ABSTRACT:
A system for synchronizing the operation of two machines, a master and a slave, having a flow of material therebetween. A signal generator is associated with the master machine and depending upon an input from the master machine, generates a signal, normally a voltage that provides input to a variable speed control of the slave. Magnitude of the generated signal should be at least above that required to operate the slave at the maximum end of its normal operating range. Signal tuning means, preferably potentiometers are in line between the signal generator and the slave to tune the generated signal according to a predetermined plan. Certain of the signal tuning means are also connected to detectors located along the material path and receive feedback from the detectors to ascertain certain tuning of the signal. A method of synchronizing the operation of the master and slave machines is also disclosed and claimed herein.
