THE TRAUTVETTER BIAS FABRIC AND LOOM. 



IN the early days of hose pipe bicycle tires, many fabric weaves 

 * were designed, with the object of producing a perfect tire. 

 .•\mong the many examples of weaves introduced was the Good- 

 year rivet fabric, well known at that time. 



A modified form of tliis fal)ric, especially desi<jned for motor 

 tire building, has been recently perfected and a special loom con- 

 structed for its manufacture. Both fabric and loom arc protected

Tr-mtvetter Bias Tire' Fabbr. 



warp tiireads are arranged lengthwise, parallelto each other, anu 

 the sets of reinforcing threads e.\tend diagonally across the 

 fabric in opposite directions from one selvage to the other and 

 return, so that the bias threads cross each other between the 

 adjacent picks and also at the top of the warp threads, which 

 pass over the tiller threaJs, while the bias threads pass under 

 them. The bias threads cross each other under the filler so tha' 

 the warp threads, the bias reinforcin.i threads and the filler 

 threads are compactly interwoven, forming a strong and durable 

 fabric, capable of withstanding strains in any direction. The 

 small openings formed in the weave are filled with rubber and 

 the adjacent threads completely embedded by the calendering 

 operation, thus forming thousands of small rubber rivets that 

 serve to prevent separation of the fabric plies when built up in 

 a tire and vulcanized 



BIAS FABRIC LOOM. 



The loom which makes this fabric embodies several novel 



features in construction that are of interest. For instance, the 



reel and harness are quite diflferent from those of the ordinary 



loom. The warp threads unwind from a warp beam journaled 

 in Ibc Ici.ser rear [■■rlion of the frame, and the bias tlircads 

 IT .'.In I fro II spi ols journaled in a rcvolvable reel that is mounted 

 on lb' l.ip of the frame, while the filler threads are st:p|.licd by 

 a .shuttle niechanisin and are beaten up against the fabric by 

 an ordinary lay.
