ABSTRACT:
In a thermo-cementing and folding machine, a gear pump operates to supply adhesive at a rate which is dependent upon the speed of rotation of a main drive shaft, by which workpiece feeding means of the machine is driven. The machine has also a facility for varying the rate of feed of a workpiece by the workpiece feeding means without varying the speed of rotation of the main drive shaft. The ratio of the rotational speed of the shaft to the operating rate of the pump is varied in response to variation of the workpiece feed rate. This arrangement is achieved by computer control, the gear pump being driven by a stepping motor for this purpose. In addition, at the end of each work cycle, use of a stepping motor facilitates "suck back" of adhesive, and a "fast forward" adhesive upon initiation of the next work cycle.
