ABSTRACT:
A bearing for supporting rolls of paper includes a pair of identical devices, each of which is formed of two telescopically coupled elements jointly forming an axially expandable cone. The free end of a first element has a flange to be connected to a member which is capable of rotating and reciprocating movement. Between the two elements is an expansion spring which maintains them in a position of maximum extension corresponding to an inoperative position. A surface of the first element is provided with a series of channels made according to the generatrix thereof, in which slide plates which can project through openings made in the side surface of the second element. The first element has an annular expansion acting as a support for one of the openings of a cylindrical tubular core on which a sheet of paper forming the roll is wound.
