No. 38,324 Claims priority, application Germany .inne 2d, 1959 3b Claims. (Cl. 139--384) This invention relates to a method of producing slide fasteners having tapes with coupling elements formed thereon by projecting portions of continuous weft threads or filaments from which the tapes of the fastener are woven, said projecting portions being spaced at the appropriate intervals for coupling the tapes of the fastener together.

Slide fasteners of this kind have the advantage that the coupling elements form parts of the actual Weave of the tape or its fabric and can thus be produced wholiy o-r at least substantially in one operation with the looming of the tapes itself.

lt is the object of the present invention to provide a method whereby such slide fasteners can be particularly conveniently and readily produced, an object which is substantially achieved by looming the tapes with the aid of a multiple pirn picking motion and formingv the coupling elements from at least one group of weft threads or filaments, whereas at least one group of other weft threads or filaments traverses each tape without forming portions projecting from the loomed tape.

Preferably the group of weft threads or filaments which forms th/a coupling elements consist of monolar filaments of a plastically deformable material, such as nylon, whereas the weft threads or filaments which serve merely for the production of the weave of the tapes arethreads or filaments of thinner gauge which may or may not consist of the same material as the threads or filaments which form the coupling elements.

lf the slide fastener has a multi-pira weave its production can be facilitated if each tape as such is formed from picks which are simultaneously inserted into sheds formed by the warp at different levels. It has been found that this can be done even if the threads or filaments which serve for forming the coupling elements consist of a stronger material than the other threads or filaments used for weaving the tape and are also inserted in the form of picks either by running them off the pirn in a shuttle or by using grippers employing catch and draw threads or by usinga circular picking motion. The simultaneous insertion of the picks may either be by counter-picking from opposite sides or by parallel picking from the same side. Whichever method is used the time of production can be substantially reduced, usually by about one half.

ln the performance of the method according t'o the invention the groups of weft threads or filaments may consist of threads or filaments of uniform undeformed sections, and the threads or filaments' which form 'the coupling elements submitted to deformation at their looped ends which project from the tape edges after they have been inserted, and which are intended to provide the interengaging coupling elements. Such deformation may be imparted 'to them by pressure without or with the application of heat in such manner that the vertex of each loop is provided with the usual coupling projections or recesses.

Moreover, the threads or filaments which form the coupling elements can be roughened in orderV to improve their frictional non-slip engagement at cross-over places with the threads or filaments forming the principal part of the texture of the tape. The roughening can be producedy in various Ways. For instance it may be provided by attaching special projecting elements to the surface of the threads or filaments which form the coupling elements, by adhesive bonding, fusing, winding, braiding, or knitting them on in a manner known, for instance, in the production of so-called fancy yarns.

If the coupling elements are forme-d by monofilar plastic filaments the desired roughening may be formed by projections integral with the filaments and produced in a known manner by machining or plastically deforrning the filaments. ln some instances it may be sufficient, for example ifjit is desired to avoid further stiffening the filaments, to roughen only part of the circumference of the filaments which are to form the coupling elements. Partial roughening of the filaments circumference may be provided by forming an undular strip extending along the length of theV filaments or, alternatively, the filaments may if desired be easily roughened in such a way that said roughening will at the same time provide the projections required for the engagement of the coupling elements on the selvedges of the tv/o cooperating tapes of the slide fastener. j

When the two tapes forming the slide fastener are Woven in the manner proposed by the present invention, the weft threads or filaments which` are to form the coupling elements are conveniently inserted into one of the tapes to form right handloops and into the other tape to form left hand loops. Moreover, it is proposed to locate the pitchedportion of the threads or filaments which form the coupling elements in the region of the woven part of the tape, i.e. not in the exposed partof` the loops which project from the selvedge, but preferably on the inside edge of the bulbous selvedge. lf this is done the coupling elements willbe properly positioned for mutual engagement and the slide itself will be guided without undue wear. Moreover, in order to form the loops of the coupling elements the threads or filaments forming the coupling elements may be looped over a freely supported cantilever wire associated with the shed in a manner known in pile weaving looms, the loops being drawn od the wire as the looming of the tape proceeds.

Since, more particularly when using thicker monofilar threads or filaments for forming the coupling elements, these threads or filaments are considerably tensioned during the weaving process, the invention proposes to submit these filaments to a treatment at the end of the weaving process for the purposeof removing the tension therefrom and thus permittingthem to retain the shape imparted to them by the weaving process. The removal of tension can be economically combined with a process of dyeing the woven tapes.

According toanother feature of the invention the two tapes whichare provided with coupling v,elements in the form of right hand and left hand loops, respectively, are preferably simultaneously woven on a two-high loom the one abovethe other.

