Definitions
- a slide fastener unit having two rows of links which are secured to the two halves of the supporting tape, each of the halves being a Y-tape with the upper and lower ends of each half partly covering the row of links at each side so that adjacent upper and lower ends form parallel longitudinal bands exposing to view the middle of the rows of links at each side where these rows come together and the individual loops of the rows of links remote from the center.
- These rows of links are formed by weaving a continuous length of heavy duty thermoplastic synthetic mono-filament as a warp into the two short arms of the Y-t-ape to form loops and links in a single operation.
- the loops and the links which are initially in the same plane are heat-deformed between the free ends of the arms of the Y-tape to form U-shaped links facing towards the edge of the tape while the loops are compression set at the part of the arm remote from the edge to form a guide for the fastener slide.
- the present invention relates to a slide fastener having rows of links which are secured to the two halves of the supporting tape by weaving with high strength, synthetic mono-filament on a high-speed loom or on a conventional ribbon loom which can be manufactured in high quality and at low cost.
- the so-called woven slide fasteners which are known are formed with finished rows of links during the weaving of each of the halves of the supporting tape.
- a strong synthetic filament which is to form the row of links is introduced into each half of the supporting tape as a weft thread, twisted into the line of threads in the supporting tape and bound in.
- This method of weaving and binding can be effected only with two shuttles and only with a small number of picks. A higher number of picks cannot be successfully used because of the difiiculty in deforming the high-strength mono-filament synthetic weft thread which, because of its a stiffness, resists picking as applied in the conventional ribbon loom of high-speed loom.
- Slide fasteners are also known wherein ready made rows of links of snythetic fibers are employed, which fibers have been twisted or otherwise crimped and are 3,551,962 Patented Jan. 5, 1971 secured by being woven by special machinery during the weaving of the halves of the supporting tape.
- the short arms of the Y-tape are brought toward each other by the method of the present invention with a high-strength synthetic mono-filament which is woven on the tape itself to form the row of links and which runs backwards and forwards alternately between these two short arms.
- the high-strength synthetic mono-filament is woven into the central region of the short arm and under the free ends thereof so that the free ends of the short arms cover both sides of the links to form parallel longitudinal bands above and beneath the links.
- the synthetic filament in this specific embodiment comprises loops of heavy duty thread which are situated at the outer faces of the short arms at the side remote from the closing teeth and thereby form a guide for the fastener slide.
- the two short arms may together have the same number of picks as the long arm of the supporting tape.
- the slide fastener unit according to the invention offers the advantage, inter alia, that each row of links is covered at both sides by the short arms of the Y-tape and the slide which covers tops and bottoms of the halves of the tape fits readily over each row of links and the loops at the rear of the links so that the slide is, in effect, guided by the row of loops of each half.
- This symmetry, above and below the plane of the fastener assembly, enhances the locking strength and facilitates handling of the slide.
- the slide fastener unit of the invention is simple and economical to manufacture on high speed looms and on ribbon looms, the slide fastener being produced during the weaving of the Y-tape with one shuttle by binding a synthetic filament into the short arms as a warp thread, e.g., alternately and at regular intervals.
- the weaving step to bind in the synthetic filament is efiected on a needle loom. After weaving, the woven-in synthetic filament is then deformed by heat and pressure into a row of links at the outward edge and a row of loops at the inward edge.
- the woven-in synthetic filament forming the rows of links and loops is provided with a plurality of uniformly spaced medial deformations or nips transverse to the longitudinal warp thread axis, all of the nips being located at the top, or crest surface, of the nodal portion of the U to simulate, in miniature, the crater of a volcano so that all of the craters in each half of the tape are in alignment longitudinally with each half of the supporting tape.
- the sections of the synthetic filament are thus situated between the short arms with each section being deformed by heating and pressing to form U-shaped links facing towards the edge of the tape.
- This U-shaped deformation of the synthetic filaments to form links is effected in accordance with the invention after weaving by heat deformation under compression.
- the slide fastener according to the invention may be produced on a conventional ribbon loom, it is especially advantageous that it be produced at low cost on a so-called high-speed loom, e.g., a needle loom with a very high pick capacity of well over 1000 picks per minute.
- the high picking rate on the needle loom is made possible with the method of the invention because the stiff synthetic filament which forms the row of links is introduced in the form of a warp thread in only one place and also because the double picking has no disturbing or interfering effect during the weaving on the needle loom.
