Specification of Letters Patent.

Patented July is Application filed December 13, 1921; Serial No. 522,6?4l.

To all whom it may concern:

ing bicycle and auto canvas, a textile fabric having relativelyfew weft threads. Heretofore it has been customary in Weaving such materials to Wind the warp threads upon warp beams and then introduce them into the loom. The substitution of a full warp beam fol-an empty one necessitatedv stop ing of the loom, resulting in loss of pro uct-ion. Moreover, the-preparation of the warpbeam required the help of a skilled workman, the weaving master, thereby adding to the cost of production. Furthermore,

it often happened that the first tissue was unserviceable and the last portion of the warp, the so-called drum, was lost. Besides, the last portion of the warp threads was lost during warping and beaming up;

The above mentioned drawbacks are avoided by the present invention according to which the warp threads, Without being beamed up, are fed from one or more creels of novelconstruction to a novel form of tension device. The advantages of the invention are many. By reason of the omission of preparatory machines and the weaving beams, fewer workmen are required and there are practically no losses of material and the working-is continuous owing to the r 2 to a feeding or brake device, consisting.

fact that the empty bobbins of the warp threads ,niay be graduallyreplaced by full bobbins during weaving.

The drawings illustrate one embodiment of the invention by way of example.

Fig. 1 shows schematically a sideelevation of thedevice with the loom.

Fig. 2 is a plan view of this device, with out the loom.

Fig. 3 shows on a larger scalea front elevation of a thread frame with some bobbins and thread guides mounted on the same.

According to the invention the Warp threads of the bobbins, placed upon the thread frames 1, are fed through the reed of a roller 3, having a covering of a fricti0n-material, e. g. felt, with front and back tension rollers 4 and 5., This device is conat both sides the planes of V-shap secured to the vertical frames 1, so that the structed in such a manner, that the wai'rp threads are subjected to suiiicient friction, While however it is still possible. to draw through each thread individually without danger of rupture, which is important in repairing threads and removing eventual mistakes in the threads. From here they pass over the smoothing beam. 6 to the loom, indicated as a whole by '2 in Fig. 1. The reed 2 is mounted more or less resilientl e. g. on a brace 8. The felt covered roller 3 acts as a feeding or brake device, so that an equal feeding of the warp threads is ob tained.

The resilient suspension ofthe reed con tributes to the warp discharge and decreases the danger-of rupture.

As appears fromFi 2 the frames may be verylong so that t e height may be so small, that all bobbins are within the reach ofa boy or girl whereas nevertheless a very largeiumber of bobbins may be mounted on the frames. V

For obtaining an easy substitution of emptybobbins by full ones the bobbin pins are placed perpendicular to ed carriers 10, which are bobbins 12 are-disposed under an angle of about 455 with respect to the vertical plane.

From the bobbins the warp threads run through eyes in. the thread guides 13 in such a manner, that each thread is guided in its own eve.

{By this device it results that in the case of a rupture of a thread, the broken thread. can be found directly and repaired by the assistant without interruption of the worlr.

l. l/Veaving apparatus, comprising a ten" sion device and a plurality of spaced creole arranged in front ofsaid tension device, said tension device comprising a pinrality of cooperating rollers and a reed yieldingly supported in front of said rollers, and each of said creels comprising a carrier extend ing radially with respect to said tension de vice, and a row of bobbin pins supported by said carrier.

2. Weaving apparatus, comprising a tension device, and a plurality of spaced creels arranged in front-of said tension device, said tension device comprising a plurality of cooperating rollers and a reed yieldingly supported in front of said rollers and each of mg a covering of friction material, tension rollers having a relatively small diameter in comparison to the diameter of the friction roller, said tension rollers being arranged at the front and back of said friction roller and in close proximity thereto, a reed in front of said friction roller, and yielding means supporting said reed from said frame. In testimony whereof I allix my signature.
