Abstract
A controlled deflection roll comprising a stationary support and a substantially tubular-shaped roll shell rotatable about said support. Between the support and the roll shell there are arranged a number of movable piston-like hydrostatic pressure elements having contact surfaces serving to support the roll shell. The invention contemplates providing the pressure elements with substantially flat side surfaces extending in the direction of movement of the pressure elements. The side surfaces of neighboring pressure elements disposed at the same side thereof are located in a common plane. In order to connect neighboring pressure elements there are provided connection components having resilient flaps or tabs which bear against the flat side surfaces of at least two neighboring pressure elements.

A controlled deflection roll comprising:
- a stationary support;
- a substantially tubular-shaped roll shell;
- means for mounting said substantially tubular-shaped roll shell to be rotatable about said stationary support;
- a plurality of movable substantially piston-like hydrostatic pressure elements located between said stationary support and said roll shell;
- said pressure elements including contact surface means which serve to support the roll shell;
- said pressure elements having substantially flat side surfaces extending in the direction of movement of said pressure elements;
- said side surfaces of neighboring pressure elements being located in substantially a common plane;
- connection means for connecting neighboring pressure elements;
- said connection means comprising resilient flaps which bear against the flat side surfaces of at least two neighboring pressure elements.
