  • Patent number: 4967655
    Abstract: The mounting of the flat flexible printing screen is such that printing stencils can be applied in a correct position and practically without distortion on the printing screens. The screens are then mounted in the correct position in a stretching of printing frame or on a rotatable printing cylinder. The printing screen is secured at opposite ends to stiffening profiles which can be clamped in clamping devices on the printing frame or printing cylinder and can be stretched by moving one of the clamping devices. The printing screen may also be similarly mounted on a copying frame and a transfer frame.

  • Patent number: 4940354
    Abstract: The mounting device for the squeegee or inking blade has an elastic clamping tube which can be expanded under a pressurized medium to clamp the squeegee or inking blade in place. The clamping tube is made of resilient material and ensures that the squeegee or inking blade is secured with a uniform linear pressure over the whole length. A spring may also be used to initially hold the squeegee or linking plate in place until the clamping tube is expanded.
