Abstract: A controller for providing individual acceleration and velocity values to drivers controlling motors in a carton folding machine. In a first method, the controller provides the individual acceleration and velocity values by using unique addresses for each motor. The drivers receive the values and provide corresponding motor control signals to the motors they control. In a second method, the controller provides a master reference signal to the drivers along with acceleration and velocity values for the motors. The drivers generate electronic gear ratios for providing motor control signals to the motors they control based upon the master reference signal.

Abstract: An apparatus and method for folding a back flap of a carton. The apparatus stores parameters relating to a backfold process, and receives a value representing the length of the back flap to be folded. Based upon the parameters and the value representing the length of the back flap, the apparatus determines when to begin moving the hook for folding the back flap and when to stop moving the hook.
