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.

[ What is claimed:] [27.] A process for spraying liquid on the underside of a series of colorant applicators, which comprises:moving a liquid manifold, having a first end portion and a second end portion, and having a plurality of liquid jets underneath said series of colorant applicators and applying liquid under pressure from said plurality of liquid jets under pressure, wherein said first end portion of said liquid manifold is attached to a first trolley by means of at first pivoting joint and said second end portion of said liquid manifold is attached to a sliding joint that is attached to a second pivoting joint that is attached to a second trolley wherein said first trolley is moveably attached to a first track and said second trolley is moveably attached to said second track wherein said first track and said second track are attached to a frame that supports said plurality of colorant applicators and wherein said first track includes a first substantially horizontal track member, having a top portion and a bottom portion, and a first substantially vertical track member, having a top portion and a bottom portion, wherein said first trolley includes a first substantially vertical trolley member and a second substantially horizontal trolley member and wherein said first substantially vertical trolley member has a plurality of first rotatable cam followers attached thereto that engage said first substantially horizontal track member with at least one first rotatable cam follower adjacent to said top portion and at least one first rotatable cam follower adjacent to said bottom portion of said first substantially horizontal track member and wherein said first substantially horizontal trolley member has a plurality of second rotatable cam followers attached thereto that engage said first substantially vertical track member with at least one first rotatable cam follower adjacent to said top portion and at least one first rotatable cam follower adjacent to said bottom portion of said first substantially vertical track member for movement of said first trolley along said first track and wherein said second track includes a first substantially horizontal track member, having a top portion and a bottom portion, and a first substantially vertical track member, having a top portion and a bottom portion, wherein said second trolley includes a first substantially vertical trolley member and a second substantially horizontal trolley member and wherein said first substantially vertical trolley member has a plurality of first rotatable cam followers attached thereto that engage said first substantially horizontal track member with at least one first rotatable cam follower adjacent to said top portion and at least one first rotatable cam follower adjacent to said bottom portion of said first substantially horizontal track member and wherein said first substantially horizontal trolley member has a plurality of second rotatable cam followers attached thereto that engage said first substantially vertical track member with at least one first rotatable cam follower adjacent to said top portion and at least one first rotatable cam follower adjacent to said bottom portion of said first substantially vertical track member for movement of said second trolley along said second track.
