Originally manufactured for finetuning packaging, printing and converting industries, the POSI series of 1:1 phase transmissions includes models capable of handling up to 595 in./lbs. of torque at speeds of 100 rpm. In normal operation, the unit acts as a phase transmission with input and output shafts rotating in the same direction. Rotating the control shaft shifts angular position between the input and output shafts with up to 200 degrees advanced or retarded from null. The adjustment can be made while the machinery is shut down or running. Candy Manufacturing Co. Inc. (www.candycontrols.com) includes a key lock to prevent unauthorized adjustments.
