ABSTRACT:
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.
