ABSTRACT:
A screen printing machine for a web intermittently pulled forwardly to receive a succession of closely interspaced prints, has a printing table over which the web is intermittently pulled beneath a printing screen which contacts the web, and during each web stop a printing material knife is reciprocated over the screen to force printing material through the screen onto the web to make a print. A just-printed print can be pulled forwardly under the screen which to accommocate the deceleration and acceleration of its knife, extends forwardly beyond its printing area, so it is possible that still-wet print can be smudged by the screen contact. To prevent this, the printing table is provided with a slot down through which the web can pass so it does not contact the screen beyond the latter's printing area.
