Patented Mar. 21 19133 UNITED STATES PA ENT oFF 'ca EDWILT M. GOLDSMITH, OF PHILADELJPHIA, PENNSYLVANIA, 'ASSI GNbR TO A. CORPORATION OF PENNSYLVANIA BUTTON-HOLE TAPE npplication filed September 27, 1930. Serial No, 484,858.

Theobject of my invention is to produce a woven tape or ribbon of indefinite length containing button-holes whichare formed solely by the interweaving of the warp and weft ag d which are also finished, solely by the Weaving process, to simulate button-holes Which'are formed by cutting and sewing.

A preferred embodiment of the invention is shown in the drawing, is Whichi Fig. l is a plan View of the tape as it appears .to the eye. V

Fig. 2 is an enlarged detail view illustrating the novel means of interlacing the threads to form the tape.

Inthe weaving of the fabric there is utilized a set of warp threads which extend longitudinally of the fabric and a plurality of (preferably two) weft or filler threads a and b which .extend transversely of the fabric. 7

In the formation of the main body of the tape the two weft threads at and Z) both extend entirely across all the warp threads, interweaving therewith in any ordinary way, as by a one-and-one weave. In the embodiment shown, one weft thread a is thrown across'the shed in one direction. Then the warp threads are reversed and the other weft thread b is thrown across the warp shed in the same direction. Then the warp threads are again reversed and the weft thread a is thrown across the warp shed in the opposite direction. Then the warp threads are again reversed and the weft thread I) is thrown across the warp shed in the latter direction. Thereby a repeat is formed.

This operation continues until just within a few shots of weft (preferably four shots) prior to starting the formation of one end of the button-hole. For convenience, the warp threads, in the following description, are designated 0, cl and e and e, e and e representing the middle warp threads which are intended to extend along opposite sides of the button-hole and'o and d representing the warp threads between the middle warp threads and opposite longitudinal edges of the fabric and which are or may be always interwoven with weft threads insubstantial- I the tape.

ly the same way throughout the length of the tape.

The shots of weft which immediately precede the formation of the button-hole do not interweave with the middle warpthreads e i and 6, but float over them. Thus, in s'uccessive warp threads, weft thread I) floats overand then under warp threads 6 and e and weft thread a floats over and then under warp threads 6 and 6'. This operatiton Beyond the above described floats, weft thread a inter-weaves with warp threads c and e and weft thread I) interweaves with.

warp threads cl and 6, thereby forming two separate longitudinally extending fabrics on opposite sides ofthe longitudinal center of By imposing suitable tension upon the weft threads in a direction away front the longitudinal cen'te'rtoward optending central opening constituting thebutton-hole.

The manipulation of the threadsat the otherfend of the button-hole to 'floa'tthe weft threads over the central warp" threads 6" and e and then interweave' both weft threads with all the warp threads. to form a new length of" body fabric wi ll'be understood from the foregoing description.-

A section of, tape containing one buttonhole, as it appears to theeye, is illustrated in Fig. 1, wherein w is the body ofthe fabric, g/ the floating threads at the ends of the button hole, a the-closely associatedwarp threads along-opposite sides of the buttonhole, and a: the button-hole.

- The number of warp threads which are closely associated along the longitudinal margins of the button-holes, the number of shots ofweftwh'ich are floated,and the mini ber ofwarp threads over'which the weft threads float, are, of course, sus'ceptible to variation. Nor is it necessary tolimitithe number of weft threads to two or to adhere to any other specific feature abovedescribed (except so far as any such features may-be specified in the claims) the embodiment shown being one which is preferred because of its simplicity.

- Having now fully described my invention,

what. I claim and desire to protect by Let ters Patent is: T

1. A woven button-hole tape. having elongated button-holes extending in the direction of the warp-threads comprising two sets of warp threads extending respectively along opposite sides of the tape, and two edge of. the tape in each pick involved in the formation of a button-hole, whereby the tape is of close weave both beyond and at the sides of the, button-holes, the weft threadsof each side being extended over a limited number of warp threads of the other side at both ends of each button-hole.

2. A woven button-hole tape having elongated button-holesextending in the direction of the warp threads comprising two sets of warp threads extending respectively along opposite sides of the tape, and two weft threads, both weft threads being interwoven with both sets of warp threads to form the body of the fabric between buttonholes, and one weft threadbeing interwoven with only one set of warp threads and the other weft thread being interwoven with only the other set of warp threads to form a button-hole, each weft thread extending from an edge of a button-hole to the corresponding edge of the tape in each pick in- 7 the sides of the button-holes, the weft threads being floated over a limited'number of central warp threads of both sets at the ends of each button-hole, the floats being the axis of a button-hole. 3
