WOVEN WEB AND PRODUCTION OF THE SAME.
To all whom it may concern:
Be it known that I, FRANK H. STEWART, a citizen of the United States, residing in Elkins Park, Montgomery county, Pennsylvania, have invented certain Improvements in Woven Webs and Production of the Same,
of which the following is a specification.
My invention relates to that type of narrow ware fabrics such as tape, belting, ribbon, or the like (hereinafter, for convenience, and to avoid repetition being characterized simply as web) in which the weft thread is carried to and fro through one and the same shed of Warp threads and, at one selvage of the web forms loops extending beyond the Warp thread at that edge, the objects of my invention being to prevent the drawing of these loops into the shed of warp threads on the return run of the weft thread, and also to prevent raveling of the edge warp thread, the latter not being confined by the loops.
In the accompanying drawing,
Figure 1 is a face view, on an exaggerated scale, of a piece of web wovenin accordance with my invention;
Fig. 2 is a sectional view on theline 22, Fi 1' Fig. 3 is a view similar to Fig. 2 but illustrating web embodying a modified form of my invention, and
Fig. 4 is a view of certain mechanism used in weaving web such as shown in Figs. 1 to 3.
Referring to'the web shown in Figs. 1 and 2 of the drawing, 11 represent a set of warp threads and 3 a weft thread interwoven therewith, the warp threads 1 being shedded between successive to and fro runs 3 and 3 of the weft thread 3, so that double runs of the same lie in each shed of the warp threads and form loops 4 at one selvage of the web.
l/Vith the loops 4 are intertwisted a pair of selvage threads 5 and 5, these selvage threads being given a half twist in respect to each other between each of the successive runs 3 and 3 of the weft thread so that the selvage threads embrace each loop 4 and are twisted in respect to each other between suc cessive 100 s. The selvage threads, thus intertwiste serve to grip the loops 4 and prevent them being drawn into the sheds of the warp threads 1 andalso retain the edge warp thread in place and prevent it being.
raveled out Specification of Letters Patent.
In the form of web shown in Fig. 3 of the drawing, the selvage threads 5 and 5 are given a full twist in respect to each other be tween successive loops, thus causing them to V interlock with each other and exert a tighter grip upon the loops than is the case with web as shown in Figs. 1 and 2.
The selvage threads may be disposed at the left hand selvage of the web, at the right hand selvage of the same, or in case two weft threads are employed, at both selvages.
Although the selvage threads may be supplied and twisted by any suitable means, I prefer to make use of mechanism such as shown in Fig. 4 of the drawing. The threads 5 and 5 are fed to the web parallel with the edge warp thread and are supplied from spools 6 and 6 mounted upon a disk 7 secured to a shaft 8, and are guided by eyes 9 and 9 formed in the disk 7 Between each of the successive runs 3 and 3 of the weft thread 3, a movement of either half or full rotation is imparted to the shaft 8, thereby V Patented Dec. 9, 1919. Application filed April 14. 1919.. Serial No. 289.841.
correspondingly rotating the thread carrying and guiding disk 7 and twisting the threads 5 and 5 in respect to each other and causing them to embrace and grip the last formed loop 4.
I claim: 7
1. A woven web comprising a set of warp threads, a pair of selvage threads disposed at one side of the warp threads, and a weft thread passing to and fro through each shed of Warp threads and forming loops at the edge of the web, said. pair of selvage threads embracing each loop and being twisted in respect to each other between successive loops. 7
2. A woven web comprising a set, of warp threads, a pair of selvage threads disposed at one side of the warp threads, and aweft thread passing to and fro through each shed of warp threads and forming loops at the edge of the web, said selvage threads being disposed one above and the other below said loops throughout the web and being interlocked with each other between successive loops.
3. The mode herein described of weaving a web, said mode consisting in passing a weft thread to and fro through each of a number of successive sheds of warp threads,
and between a air of selvage threads thereby forming oops 1n sald weft threa at the edge of the web and between the selthereby forming loops in seid Weft thread at the edge of the web and between the sel- 10 vage threads, and interlocking said selvage threads with each other between successive loops.
In testimony whereof I have signed my ilaine 'tothis specification. r
. FRANK H. STEWART.
