitudinal direction of the weft threads.
