PAPER DAMAGE OCCURRENCE PREVENTIVE METHOD AND DEVICE FOR PAPER TRANSFER TIME ON POPE REEL

摘要

PURPOSE: To prevent damage of paper at paper transfer time by cutting the paper almost at a right angle on this side of a spare core when winding becomes a proper size, moving the formed winding start edge under the spare core, fixing the winding start edge by bringing the spare core into contact with the paper, and starting the winding by surface driving of a rotary drum. ;CONSTITUTION: When present winding (a) becomes a proper size, a detecting means is operated, and a paper transfer starting command is outputted. Thereby, an operation cylinder 30 raises up a swinging arm 26, and brings a belt 29 into contact with a spare core 6, and rotates it together with a rotary drum 7. Next, a rotary cutter 9 is rotated, and a paper 1 is cut. This cutting angle is not a complete right angle, but is set at an angle close to this, and cutting resistance is reduced. The winding start edge of the paper 1 after this is cut is sent under the spare core 6 by feed rollers 2 and 3. Then, a receiving body 21 is lowered by a raising and lowering cylinder 22, and the spare core 6 is dropped on the paper 1, and the winding start edge is fixed flatly by an instantly fixing means.;COPYRIGHT: (C)1994,JPO
