Abstract: A loom including a drive device for weaving fabric from warp yarn extending from a source over a back rest provided adjacent one end of the loom and after being woven into fabric being fed over a breast beam positioned adjacent the other end of the loom. A driven roll over which the warp is guided without slippage is disposed in front of the back rest and at least one driven delivery roller over which the woven goods is guided without slippage is disposed after the breast beam. The guide roller and the delivery roller are driven in synchronism and there is a driving connection therebetween, as well as with the main drive shaft of the loom.

Abstract: A device for equalizing the warp yarn tension in a loom having a movable back rest and a fixed beam spaced therefrom. The back rest is moved to and fro the beam during the weaving operations with the warp yarns extending thereover. A pressure cushion is carried between the back rest and the beam parallel to the back rest and the beam. The pressure cushion is compressed and relaxed as the back rest moves to and fro said beam during the weaving operation for equalizing the warp yarn tension.
