Abstract (en)

[origin: FR2782945A1] The invention concerns a capillary doctor blade with surface injection for liquid product (4) screen printing with viscous liquids on a substrate (1) through the orifices of a silkscreen (2). Said self-contained element is adaptable on direct transfer devices comprising a reservoir capable of being pressurised with a length corresponding to the substrate to be screen printed. The surface injection doctor blade comprises an elastically deformable capillary element (16) in contact with the silkscreen (2), preventing the product natural flow (4) when it is not subjected to the pressure (F2) and which allows a product flow matching the application requirements when the product is under pressure. Scraping lips (6a and 6b) oppositely inclined ensure that the device is sealed at the front and at the rear of the injection surface (10) while the ends are sealed by sealing foam blocks. The invention also concerns a work method for said surface injection capillary doctor blade.
