Abstract
Abstract An apparatus for slicing ropes of extruded material into predetermined lengths as the ropes are forced through extrusion orifices in an extrusion apparatus. A motor and clutch are provided for activating the slicing apparatus. A brake, a rotatable cam, and a cam sensing device are provided for stopping the slicing apparatus at a predetermined location, so that none of the orifices are blocked by the slicing apparatus.

Claim 1
Independent Claim
222 words
A cutting apparatus comprising an arm member and a knIfe attached to said arm member, means for mounting said arm for rotational movement about an axis, means for causing said arm to rotate about said axis including a motor and clutch means which operatively connect said motor to the arm member, means for energizing and deenergizing said clutch means, the clutch when energized causing the arm member to rotate, and means for causing the arm and knife to stop at a predetermined position, said means including brake means operatively connected to the arm member, means for energizing and deenergizing said brake, said means including a cam mechanism mounted for rotational movement about an axis and a sensing mechanism, means for operatively connecting said cam member to the arm member so that the angular position of said cam corresponds to the annular position of the arm, means for positioning said sensing mechanism relative to the cam member so that it senses the position of said cam at a predetermined stop position, said sensing mechanism when energized adapted to transmit a signal to the brake when the cam member is at its predetermined stop position thereby energizing the brake, said sensing mechanism and brake being deenergized when the clutch is energized and said clutch being deenergized when the sensing mechanism and brake are energized.
