Akselin ympäri pyörivän, kehäuralla varustetun oikaisu- tai kalibrointirullan kiinnitys- ja irrotusmekanismi

摘要

The invention relates to a mounting and dismounting mechanism for a straightening or calibrating roller (2) rotatable about a spindle (1) and provided with a circular groove (13). The spindle (1) has its cavity (4) fitted with a pusher (9), having a tapered thrust face (9a, 9b) which shifts, as a result of the force of a spring (10), a holder element (8) from its release position to its clamping position. The holder element (8) is located in an opening present in a wall (3) of the cylinder (4). A plunger (11), associated with the pusher (9), can be used for moving the pusher against the force of the spring (10) to a position in which the holder element (8) is capable of shifting from its clamping position to its release position in which the roller is removable from the spindle (1) or mountable onto the spindle.
