ABSTRACT:
Process for making zigzag folds in loops of a continuous feed of flexible sheeting, especially textile sheeting, so that the sheeting (9) is drawn in with a layering device (13) which moves back and forth at a right angle to the feed direction and the sheeting is folded at the outlet. The sheeting (9) is drawn in between the two corotating rolls (4) which constitute the layering apparatus (13) so that the sheeting lies against one of the rolls (4), and the rolls (4) change their direction of rotation at the two opposite points in their back and forth movement in such a way that the rolls (4) rotate toward the left when they move laterally to the right, but the rolls rotate toward the right when they move laterally toward the left, and the sheeting (9) is delivered for folding by the roll (4) which is in the rear in the direction of lateral movement.
