ABSTRACT:
A support device for a drum (1) which is provided with two journals (57, 59) projecting from the drum on either side of the drum, whose centerlines (25, 27) substantially coincide with the centerline (9) of the drum. Each of the two journals (57, 59) is journalled around an axis of rotation (61) in a bearing bush (63, 65) which is attached to a frame (67) by a ring-shaped membrane (69) positioned in a plane transverse to the axis of rotation (61). Each of the two journals (57, 59) forms part of a shaft (17, 19) projecting into the drum (1), and attached to a shell (7) of the drum by a ring-shaped plate (11). An end of a portion of each shaft (17, 19) projecting into the drum (1) bears on adjustment devices (41, 43, 49) by which the relevant shaft (17, 19) with journal (57, 59) can be swivelled relative to the centerline (9) of the drum (1). In particular, such a support device is used for a drum (1) which serves as a rotating carrier for a plate-shaped workpiece which is to be machined accurately by a cutting tool, such as, for example, a master for the production of projection television screens.
