ABSTRACT:
An apparatus for spreading and depositing a viscous liquid or paste-like material on a substrate includes a housing removably insertable into a diamond- or square-shaped squeegee blade holder, the blade holder itself mounted to a squeegee head assembly of a screen or stencil printer. The squeegee head assembly is driven in a linear direction over and above the substrate, dragging the blade over the substrate and forcing deposition of the material onto the substrate. The housing includes a pair of oppositely-disposed locking clamps that attach to both ends of the housing. A shaft having a blade secured thereto is disposed through the channels of the clamps and within a groove of the housing, and the shaft is rotatable within the housing and the locking clamps so that the angle of attack between the blade and substrate can be selectively adjusted and, once the appropriate angle of application is selected, the blade is fixed in position by tightening the clamps against the shaft.
