Squeegee and scooping flow coater

A stencil fluid scoop and flow coating device for stencilling apparatus having a stencil screen and stencil screen supporting frame, both said screen and frame being reciprocable in one direction for a stencilling stroke and in an opposite return direction for a return stroke, and a squeegee support mount and squeegee extending transversely of said one direction, said mount and squeegee being vertically shiftable between a lowered stencilling position at said screen and an elevated nonstencilling position spaced above said screen;

• said scoop and flow coating device comprising a trough extending parallel to and spaced from said squeegee to the rear of said squeegee relative to said one direction;
• said trough being mounted independently of said squeegee;
• said trough having walls forming a cavity, and having an edge forming a flow coater for stencil fluid on said screen;
• said trough being pivotally shiftable independent of and spaced from said squeegee, to shift from a first flow coating position spaced from said squeegee with said cavity facing laterally and forwardly toward said squeegee in a fluid nonretention position and said edge forming a flow coater, through a fluid scooping motion with said trough edge serving as a fluid scooping edge when said squeegee is vertically elevated above said screen and said screen is moving in said one direction to scoop up excess fluid from the stencil screen and retain it in said cavity for the return stroke, to a second position spaced from said squeegee and with said cavity oriented upwardly to retain stencilling fluid therein as a vessell.
