Abstract

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.
