ABSTRACT:
A wrapping machine has film feed rolls driven through a one revolution clutch to advance a wrapper length of stock in each cycle, past a continuously driven cutter, to separately driven and intermittently operating sheet locating belts. First sensing means disengage the clutch when no articles are ready to be wrapped. Second sensing means stop the belts in correct wrapping position of the sheet. Movable pressure rollers hold sheets on the belts, to stop with belts. Electrically actuated lifting devices lift the rollers from the belts. Cyclically driven switch means and holding circuits are connected to successively engage an electric clutch to drive the belts while opening a circuit to a brake for stopping the belts and deenergizing the roller lifting devices, then deenergize and disengage the electric clutch while conditioning the circuit to the brake for completion by the second sensing device, then energize the lifting devices for lifting the rollers from the belts. Other cyclically actuated switches and holding circuits condition the first sensing means to disengage the one revolution clutch and retract a movable striker blade from coacting cutting relation with the cutter when the first sensing device is activated during a short interval near the end of the rotational cycle of the one revolution clutch.
