Abstract

Thermoplastic sheets are monoaxially and/or biaxially stretched by rotating disks between a pair of feed rollers and a pair of draw-off rollers. The circumferential surfaces of the rotating disks are touched by the sheeting edges pressed onto them and maintained in firm engagement by atmospheric pressure. In the case of transverse stretching the rotating disks are arranged in a slanting position with regard to the direction of movement of the sheeting.
