Abstract
A printing cylinder for printing machines comprising a shaft, a sleeve adapted to support a printing block and mounted on the shaft with radial clearance, and an adjusting mechanism provided at each end of the sleeve. Each adjusting mechanism comprises a guide ring and a clamping ring having cooperating conical guide surfaces. A fit between the shaft and the guide ring is so easy that the guide ring may be somewhat tilted relative to a plane at right angles to the longitudinal axis of the shaft, and the clamping ring comprises radial, adjustable securing means and axial adjusting means, whereby it is possible to center the sleeve very precisely relative to the shaft.
Claims10
A printing cylinder for printing machines, particularly flexoprinting machines and indirect photogravure printing machines, comprising a shaft (1), a sleeve (2) adapted to support a printing block and mounted on the shaft (1) with radial clearance, and two adjusting mechanisms (3), said adjusting mechanisms including a respective adjusting mechanism (3) provided at each end of said sleeve (2), each adjusting mechanism (3) being adapted to centre and secure the sleeve (2) on the shaft (1) and each comprising a guide ring (7) and a clamping ring (8), said guide ring (7) being provided with a circumferential conical guide surface (9) engageable with a corresponding circumferential conical guide surface (10) at each end of the sleeve (2), characterized in that a fit between the shaft (1) and the guide ring (7) is so easy that the guide ring (7) may be somewhat tilted relative to a plane at right angles to the longitudinal axis of the shaft (1), and that the clamping ring (8) comprises radial, adjustable securing means (11, 12) for securing said clamping ring to said shaft and axial adjusting means (13, 14, 15) for adjusting said guide ring.
