Abstract

A rotary screen printing press includes, a rotary screen cylinder (11) which supports a screen printing forme (11c) and is supported rotatably; an impression cylinder (13) which is provided to oppose the rotary screen cylinder (11), and is supported rotatably; and a squeegee (38) which is located within the rotary screen cylinder (11) and, during printing, contacts an inner peripheral surface of the screen printing forme, while being pressed against it, to transfer ink stored within the rotary screen cylinder (11) to a material (W) to be printed, which is held on the impression cylinder (13), via holes of the screen printing forme (11c). The printing press has a squeegee throw-on and throw-off control device (40A) which controls the pressing force of the squeegee (38) acting on the inner peripheral surface of the screen printing forme (11c) during printing in accordance with the type and thickness of the material (W) to be printed.

Description

Technical field [0001] The invention relates to a method and a device for adjusting the pressing force of a transfer liquid member of a rotary screen printing machine and other rotary stencil coating liquid machines. In addition, in the following description, for ease of understanding, the example cited is to use a rotary screen printer as a rotary stencil coating liquid machine, and use ink as the liquid to be coated on the object to be coated. The invention can also be used in the following liquid coating machinery, which uses a rotary screen coater instead of a rotary screen printer, and uses varnish to replace ink-coated stencils for other purposes. In addition, as a rotary stencil coating liquid machine, a machine for applying liquid on a sheet-like object has been described as an example. Of course, a machine for applying liquid on a roll paper can also be used. In addition, in the case of applying liquid on the roll paper, it is also possible to use a pressing roller with a...
