Printing machine cylinder holder arrangement

Claim 1

In a printing machine, a printing cylinder holding arrangement for holding in position a printing cylinder (3) to permit application of a cover sleeve (12) over the cylinder, wherein the cylinder has two shaft ends (4, 5) axially extending therefrom; wherein the printing machine has two side walls (1, 2) and two bearing means (21, 22) positioned in said side walls and rotatably retaining the shaft ends (4, 5) in the side walls, one side wall (1) permitting release of the associated bearing means (21) and being formed with an opening (6) of sufficient size to permit introduction of the cover sleeve (12) therethrough after release of the bearing means (21) retaining the respective shaft end (4) in said one side wall, said holding arrangement supporting the cylinder (3) in cantilever manner on the second bearing means (22) after release of the first bearing means (21), said second shaft (5) being elongated and forming a lever engagement arm, and comprising: a pair of structural elements (9') secured to that side wall proximate said second shaft end extending approximately parallel to the said second shaft end (5); an auxiliary shaft (10) extending transversely to said second shaft end (5) and positioned thereabove, said auxiliary shaft being eccentrically rotatably retained in said structural elements; locating means (11) on said auxiliary shaft determining the axial position of the auxiliary shaft with respect to the shaft end (5); means (17) for rotating said auxiliary shaft to permit engagement of the auxiliary shaft with said second shaft end, or release said second shaft end therefrom; and means (16 16'; 13, 14) for controllably axially positioning said auxiliary shaft (11) with respect to structural elements (9') and thereby position said locating means (11) and hence the second shaft end (5) in predetermined position to control the direction of cantilever projection of said cylinder (3).
