Abstract:
An apparatus for binding a succession of stacked loads with a thermally fusible band, the binding apparatus comprising:(a) means for supplying a continuous length of thermally fusible band; (b) means for looping the band around a load so as to provide lapping parts of the band; (c) means for tightening the looped band against the load; (d) a band heater for heating the lapping parts of the tightened band and hence for uniting the same into a fused joint; (e) means for cutting the band that has been bound around the load, off from its continuous supply; and (f) heater control means for causing the band heater to be normally energized for a first preassigned period of time at constant intervals during the operation of the apparatus and for causing the band heater to be energized at least for a second preassigned period of time, which is longer than the first preassigned period time, in response to the heating of the band around each load, after the fusion jointing, in order to compensate for a temperature drop that might occur as a result of heating the band.
