Abstract
Tubes made from spirally wound paper tape are fed axially and suspended off the end of an arbor. When the tube reaches a predetermined length, the free end engages a free-hanging sensor plate, the movement of which interrupts a light beam to generate a signal which actuates a timer. The timer energizes a motor for a predetermined time to cycle a snap cutter through one circular orbit to sever the tube. The cutter is stopped at its original position by a brake.
