ABSTRACT:
A device for cutting string cheese at a precise length as the string cheese is extruded. The device is comprised of a trip lever, a pivoting counterweight attached to the trip lever, a support bracket having an upper and lower stop to limit the movement of the pivoting counterweight, a plastic rod connected to the pressure release valve, the pressure release valve which operates the valve actuator when the pressure release valve is displaced from its rest position by the counterweight deflecting the plastic rod as the counterweight pivots, a valve actuator connected to an air supply, a valve connected to the valve actuator by tubing, a pneumatic cylinder connected to a valve by tubing and having a piston, and a knife attached to the piston of the pneumatic cylinder. When the desired length of cheese is reached, the weight of cheese on the trip lever activates the device causing the knife to intersect the path of the cheese and cut it. The support bracket rests on a pinion so that it may be vertically adjusted to allow any desired length of cheese to be cut.
