ABSTRACT:
For operating the rollers and the steam chest in a laundry flatwork ironer a hydraulic system is provided which includes a hydraulic motor for driving the rollers, hydraulic cylinder-and-piston units for raising the steam chest, and a pump for operating the motor and the cylinder-and-piston units. Valves between the pump and the motor are selectively operable to establish low pressure standby operation of the pump with the hydraulic motor off, or low speed operation of the motor to jog the rollers or higher speed operation of the motor to drive the rollers at a speed appropriate for laundry flatwork. Other valves between the pump and the cylinder-and-piston units are selectively operable to raise the steam chest, reduce the cylinder pressure after the steam chest has been raised, and to increase the cylinder pressure whenever laundry flatwork is in the ironer.
