A cylinder for machines processing running lengths of material is supported at its ends by bearing frames which may be moved for moving the cylinder, the cylinder having a pipe-like or tube-like outer casing which is supported by self-aligning bearings and has within it a core which is not turned and has an outer diameter smaller than the inner diameter of the casing, the casing being supported on the core by at least one support bearing which is symmetrical with respect to the middle of the casing and coaxial thereto. To give the casing a desired line of bending, to be in harmony with the cylinder with which it is used (on the other side of the running length of material) without being changed by moving the cylinder towards and away from the other cylinder, the pipe-like casing is supported in self-aligning bearings at its ends, separately from the core within it, on the end bearing frames. The ends of the core, running out from the pipe-like casing, are able to be moved by adjustment parts acting radially, such adjustment parts being supported on the two bearing frames. For prevention of any hot spots on the casing, the space between the casing and the core has an oil filling and on the core there are sloping blades for guiding oil towards the bearing or bearings by way of which the casing is supported on the core, this resulting in an even distribution of heated oil within the casing.

An impression cylinder for a printing machine having an impression and an etched cylinder, said impression cylinder including: (a) a cylindrical outer casing supported at its ends on said machine by first adjustable support means including self-aligning bearings, (b) a cylindrical core coaxially disposed in said outer casing and supported therein by at least one support bearing disposed symmetrically with respect to the center of said outer casing, the ends of said cylindrical core extending beyond the ends of said outer casing, (c) second adjustable support means engaging the ends of said cylindrical core which are supported on said first support means for separate independent adjustment, said second adjustable support means permitting radial adjustment of said cylindrical core independent of said outer casing, (d) an annular oil receiving chamber defined between said cylindrical core and said cylindrical outer casing partially filled with oil, said chamber being open with respect to said support bearing supporting said cylindrical core within said outer casing, and (e) at least one strip-off device associated with each support bearing, supporting said core within said outer casing, disposed laterally therefrom and secured to said core extending radially toward said outer casing to strip the oil therefrom during operation and direct the oil toward said support bearing, said strip-off device including an angled segment disposed symmetrically with respect to the cylindrical outer casing axis, the apex thereof directed toward the associated support bearing, said angled segment being contoured to said outer casing and said cylindrical core.
