Abstract
Abstract Three-dimensional objects are molded by advancing a special squeegee member along a flexible screen or the like to which a perforated mold is affixed, and pressing the mold into progressive engagement with a substrate, while at the same time, causing the squeegee to force the molding material through the screen and into the mold cavity, the mold stripping automatically and cleanly from the deposited material behind the squeegee as it is advanced.

Claim 1
Independent Claim
135 words
Screen molding apparatus comprising: a frame; a flexible member attached to the frame; a perforated mold joined to the member, said member having a portion at the perforation of the mold adapted for flow of molding material through the member and into the perforation; and means for flexing the member toward a substrate to move the mold into engagement with the substrate across the perforation and for simultaneously forcing said material through the member, into the perforation and onto said substrate, whereby to form a three-dimensional object conforming to the configuration of the perforation and substantially to the thickness of the mold, said means comprising an elongated, cylindrical element, longitudinally rigid, with the outer surface thereof formed of a resilient material, said element being provided with a member-engaging rib extending the length of said element.
