Title:
DEVICE FOR LOADING FIBER SHEET BAND IN SAME DIRECTION ON MOVED WIDE SUPPORT BAND
Document Type and Number:
Japanese Patent JPH02188357
Kind Code:
A
Abstract:

PURPOSE: To control the feed speed of a fiber sheet band supply device and make a load uniform and make a longitudinal edge straight, relating to the interval change for the wide support band of a not guided fiber sheet band part of the fiber sheet band part staying between the wide support band and the guide body provided in front thereof.

CONSTITUTION: A fiber sheet band 1 disposed its edge is supplied to an endless wide support band 2 circulated through a guide body 11. Therefore, a fiber sheet band part not to be guided 12 is formed between the contact place 14 to the wide support band 2 and the guide body 11 provided in front thereof. The interval change for the wide support band 2 of the fiber sheet band part 12 is monitored by a position detection device 15. When this interval change exceeds the upper/lower limit values of a target width change, the feed drive device of a supply device 3 is controlled and the tensile stress on the fiber sheet band part 12 is made unchangeable. Therefore, the fiber sheet band 1 is placed so that its edge is formed straightly for the wide support band 2.
