ABSTRACT:
In order to easily convert a lip rolling apparatus to different cup diameters, without involving a change of the phase relation of the roll feeds (1) relative to one another, two roll feed pairs are arranged oppositely, the roll feeds (1) of each pair being arranged at a fixed spacing (D1), individually, relative to one another, and the mutual spacing of the roll feed pairs is variable. The drive gears (10a,b, 11a,b) are adapted to be driven by a common drive belt (12) traveling over at least one deflection sheave (13a,b) arranged so as to be movable along the line of symmetry (40) between the drive gear pairs (10a,b, 11a,b). The drive gears (10a,b, 11a,b) have the same diameter as the deflection sheaves (13a, 13b) on a compensating knuckle (30a, 30b).
