Draw-off device for narrow fabric looms

Abstract

The invention relates to a draw-off device comprising elastic belts (1, 2) for producing curved woven composites on narrow fabric looms. The draw-off device consists of two respective circulatory endless belts (1, 2), each of which is guided around a driving roller (3, 4) and a deflecting roller (5, 6, 7, 8, 9, 10). In addition to the driving rollers (3, 4), the edge regions of the belts (1, 2) also have extension drive mechanisms (11, 12, 13, 14) that only engage with the outer edges of said belts (1, 2). The belts (1, 2) preferably have a cross-denticulation which is located on the edges of the sides facing the driving rollers (3, 4), or which is continuous. The side of the belts facing away from the driving rollers is preferably structured. The radius of curvature of the woven composites can be adjusted by modifying the rotational speed differential between the extension drive mechanisms (11, 12, 13, 14) and the driving rollers (3, 4). It is not necessary to stop the loom in order to adjust the direction and radius of curvature.
