  • Patent number: 4907505
    Abstract: A device for securing and/or registering the stencil frame for a screen printing machine, said screen printing machine having amongst other things a printing table and a scraper and/or ink application device arranged above the printing table. Between the printing table and the scraper arrangement are arranged one or more guides (6, 7) intended to interact with the stencil frame (5). These guides are designed in such a way that the stencil frame (5) is able to be moved or displaced as a single unit from an initial position outside the screen printing machine to an appropriate position inside the screen printing machine, and vice versa. Inside the screen printing machine are present registering devices (8, 9) intended to guide the stencil frame into a registration position. The elements intended to interact with the stencil frame comprise at least two guides (6, 7) running parallel to each other, along which the stencil frame (5) is capable of being displaced.
