Abstract
A textile piece 10 to be coated with rigidizing plastic supplied by a compressing cylinder 12 is fed through a nip zone between the cylinder and a driven roller 16 by conveyors 15, 17. The compressing cylinder is mounted between pivotable levers 18, 19 counterweighted in one direction, and urged in the opposite direction to squeeze the fabric by a lateral array of pneumatic cylinders 21. The cylinders are individually controlled by a lateral array 13 of photocells which continuously sense the width of the incoming textile piece, whereby the nip zone force is automatically controlled as a function of fabric width to provide a uniform coating pressure on irregularly shaped or oriented textile pieces.
