APPARATUS FOR WEAVING MULTIPLY TUBULAR FABRICS 



This invention relates to a process of producing multiply tubu- 

 lar fabrics such as gas tubing or fire engine hose, without the 

 necessity of drawing one tube within another. The loom weaves 

 one ply of fabric directly upon another in such a manner that the 

 intersections of the inner ply are tilled by the threads of the 

 outer ply, producing a locked effect which increases the non- 

 leakable properties. 



The apparatus consists of a multiplex circular loom with a 

 central weaving pin having a number of weaving surfaces along 

 its length, superimposed shuttleways with supports, a set of shut- 

 tles arranged to travel in each raceway, a set of heddles for 

 each shuttle, warp and weft thread-tensioning devices, means for 

 operating both, and an arrangement for drawing the woven fabric 

 from the weaving pin and from one weaving surface to another. 

 The operating mechanism for each set of devices weaves a cir- 

 cular ply of fabric in one direction while the other set weaves a 

 circular ply in the opposite direction, but directly upon the ply 

 woven by the first device. In other words, the shuttles at one 

 elevation operate in a direction opposite to that of the shuttles 

 of another elevation. The heddles work in unison with the par- 

 ticular shuttle for which they make the shed. 



As the bobbin unwinds, the tension is maintained in propor- 

 tional relation to the diameter of the bobbin and the peripheral 

 winding speed. The weft thread in unwinding travels from one 

 end of the bobbin to the other, thus centralizing it and equalizing 

 the lengthening and shortening of the thread from different 

 points of the bobbin to the spindle. The thread passes over the 

 spindle to the conical groovetl tension wheels, where it passes 

 back and forth until the right tension is attained. The warp 

 threads coming from their respective spools are tensioned by 

 passing through guide bushings over and under removable rods 

 having a surface of leather or other friction material. 



The finished multiply fabric is pulled from the weaving pin, 

 after the last ply has been woven, by the take-off mechanism 

 which consists of two adjustable pressure rollers furnished with 

 gripping-pin bars. The pins are of sufficient length to penetrate 

 the outer ply of fabric and to engage the inner ply, maintaining 

 an even tension on both plies as the fabric is pulled from the 

 weaving pin. The tendency to tear the fabric or the crowding 

 of the fabric between the pins is fully overcome. The weaving 

 pin has two weaving surfaces with the connection portion re- 

 duced in diameter. The reduced portion serves to guide the 

 fabric from the lower weaving surface to the upper. — Maglois P.
