Abstract

PURPOSE:To prevent the cut end edge of a web from being deformed into a curved shape, by rotating a material web roll while the material web roll is bounced up by means of beads incorporated to web releasing rolls. CONSTITUTION:When a web stretching machine is operated, a material web roll 100 set on a pair of web releasing rolls 1, 1 is rotated while it is bounced up by a plurality of beads 7 formed on the pair of web releasing rolls 1, 1 so as to release the web material 101 and then to fed it to a pay-out roll 2. Accordingly, the material web roll 100 is floated up in its entirety in an oscillating condition, and therefore, strain conditions of the material web 101 which is continuously released from the material web roll 100 are successively eliminated at instances of the floating-up. Further, in a slackened part 102 of the material web 101 just before the pay-out roll 2, a strain condition which has bean left in the material web without being eliminated, is eliminated.
