METHOD AND APPARATUS FOR MAKING PILE FABRICS ABSTRACT OF THE DISCLOSURE A web is placed on a grooved cylinder, folded by pressing it into the cylinder grooves, and attached to a backing sheet to form a pile fabric. Folding is performed by rollers with blades which enter and move along the length of the grooves. The rollers are guided precisely by guide members on their opposite axial sides. To prevent the rollers from pushing the textile material across the grooved cylinder surface, the rollers are rotated independently of their contact with the web.