Inorder to avoid that thetape ends of the finished woven slide fastener are excessively stiffened by the presence of the threads or filaments which form the coupling elements,` it Vis proposed by the invention to discontinue the row offcoupling elements formed by filaments incorporated in the actual weave of the tape at regular intervalsandin these intervals to float said filament freely across the tape ends wich are not to be coupled together inthe completed fastener, These free filament ends can then be easily removed by snipping them ofi when the continuously woven tapes are cut into.

submits the threads or'filaments to some twist, one turn being thus inserted per loop, the invention further pro'- poses to provide the threads or filaments with an approaccesos 3 priate amount or countertwist before its incorporation in the weave of the tape.

Other advantageous features of the invention will explain themselves in the course of the further description of two preferred embodiments of the invention shown in the accompanying drawings, in which:

FiG. 1 is an elevational view of a slide fastener produced by the method according to the invention;

FIG. 2 is a cross section through the slide fastener taken along the line 1li-11 of F1G. 1;

FG. 3 is an isomeric simplified cross section, on an enlarged scale, through a row of coupling elements;

FiGS. 4 and 5 are fragmentary perspective views of a two-high loom for multiple shedding and a pair of simultaneously traversing shuttles, shown in simplified form in two consecutive positions;

FIG. 6 shows schematically the upper and lower shuttle picking motion;

FIGS. 7 and 8 are partial longitudinal and cross sections, on a larger scale in simpliiied form, of the portion of tape which carries the coupling elements of the slide fastener;

FIGS. 9 and 10 are a side view and a top plan view, likewise on an enlarged scale, of a weft thread or filament for forming a coupling element;

FGS. ll and l2 are two relatively perpendicular views, likewise on an enlarged scale, of a portion of the tape selvedge of a woven slide fastener and a die for forming coupling projections on woven coupling elements, and

FIG. 13 is a View corresponding to FIG. 8 after the die has been closed.

FIGS. 1 and 2 show a slide fastener which comprises two woven tapes 13 and 1liwhich, on the one hand, carry rows of coupling elements 15 and, on the other hand, serve for attaching the fastener to-an article of clothing either directly or indirectly with the interposition of an intermediate tape. As will -be understood by reference to the remaining figures, the coupling elements are formed by filaments 17 which are weft threads inserted into the weave only in the region of a bulbous selvedge 16 of a known kind wherein these threads form a at spiral shown in FIG. 3 wherein the broken oi ends of the dat spiral are respectively designated with 17a and 17b. The remainder of each woven tape, as will be seen by reference to FIGS. 3, 7 and 8 consists of Warp threads 1S, weft threads 19 and thick selvedge warp threads or runners 20. The weft threads 19 of the tape which do not participate in the formation of the coupling elements consist of cotton. The warp threads 1S are likewise a cotton yarn. However, in the region of the bulbous selvedge 16 warp threads 18' consisting of a nontearing nylon for binding the filaments 17 and so-called catch or draw threads 18 are incorporated which separate the cotton threads from edge 16 of the selvedge 16 which guides the slide 21 of the fastener, and they thus protect them from frictional wear when the slide 21 is moved for opening and closing the fastener, the movement of the slide being limited by end stops 22.

Both tapes 13 and 14 together with their rows of coupling elements 15 are simutaneously produced on a two-high ribbon loom with a double shedding motion and twin shuttles and pirns for parallel picking. FIG. 4 shows a two-high sley 23 with two shuttles 24 and 25, the one above the other, in a ribbon loom of this kind. The pirn 26 in the shuttle 24 carries a cotton yarn, whereas pirn 27 in the shuttle 2.5 carries the polyamide filament 17, for instance a nylon weft filament, for forming the coupling elements.

Each shuttle has a weft brake 2S and 29 for the pirns 26 and 27 and the filaments 17 and the weft threads 19 which run out of the shuttles. The Warp threads 18 are threaded through the mails of the heald shafts or harness for the simultaneous formation of two sheds indicated by arrows 311 and 30' for the simultaneous insertion therein of two weft picks in parellel. The warp threads in the region of the bulbous selvedge 16 are associated with special healds to permit the filaments 17 for forming the coupling elements to be inserted only in the region of the selvedge. For the formation of loops 17 of the filaments 17, which loops freely project from the selvedge a cantilever steel wire 31 is secured to the loom as shown at 32. in such a manner that the filament 17 will be looped over said wire. The woven tape 13 is drawn off -in the direction of arrow 33, the coupling loops 17 being simultaneously withdrawn from the wire 31. At the front side of the loom there is provided a special stationary guide 34 which prevents the woven tape from being laterally pulled out of shape or distorted and which also ensures a clean feel.

The upper shedding motion of the two-high ribbon loom is schematically shown in FIG. 6 at the top and the lower shedding motion at the bottom. F-GS. 7 and 8 show the interlacing of the cotton warp threads 1S with the nylon warp threads 1S' in the weave. The warp threads 18 interlace with only one side of the laments 17 which form the coupling elements, whereas the nylon warp threads 1S are taken over both sides of the {ilaments 17. The catch or draw threads 18 draw the cotton threads, in the region where the slide travels lalong the edge of the tape, into the interior of the bulbous selvedge Y16. The position of the weft threads 19 which do not participate in the formation of the coupling elements, although these are conveniently inserted into the shed at the same time as the filaments 17 which form the coupling loops, is indicated by dotted lines 19 in FIG. 8. For the sake of clarity the thick selvedge threads 20 and catch threads l18" which are included in the bulbous selvedge are not specially shown in FiG. 7.

