  • Carrier for a screen printing stencil
    Patent number: 5655445
    Abstract: The carrier of the screen printing stencil is mounted onto an auxiliary frame which holds the entire structure stable in the shape of a plate. Due to specific design of the longitudinal profile bars of the frame as bendible metal profile bars which return on their own into the outstretched shape, made e.g. of a springy sheet metal, a cylinder can be shaped from the relatively stable plate at any time.
