Abstract
PURPOSE:To reduce driving force by a method wherein the widening of the holding pitch of an endless linkage at stretching section is controlled by a screw, the groove pitch of which widens gradually. CONSTITUTION:When an endless linkage 2 is driven, bearing rollers 17 are run in a stretching section by being guided by guide rails 4 and 6. In addition, in the longitudinal direction, the holding pitch of the sheet-like material 1 of the endless linkage 2 is gradually widened by means of the groove pitch of a screw 19. On the other hand, in the lateral direction, the running locus is controlled by the guide rails 4 and 6. Accordingly, the running resistance of the endless linkage 2 can be reduced, resulting in allowing to drive the linkage by lower power.
