Abstract
1397864 Platen presses J BOBST & FILS SA 6 March 1973 [14 March 1972] 10699/73 Heading B6C In a sheet-fed platen press in which the sheets are carried on gripper bars attached to endless chains an apparatus is provided for maintaining the chain under tension. This apparatus comprises a source of pressurized hydraulic or pneumatic fluid 18, 17, cylinders 11, 12, connected with the source, a piston slidable within each cylinder and connected to the associated chain 1, 2, to apply a force to the chain whereby the tension of the chain is proportional to the pressure of the fluid and means for maintaining the pressure at a predetermined level whereby a constant tension is applied to the chain. A check valve 14 is provided to allow the pistons to move to the right when the chains are under increased tension. In a second embodiment the valve 14 is replaced by a cam controlled device.
