Abstract

PURPOSE: To control the racing time of a new reel so as to be optimum, by disusing a preliminary diameter setting device for a web letting-off gear, and detecting the loading timing through a microcomputer.
CONSTITUTION: When a reset signal 14 of a roll diameter detector 25 is released, the operation of a microcomputer 30 is started. A counter 32 counts the mumber of pulses from a pulse generator 12 through a mono-stable multivibrator 33 and an AND gate 34 and reads it as the roll diameter value of an old reel 1. A counter 31 reads the roll diameter values of the old reel 1 when it is reset and after it has been rotated a given number of revolutions in order to calculate the thickness. The microcomputer 30 outputs a preliminary diameter signal 16 based on these measured values. A preparation completion signal 15 opens an AND gate 35, which outputs a new-reel 2 paste position 5 signal 17. When the roll diameter value of the reel 2 becomes less than the value set by a final diameter setting device 20, a final diameter signal 18 is outputted, and the web on the reel 2 is loaded on the reel 1. Thereby, the racing time of the reel 2 is controlled so as to be optimum.
