STENCIL FOR DEPOSITING AND PORTIONING VARIOUSLY THICK SPOT LAYERS OF A VISCOUS MATERIAL FOR ADDITION AND DISTRIBUTION OF SPOT LAYERS OF VARIOUS THICKNESS OF VISUAL MATERIALS

摘要

The present invention relates to a stencil for attachment and gauge of a rather thick point-based coat of a viscous product. In order to cure the problems found with a serigraph screen made of polyester or metal cloth and metal stencils, the present invention is directed to the use of a synthetic material, preferably a solid sheet of polyester, . The polyester solid sheet is perforated mechanically or by heat at the desired location. Because the polyester transition is solid, the tensile force is greater than the wire mesh cloth or at least equal to the metal stencil.
