Screen printing method for transferring viscous product e.g. ink, involves transferring product in transfer zone, constituted by concave form plugged with elastic body, in which it is spinned, pressurized and scraped by scrapping edge

摘要

The method involves transferring a thixotropic viscous product (1) in a transfer zone constituted by a concave forme (15) plugged at its end with an elastic body. The forme is delimited at rear by a scrapping unit (9) contacting a mask (2), and at front by an isolation wall (14) allowing passage of the product from a supply tank towards the zone in which the product is spinned, evenly pressurized and scraped by a scrapping edge (6). An independent claim is also included for a viscous product transfer device by screen printing, for transferring viscous product on a substrate through a mask, by displacement of the device at the surface and related to the mask.
