STENCIL PRINTER Russian patent published in 1995 - IPC

FIELD: polygraphy. SUBSTANCE: printer comprise a frame-mounted vacuum table, a doctor mechanism and a stencil unit. The latter incorporates a base frame and a stencil holder. The stencil holder adjusting screws on the base frame are disposed in the holder plane and square to its plane. Each screw is installed on bracket with the aid of a key and a nut and has a support in the form of a shackle accommodating a plate connected to the stencil holder. Said plate is capable of moving inside the shackle in a plane parallel to the stencil holder plane. Installed between the stencil holder and the base frame are springs. Friction between the shackle and the plate is reduced by balls. In this case there takes place forced displacement of at least three holder points in the direction perpendicular to its plane and, consequently, of the stencil relative to the article. This adjusts its planeness and parallelism thus promoting the quality of print. EFFECT: improved design. 2 cl, 3 dwg
