ABSTRACT:
An apparatus for printing a viscous material onto a surface of a board through the medium of a screen having openings therein. The apparatus includes a viscous material dispenser of the type having a box-like housing in which a chamber for containing the material and a slit-like bottom aperture communicating therewith are provided. A pair of blades depend from the housing on opposite sides of the bottom aperture. A rear wall of the housing includes a fixed upper wall section and a height-adjustable lower wall section height-adjustably connected thereto. The lower wall section is connected to manually operable height-adjustable device mounted on the housing and for adjusting the height of the lower wall section having the squeegee blade so that by adjusting the height-adjustable device, the contacting pressure of the lower end of the squeegee blade to be applied against the upper surface of the screen can be adjusted as desired. The housing includes a pair of side walls each having a surface-contacting planar portion. The apparatus further includes a pair of supporting members each having a planar upper surface for supporting the screen from below and for bearing the dispenser at the surface-contacting planar portions of the side walls of the housing, through the intermediary of the screen supported on the planar upper surfaces of the supporting rail members, during printing.
