Abstract
An apparatus to be appended to a rotary printing press for binding successive stacks of printings with a thermally fusible paper band. Included is a band looper for loosely looping the band around a load on a platform. After having been tightened against the load, the band has its lapping parts heated by a band heater into a fused joint and is cut off from its continuous supply. A heater control circuit is provided for causing the band heater to be normally energized for a preassigned period of time at regular intervals during the operation of the apparatus, keeping the heater heated to a temperature necessary for melting the thermoplastic overlay of the paper band. After the heater has heated the band on each load, the heater control circuit causes the heater to be energized for a longer period of time which is enough to compensate for a temperature drop due to the heating of the band.
