PCT No. PCT/SE80/00183 Sec. 371 Date Mar. 11, 1981 Sec. 102(e) Date Mar. 11, 1981 PCT Filed Jul. 1, 1980 PCT Pub. No. WO81/00227 PCT Pub. Date Feb. 5, 1981.A turning roll assembly for the supporting and rotating of a cylindrical object (5) has two pairs of two rollers sets which are axially displaced in relation to each other. A supporting roller of each of the roller sets is rotatably mounted about a horizontal axis (23) in a holder (15,20) which is swivable about an axis (16) situated in a normal plane to the axis of rotation of the object. At least three holders (15,20) are each mounted on its carriage (3). The carriages are freely movable on a foundation in the direction of the axis of the object. The assembly is provided with a mechanism (25,27,29) for each carriage which converts an axial movement of the carriage (3) to a swivel movement of the holder (15,20) about its swivel axis (16). Thereby the foremost end of the roller axis (23) in the direction of movement of carriage swivels backwards in relation to the direction of rotation of the object. |
