Abstract
This Invention is a method and apparatus for spraying water on the underside of a series of colorant applicators in order to rinse excess colorant from the machine parts. There is a water manifold having a first end portion connected to an upper trolley by a pivoting joint and a second end portion attached to a lower trolley by both a pivoting joint and a sliding joint. Both the upper and lower trollies are constrained in the horizontal, vertical, and rotational direction by a series of cam followers. The extra degrees of freedom provided by the two pivoting joints and the sliding joint insure that no binding occurs. An optional feedback control system can be added utilizing a rotational position transducer to sense the angle of the water manifold so that the motion of the trolleys can be retarded or advanced accordingly.
