Improvements in and relating to circular weaving looms
659,417. Circular looms. SAINT FRERES SOC. ANON. Jan. 25, 1949; No. 1999. Convention date, Jan. 28, 1948. [Class 142(ii)] Each shuttle is followed by a rubber-clad roller 1 driven at a peripheral speed which is slightly higher than its orbital speed, so that it lifts the warp threads 12 and deposits them behind their previous position to counteract the tendency of the shuttles to drag the threads round the loom. When the shuttles are driven by rollers 3, the roller 1 is on the same shaft as the roller 3 and is of slightly greater diameter. The weft laying arms on the shuttles carry barbs which pluck the warp threads to equalize their spacing before they are lifted by the roller 1.
