ABSTRACT:
An automated screener in which print and flood squeegees are sequentially driven across a stencil screen framed in a chase. After a print stroke, the print squeegee is retracted and the chase is raised a short distance to make contact with the flood squeegee, which is driven in a flood stroke, whereupon the chase is raised further to an open position for removal of the stenciled workpiece. Means are provided for adjusting the print and flood squeegees and for limiting upward movement to predetermined levels during operation of the screener. Particular details relate to an arm carrying the print and flood squeegees over the chase screen. To prevent relative vertical movement between the chase and arm, both are pivoted around a common axis. Translation of the arm across the chase is accomplished by connection to a motor drive chain by means of a hingedly connected pin bearing member which permits the arm to be readily released from the chain when the arm is swung away from the chase.
