Apparatus for moving the knives relative to their rotary holder in a tobacco cutting machine has a crankshaft which is rotatable and is rotated once during several successive revolutions of the holder. The crankshaft is the input element of a step-down transmission whose output element is a ring gear meshing with pinions for transmission of motion to discrete displacing units, one for each knife. The ring gear is rotated at intervals by a gear which is coaxial with a freewheel. The latter is rocked back and forth by a lever which is pivoted by the crank pin of the crankshaft by way of a rod-like connector. One end portion of the connector is coupled to the lever by an adjusting device which can change the extent of pivotal movement of the lever and hence the extent of rotation of the ring gear whenever the lever is pivoted in one of two directions.
Rotary cutting apparatus for use in a tobacco cutting machine adapted to compensate for knife wear, comprising at least one knife which is mounted on and is movable with respect to a rotary holder, a transmission mounted on said holder and having input means comprising a rotary crankshaft, means for rotating said crankshaft to response to rotation of said holder, output means including a rotary element, and motion transmitting means for intermittently moving said output means in response to movement of said input means, said motion transmitting means including a pivotable member, means for pivoting said member in first and second directions in response to rotation of said crankshaft and means for driving said rotary element in response to the pivoting of said member in said first direction;
