摘要： A press comprises two cooperating endless belts each trained over a support and tensioning roller. The end supports of the support roller for the lower belt rest on a hydraulically actuated piston which enables this support roller to be displaced towards the other support roller. Two pairs of like bracing members hold the end supports of the support rollers, the bracing members of each pair having one end pivoted to a respective hydraulic cylinder for the pistons and the end supports of the other support roller being detachably fixed to the other bracing member ends. Each pair of bracing members defines a guide for the displacement of the end supports of the support roller for the lower belt. One of the end supports of each support roller is pivotally mounted for pivoting the support rollers in a plane defined by the axes of the support rollers.

摘要： In an apparatus wherein an endless band is trained over a stationary guide roll and a stretching roll, and a nut-and-spindle mechanism at the ends of the stretching roll can displace the stretching roll in a plane defined by the axes of the rolls when the band is centered on the rolls, the band is automatically centered by two hydraulic double-acting cylinder-piston units. The first unit displaces either end of the stretching roll in the plane and the second unit simultaneously displaces one end in a plane perpendicular thereto. This displacement is effected in response to a control signal from a sensor adjacent each side edge of the band and tripped when the side edge moves into contact therewith as the band moves out of its centered position. The control signal operates a three-way solenoid valve in a hydraulic control circuit for the cylinder-piston units.

摘要： A hydraulic device for producing a to-and-fro movement of a lever connected to a double-acting piston/cylinder unit comprises a pressure fluid distributor including a control piston for alternately feeding pressure fluid to one or the other side of the piston in the unit to move the lever alternately in opposite directions. A hydraulically actuatable control device for controlling the distributor includes a reciprocable piston member movable in a cylinder and a motion transmitting member in contact with the control piston of the distributor to transmit motion thereto. The piston member has a central large diameter section between two reduced diameter sections and the motion transmitting member is in contact with the surface of the piston member so as to reciprocate transversely in the cylinder when the piston member moves relative to the motion transmitting member between two end positions. The control device also includes an independently actuatable single-acting piston movable into a position where it holds the piston member with its large diameter section registering with the motion transmitting member.
