DEVICE OF DETECTING END APPROACH OF ROLL SHEET
Document Type and Number:
Japanese Patent JPH0632507
Kind Code:
A
Abstract:
PURPOSE: To satisfactorily detect end approach of a flexible rolled sheet made of a thin polyethylene film so as to have an extremely flexible sheet.
CONSTITUTION: A spool core guide 15 supports a rolled sheet 20 by means of spool cores 15 so that the rolled sheet 20 is rotatable and vertically movable, and a roll guide 16 makes contact with the outer peripheral surface of the rolled sheet on the spool core guide 15. Further, a sensor means 17 detects, at a predetermined position, the spool core 22 which descends along the spool core guide 15 under its dead weight due to a decrease in the diameter of the rolled sheet or consumption of the sheet body 21.
