Abstract

A cutting machine includes an endless conveyor and a loading ramp having movable loading arms which continuously shift the cut material in an upward direction of the loading ramp to conveyor. The rear deflector wheel of the conveyor is driven by a squirrel-cage motor, and the drive of the loading arms is, via the conveyor derived from the front deflector wheel. A slipper clutch is interpositioned within the drive between the motor and the loading arms, and the slide torque of the slipper clutch as reduced to the motor shaft, exceeds the breakdown torque of the squirrel-cage motor.