The monolar nylon weft filament 17 which is about 0.4 mm. thick or more has au overall roughened surface in order to improve the cohesion of the Weave. As will be seen particularly by reference to FIGS. 9 and 10 the ronghening of its surface is produced by plastic deformation of the filament cross section. By the impression of a succession of recesses 11 into one side of lament 17 in the direction of the warp threads 18 projections 11 are formed in which the warp threads 18, 13 engage, thus securing the weft iament 17 which forms the coupling elements. At the same time their presence imparts a greater degree of exibility to the filament. Moreover, the plastic impression of the recesses 11 widens the {ilament 17 in the direction of the recesses, as shown at 12, and these sections can be utilized to form the coupling teeth of the coupling elements which need not therefore be specially shaped. Furthermore, these widened sections in the region of the inner edge 16 of the bulbous selvedge of the tape improve the manner in which the slide is guided and reduces irictional wear.

lf the filament for forming the coupling elements, as shown in FIGS. 11 to 13, is an undeformed nylon filament, then the coupling loops 17 may be shaped after the looming process in a die comprising two movable jaws 36 and 37 with dies 38 for the reception of the coupling loops 17 and channels 39 for guiding a ram 49 which forms coupling teeth 35 on to the end of the loops. FIG. 13 shows a die when the jaws 36 and 37 have been closed and the ram 40 is in operative position.

After the coupling teeth 3S have been shaped, the tapes 13 and 14 are submitted to a heat treatment which removes any remaining tension from the nylon filament 17 which has a diameter of 0.4 mm. or more. The shape imparted during the weaving process to the filament which forms the coupling element will therefore now be retained, even if the constraining warp threads 18 and 18' were actually removed. If the slide fastener tapes 13 and 14 are to be dyed after having been woven, the treatment for consolidating their shape may be combined with the dyeing process in a bath, so that a separate treatment for consolidating the filaments will not be required.

As has already been mentioned the illustrated embodiments are merely illustrative of the invention and are not intended to limit the scope of the invention in any respect.' Various modified modes of performing the invention can be devised. For instance, the filaments which form the coupling elements may be roughenedv by a process of machining the same; 'Y Moreover, instead of only part of the surface of the filaments being rou'ghened,` the roughening may be extended over -major regions or all of the filament surface. Furthermore, instead of forming projections and the like which are integral with the filament, these may be providedV by adhesively bonding, welding, winding, or knitting suitable projections 011-' to the Vfilament in the manner-that is conventional in the various methods of producing so-called fancy yarns. Instead of a solid filament va piping could also be used. The coupling elements themselves might alternatively be provided on the face instead of on`the edges of the cooperating tapes, the laterally projecting tape edges being used, on the one hand, for afiixing the same to an article of clothing orthe like`and, `onk the other hand, for covering the coupling of theslide fastener; Furthei`v more, the tape might-beof Y-section, as is` likewise'al. ready known to the art, one flange being used f or fastening the tapeand the other flange as a 'covering for rendering thecouplingelements on .the-third flange invisible. Moreover, insteadV of being formed by the weft threads, the couplingelements' might "be" formed- -by the warp threads of the tape.

Instead of passing through the tape in the form of a spiral, the filament forming the coupling elements might be worked into one or both sides of the tape, for instance by interlacing the same in a kind of meander. It may also be sufiicient if the filament which forms the coupling loops is worked into the tape when the latter is being loomed in such a way that the loops are interlaced by only a single pair of crossing threads. The width of the tape behind the chain of coupling elements may be limited to adapt it to any desired method of attachment by sewing, cementing, welding, or some other method of fixing the same. The spacing of the projec tions and recesses formed by the roughening process may be so close that special attention to their particular position when utilizing them as coupling teeth is not required, because the large number of projections will then ensure that satisfactory cooperation and engagement between the halves of the fastener will actually always occur. The fioating arrangement of the loop forming filament between the ends of the fastener which are not to be coupled can be readily achieved by suitably controlling the shedding action of the loom, i.e, by setting the shed during the looming of the row of coupling elements to centre-lower instead of to upper-center lower when the free ends of the tapes are being woven.

Instead of picking with shuttles the method could be performed on a shuttleless loom equipped with giverand taker-grippers. In such a case it is advisable to provide special catch or tension threads at the selvedges of the tape. Also the polyamide pick might be inserted by a rotor, that is to say by acircular picking motion. Instead of parallel picking, a counter-picking motion might be employed. Moreover, since the insertion of a monofilar pick for forming the coupling elements by means of a shuttle and pirn and helical interlacing, subjects the filament to twist, one turn being imparted to the same during the formation of each loop, it is advisable to provide the filament with a twist in the opposite direction before incorporating the same in the weave.
