PERFORIERTE SIEBDRUCKSCHABLONE ZUM AUFBRINGEN UND DOSIEREN VON MEHR ODER WENIGER DICKEN SCHICHTEN EINES VISKOSEN PRODUKTES

摘要

The present invention concerns a stencil for the depositing and gauging of more or less thick, point-base coats of a viscous product.To remedy the problems found with a serigraphic screen made of polyester or metal cloth and a metal stencil, the present invention proposes use of a solid sheet of uniform composition made of synthetic material and, preferably, polyester without the inclusion of wires. This polyester solid sheet is bored mechanically or thermally at the places desired. Since the polyester cloth is solid, it admits of tension forces greater than those of wire mesh cloths or at least equal to those of metal stencils.
