Abstract

A paper glazing calender is provided at each end with a double acting cylinder each of which is operative when a relatively high hydraulic pressure is applied to one side of the cylinders to lift the calender rolls, and when a similar high hydraulic pressure is applied to both sides of the cylinders to apply a relatively small nip pressure force to the rolls by virtue of the fact that the force applied to the pistons on each side thereof does not balance due to the surface area taken up by the piston rod on one side of the piston. There is an electro-hydraulic arrangement acting on the valves in the fluid conduits to ensure that the cylinders act in synchronism. To avoid the possibility of a high nip pressure being applied to the rolls if there is a fault in the hydraulic system, a non-return valve is provided in a conduit linking the two sides of the cylinders.
