Abstract:

A tension control system for a baling machine has a pressure switch connected to the high pressure fluid supply. The switch is operable to actuate when the pressure of the fluid supply exceeds a predetermined level, such as when the baling head ram cylinder is approaching a stalled condition. A solenoid controlled valve is located between the high pressure fluid supply and the fluid cylinder which operates the tension mechanism on the throat portion of the baling machine. The solenoid is operatively connected to the pressure switch to close when the pressure of the fluid supply exceeds to predetermined level. When the valve closes, fluid pressure in the tension cylinder is relieved so that the cylinder operating the baling head does not become stalled. When the baling head is again capable of operation, the pressure switch deactuates, returning the valve to an open condition so that tension is restored to the throat portion of the baling machine.
