A supporting or intermediate roll in rolling mills for rolling flat rolling stock, in particular strip material, having a cylindrical roll core and a tubular sleeve which is connected in a rotationally fixed manner to said roll core, engages coaxially around the same and between which and the roll core there are arranged hydraulically axially displaceable supporting bodies which support the roll sleeve against the roll core. In this case, the supporting bodies are formed with at least two annular pistons, which are arranged symmetrically in relation to the roll center and are sealed in relation to the roll core and the inside of the roll sleeve, and include a plurality of annular supporting bearings, which are arranged on the outer circumference of the pistons, are spaced apart from one another in the longitudinal direction of the roll and against which the inner surface of the roll sleeve can be positioned.

Back-up or intermediate roller for producing a flat rolled product in a rolling mill

A rolling mill with working rolls and with multipart support rolls. The rolling mill includes of a basic body with a plurality of rolling bearings which are arranged next to one another on the basic body in its longitudinal direction. The outer rings of the bearing rotatably support a sleeve which surrounds the rolling bearings and bears with its inner surface, all-round, on the outer surfaces of the outer rings of the rolling bearings and the outer surface of which forms the roll barrel of the support roll. Three rolling bearings, of which the middle rolling bearing is designed as a tapered rolling bearing, are provided over the length of the basic body. In this case the two outer rolling bearings are designed as cylindrical roller bearings and an eccentric bush motively rotatable about the longitudinal axis of the basic body is arranged between the two cylindrical roller bearings and the basic body.

Rolling mill with working rollers and multipart support rollers

An arrangement for cutting sheet metal, particularly sheet metal strips. The arrangement includes a double cutting tool with two outer knives and an inner knife which is movable between the outer knives so as to form two cutting gaps. The outer knives are adjustable relative to each other by adjusting wedges in order to adjust the cutting gaps such that the two outer knives are adjusted by the adjusting wedges synchronously or asynchronously by either the same or a different extent. The two outer knives can be clamped against the adjusting wedges.
