or screw bolts in one direction or the other, the height of the plate k can be adjusted in order to regulate the action of the springs í as well as the springs n.
By inserting the housing for the ball bearings into an open fork f, the pre-pressure roller can be easily and quickly inserted and removed, and to facilitate this insertion and removal, both pins e can be extended beyond the ball bearings and designed as a handle.
The rotation of the pre-pressure rollers h can be secured in a manner known per se by an auxiliary drive which, for example, can consist of a small disk o placed or fastened on the shaft a; The clamped disk is driven by a cord or the like.
PATENT CLAIMS:
1. Delimbed pre-pressure roller for paper machines, characterized in that the pre-pressure roller can be adjusted by springs, rubber buffers, oil cushions, air cushions or the like.
