Guiding roller for calenders

Claim 1

A guiding roller structure, which includes: a shaft having a pivot at each end, a plurality of substantially axially aligned tubular mantle sections surrounding said shaft and being rotatably supported thereby, said tubular sections extending over the major portions of the length of said shaft and their outer surface forming the guiding surface of said guiding roller structure, each of said pivots of said shaft adjacent the outer ends of the end mantle sections having two substantially plane and parallel guiding surfaces located opposite each other, bushing means respectively arranged around said pivots, each of said bushing means having its inside provided with two substantially parallel sides longer than that diameter of the pertaining pivot which is located in that plane of symmetry of the pertaining pivot which is parallel to said parallel guiding surfaces thereof so as to permit a relative displacement of said bushing means with respect to the pertaining pivot, two selfaligning antifriction bearing means respectively interposed between said bushing means and the adjacent end portion of the respective adjacent tubular section for rotatably supporting the latter, and actuating means respectively associated with said bushing means and operable independently of each other from the outside of said roller structure for effecting a relative movement of said bushing means with respect to the pertaining pivot to thereby adjust the respective adjacent end portion of the respective adjacent tubular section relative to said shaft.
