Brief description of embodiments of deposits of viscous product and / or pasty on a substrate through the openings of a silk-screen printing stencil and dispenser device of the product

摘要

There may be one or more seals (15) which are inclined to make an angle (A) with the stencil between 120 deg and 180 deg within the opening and are placed at right angles to the displacement (F2) of the receptacle (6). The receptacle is mounted on a printing machine and it may be displaced in one direction then the other to remove excess material. The width of the opening is less than that of the receptacle and its length is adapted to that of the substrate on which the deposition is made. Pressure is applied to the matter by a piston (10). A removable grid (17) with openings comprising 20-90% of the area may be placed in the receptacle.
