Title:
孔版印刷装置の圧胴
Document Type and Number:
Japanese Patent JP4231119
Kind Code:
B2
Abstract:
A press roller for a stencil printer of the present invention is rotatable while pressing a recording medium against an ink drum which is rotatable with a master wrapped therearound. The press drum includes a hollow cylinder and an elastic layer formed on the outer periphery of the hollow cylinder. The elastic layer has a higher compressibility than a recording medium and performs, when compressed, elastic deformation in place of bulk movement. With this configuration, the press drum protects the master from damage ascribable to the localization of a pressing force. In addition, the press drum prevents a recording medium from creasing due to a difference in linear velocity otherwise occurring between the press drum and the recording medium at a pressing position.
