ABSTRACT:
A thermoplastic draw tape having thick and wide end portions with a relatively thin and narrow central portion between them is produced by movable clamps which stretch the tape between stationary clamps to produce the stretched, oriented portions of the tape. A plurality of movable clamps and a plurality of stationary clamps produce a plurality of stretched central portions so that the stretching time can be greater than the cycle time of bag making machinery with which the stretching apparatus is synchronized.