- FIG. 1 shows, in cross section, an embodiment of a slide fastener according to the invention
- FIG. 2 shows the slide fastener of FIG. 1 in plan View
- FIGS. 3, 4 and are diagrammatic views which show halves of the slide fastener of FIG. 1 in intermediate stages of its manufacture.
- the slide fastener comprises two halves 1, 1a of a supporting tape which are constructed in the form of the Y-tapes.
- the short arms 2, 3 and 2a, 3a of the halves of the supporting tape are brought together by weaving the rows of links 4 and 4a continuously with loops 6 and 6a, respectively, these loops being shown in FIGS. 2 and 4.
- the free ends of the arms, top 2, bottom 3 and top 2a, bottom 3a partly hide the rows of links 4 and 4a, respectively.
- the rows of links 4 and 4a are each formed to provide loops 6 and 60, respectively, remote from the links, and are formed from a continuous synthetic thermoplastic filament, the loops 6 and 6a being set by heat as shown for the links in FIG. 5.
- links 4 and 4a comprise the individual fastener elements which are substantially U-shaped in the view shown in FIG. 1 and which are provided with the closing teeth 5 and 5a at the U-shaped arc situated at the edge of the halves 1, 1a of of threads 6, 6a at the left and right sides, respectively,
- FIGS. 3 and 4 the intermediate stage of manufacture after the completion of the heavy filament weaving operation is shown for a half of a slide fastener.
- the thermoplastic synthetic filament 8 is bound alternately into the two short tape arms 2, 3 at regular intervals in the form of a warp thread.
- Closing teeth 5, 5a are carried at intervals on this filament,
- teeth may be formed in the synthetic filament by preheating and pressing spaced portions thereof before it is woven into the tape arms, but this forming operation for the teeth also may be accomplished by heat-pressing or heat-stamping after the weaving operation has been completed. Broadly, the teeth are formed by heat deformation.
- FIG. 5 shows the state of manufacture of the half of the slide fastener during the heat deformation operation described above and following the weaving process described in connection with FIG. 1.
- the two arms 2, 3 of the Y-tape, together with the synthetic filament 8 which is still merely folded in the one plane, as shown during the manufacturing stage of FIGS. 3 and 4, are now compressed between pressure plates 10, 11 under the action of heat.
- This action bends the sections of the filament 8 between the arms 2 and 3 outwardly into a U-shape which extends or projects from the edges of the Y-tape arms and the heating followed by subsequent cooling sets this U-shape.
- the free ends of the tape arms 2 and 3 may be rigidly connected to the flat sections of the U-shaped fastener links by means of auxiliary adhesives, if desired, or by heat-sealing, if suitable heat-sealable threads, coated cotton or thermoplastic are used for the tape.
- the nips may be provided during the manufacturing process prior to or after weaving.
- the geometric relationship between the depth of the nip and the diameter or denier of the filament is important; no more than 35% of the diameter is taken out by the depth of the nip and the nip extends lateral across the link to a distance of -80% of the entire hemicircular arc.
- the filament is preferably a strong synthetic filament of the polyamide type or of the polyethylene terephthalate type.
- This last method (4) is preferred.
- a bar is located between the short arms 2, 3 which, in the vicinity of the instantaneous picking point or spot of weaving, is triangular in its cross section, analogous to the hollow triangular space show in FIG. 3. Further away from the picking point or place of weaving the cross section of this bar becomes almost a quadrilateral, as shown in FIG. 5.
- the nips are cold pressed with a punch brought up from the right.
- a slide fastener unit adapted for use with a fastener slide comprising two halves of supporting tape, each half of the tape consisting of a Y-tape, two rows of U- shaped links, one row being secured to each tape half by a woven heavy duty, continuous length synthetic thermoplastic filament warp thread, the upper and lower arms of each of the Y-tapes partly covering the row of links at each side to form parallel longitudinal bands exposing to view therebetween the middle of the U-shaped links where they come together, the filament warp thread being formed with a plurality of uniformly spaced medial nips, the links facing towards the edge of the tape, the leg of each U- shaped link having a single penetration through its respective tape arm and having loops inter-connecting respective links at the parts of the Y-tape arms remote from the edge and at the opposite side of said arms from the U-shaped portions to form a guide for the fastener slide, the medial nips being located at the top nodal portion of the U with all nips in each half
