Patented Mar. 5, 1946 i UNITED STATES PATE NT Tot-rice TAPE CONSTRUCTION James A. Hendley, Mlddletown. Conn., assignor toThe Russell Manufacturing Company, Middletcwn, Conn., a corporation of Connecticut Application February 1,1944, Serial No. 520,635 3 Claims. (01. 139 -407) This invention relates to improvements in tape constructions for the mounting of fasteners elements.

Heretofore. in the manufacture of woven tapes' designed for th mounting thereon of slidefasteners, each tape of what will ultimately be a pair of tapes on which the pairs of slidefastener elements are mounted, has been manufactured as an individual tape, and under this circumstance, the two pieces of tape that are to form a pair, each with slide-fasteners mounted thereon, may-.- and usually dooccur as pieces of .tape woven at widely-different times from-textile strands which, while they are intended to have the same qualities, including color appearance,. actually frequently differ in substantial degree.

' One object of this invention, therefore, is to provide tape-means which is designed andadapted to be separated along a longitudinal region into two tapes, after the pairs :of' fastenerelements are secured to the outside side-edges of the tape-means, the tape-means being woven as a unit, from textile strands of similar tensile strength and color and other characteristics, so that the final pairs of separate tapesiorpieces of ,tape which carry pairsof fastener-elements and are mounted upon agarment, hav substantially identical characteristics in all respects.

With the abov and other objects in view, as will appear to those skilled in the art from the present disclosure, this invention includes all features in the said disclosure which are novel over the prior art. r

In the description and claims, the variousparts and steps are identified by specific terms for convenlence, but they are-intended to be as generic in their application as the prior art'will permit.

In the accompanying drawing forming part of the present disclosure, in which certain ways of carrying out the invention are shown for illus Fig. 1 is an elevational or face view of-tapemeans constructed in accordance with the present invention, in whichthe tape-means consists'of two tapes or a pair of tapes temporarily connected.

' Referring to the form of the invention il1us trated in Figs. 1 to 9 inclusive, the tape-means or tape-constructionor tape-unit or twin-tape 20 includes two tapes or a pair of tapes 2| and 22 which are concurrently woven and held in sideby-side relation by temporary connecting-means in the form of a longitudinal zigzag strand 23 whichfextends through certain of theweft loops 24 ,of the weft strands or picks 25 (Fig. 4) of the right-hand tape 2| and through. certainof the weft loops 26 of the weft strands or picks 21 of thelefbhand tape 22. The right hand tape 2| is formed by warp strands 2a being' interwoven with the weft strands 25, and the left-hand tape 22 is formedby warp strands 29 bein nt rwoven with the weft strands 2l. It'w'ill be seen that in the weaving of the pair of tapes 2| and 22 and the strand 23, all concurrently, the weft strands in each tape 2| and 22 alternately loop back and forth at the opposite side-edges of the tape, to thus form a selvage -.edge along each of the opposite side-edges of each tape.

If the tape-means or twin-tape construction 20 is to be dyed or subjected to any finishing operation, this is done while the tapes 2| and 22 ter the zigzag strand has -means or double Fig. 11 is aview similar to Fig.1) of one of,

. any oil various ways.

of the tape-means 20 are still connected together, and where fastener-elements such, for example,

, as the slide-fastener elements 30 and 3| illustrated in Fig. 7 are to be employed,

cords

32 and 33 are first secured along and adjacent the opposite outside side-edges of the tape-means, as

illustrated in Figs. 5 and 6. One common way of securing such cords to tape is by sewing them on,

a illustrated in Figs. 5 and 6. Next, the slidefastener elements 30 and 3| are mounted upon the cord-containing regions of. the tape-means 20, as shown in Figs. '7 and 8. Next, a long length of tape-unit such as shown in Figs. 7 and 8 is 'cut into suitable short lengths for slide-fastener units, and either before or after mounting the operating-member thereon, and zipping the pairs of slide-elements? and 3| together, the con necting-strand 23 is removed. When the connecting-strand 23 has been removed, each of the tapes 2| and 22 will have the appearance illustrated in Fig. 9.

The connecting-strand 23 may be removed in It may be pulled out or cut out, or if made of cellulose acetate, for example, it may be removed by applying heat, or 5 or one of the artificial strands such as rayon, 3

cellulose acetate or nylon.

In the form of the invention illustrated in Figs. 10 to lzinclusive, the

tapes

34 and 35 of the tapemeans 36 are temporarily connected together by a plurality of weftor pick-portions 31 which 35 are formed by weaving a weft strand 38 (Fig. 12) with warps (not'shown) in the manner schematically illustrated in Fig. 12, to thusnot only form the temporary weft connecting-portions 31, but

and as having pairs of slide-fasteners secured on the cords, obviously any type of pairs of fasteners could be secured to the tape-means before forming two separate tapes from it, regardless of whether or not cords were to be suitable or desirable to employ in connection with such other type of fasteners.

Preferably, all operations such, for example, as the sewing-on of cords and mounting of fasteners along the opposite side-edges of the tapemeans, are performed prior to the separation of the tape-means into tapes. This not only provides a greater saving of time with consequent lower cost, than is the case where cords and fasteners are applied upon the individual separate tapes, but also permits of the originally manufactured tape-means which-is to be separated ultimately into two tapes, to be originally woven as a single unit so that the tensile strength, .thickness, appearance, color, aging characteristics, as to color shade, degree of stretch or shrinkage, etc., will be uniform in the two tapes which will ultimately form a pair of companion tapes in the final fastening-unit formed with the two tapes and which, in some instances, is mounted in a position upon a garment where differences in appearance of the two tapes is objectionable.

The invention may be carried out in other specific ways than those herein set forth without departing from the spirit and essential characteristics of the invention, and the present embodiments are, therefore, to be considered in all respects as illustrative and not restrictive, and all changes coming within the meaning and equivalency range of the'appended claims are intended to be embraced therein.

to also form each of the

tapes

34 and 35 with 4 salvage edges along its opposite side-edges. After cords and slide-fastener elements are mounted on the tapeeconstruction 36 in any suitable manner such,'for example, as illustrated in Fig. 7, the weft-strand temporary connectingportions 31 are cut so as to produce'two tapes similar to the tape 35 illustrated in Fig. 11.

, In making the form of the invention illustrated in Figs. 13, 14 and 15, the tape-means 39 is woven in any usual way of material such, for example,

as cellulose acetate and is provided with cords and slide-fastener elements along its opposite side-edges in a similarmanner to that heretofore fllustrated, and is then'passed longitudinally of itself into contact with a hot knife or hot roller,

or'the knife or roller can be passed along the tape-means 39, to melt the.portion of the woven cellulose acetate along the longitudinal region I. to separate the tape-means 39 along this region and form selvage edges Al and '42 respecno formed from the tape-means 39, the selvage's being formed as a result of the melting and stickingtogether of the; crossed warp and weft strands (not shown).

49 each consisting of a plurality of cord-strands,
