Bindomatic AB, Stockholm, SE;
Abstract
In an apparatus for binding loose sheets in one or more folders there is utilized a regulating circuit means where an inserted folder (F) interrupts a light beam to a photodiode (16) which simultaneously starts a time counter (18) and closes the power supply (via 31) to the heating plate (2), wherewith the binding operation is carried out. The time interval of the timing counter is determined in response to the actual values of the width of the folders and the starting temperature of the heating plate. These values are obtained from a width detector (34, 7, 35) and a temperature detector (28), said values being fed into a microcomputer (19) controlling the timer. When the timer has counted down the time interval to zero, it interrupts the power supply to the heating plate (via 31).
