Abstract

PURPOSE:To attain to simplify the structure of the titled plate cylinder, by a method wherein a stencil paper attaching member for fixing one end part of stencil paper is constructed between a pair of flanges and both side parts of a fabric screen are fixed to flange outer peripheral parts while both end parts thereof are fixed to the stencil paper attaching member to provide said screen in a cylindrical form under tension. CONSTITUTION:A stencil paper attaching member 4 for fixing one end part of stencile paper is constructed between a pair of flanges 2, 3 and both side parts of a fabric screen 5 comprising polyester are fixed to the outer peripheral parts of the flanges 2, 3 while both end parts thereof are fixed to the stencil paper attaching member 4 to provide said screen in a cylindrical form under tension to form a plate cylinder 1. In the next step, ink 9 is supplied to the fabric screen 5 from an ink sump 8 by rotating an ink supply roller 6 and passed through the pores of screen stencil paper 10 wound around the outer peripheral surface of th fabric screen 5 in such a state that one end thereof is fixed to the stencil paper attaching member 4 to be transferred to printing paper 11 pressed to the screen stencil paper 10 through the gap between the fabric screen 5 and a press roller 7.

Description

【発明の詳細な説明】 技術分野 この発明は孔版印刷機の版胴に関する。[Detailed description of the invention] Technical field This invention relates to a plate cylinder for a stencil printing machine.

った。Prior Art The plate cylinder of a conventional single-cylinder stencil printing machine has a porous cylindrical body with a rigid structure such as a shield installed between a pair of 7272 plates, and a fine mesh wire mesh is placed around the outer periphery of this metallic porous cylindrical body. It had a structure made of woven cloth or a winding screen.

の電鋳によって面接に継目なしの薄い円筒状の版胴を得
るものなどが知られている。The manufacturing method for porous cylindrical bodies as described above generally involves machining a large number of holes in a thin plate of stainless steel or other material by chemical etching and rolling it into a cylindrical shape, or by electroforming nickel or other material to create a seam on the surface. One is known that produces a thin, cylindrical plate cylinder without a plate cylinder.

上記従来の版胴は、多孔質円筒体の加工に多くの工数と
高価な設備等を必要とし、版胴のコストアップの要因と
なっていた。The conventional plate cylinder described above requires many man-hours and expensive equipment to process the porous cylindrical body, which causes an increase in the cost of the plate cylinder.

となっていた。Furthermore, even if a large number of holes are formed in a thin plate, there are limits to the size and pinch of the holes in terms of strength, and it is difficult to obtain high-quality images because the hole ratio cannot be made too high. As a countermeasure, generally, the number of woven cloth screens is increased or a wire mesh screen is installed in the mJ between the rigid cylinder and the fa cloth screen to prevent imB failure from occurring. However, this was also a factor in increasing costs.

Both ends are attached (td) to both ends of the base paper mounting member 4, and the flanges 2,
3, Lla: A cylindrical plate cylinder 1 is formed by a mounting portion 4 and a woven fabric screen 5.

６が配設されており。When the plate cylinder 1 is attached to the printing press body (not shown), the ink supply roller 2 is placed in the plate cylinder 1 so that the axes thereof are parallel to each other while in contact with the inner peripheral surface of the woven fabric screen 5.
6 are arranged.

In synchronization with the rotation of the ink supply row 26, the plate cylinder 1 is also rotated by a drive device not shown. Furthermore, the ink supply roller 6 is inserted between the woven fabric screen 5 and
A press row 27 is installed at a position opposite to the press row 27 so that its axis is parallel to the plate cylinder l and the shaft grip of the ink supply roller 6, and is movable up and down. The woven fabric screen 5 is compressed by the woven fabric screen 5. The press roller 7 is also rotatable around its axis.

The stencil paper 10 is supplied through the hole in the stencil paper lO, which is fixed at one end of the JQ target number mounting member 4 and wound around the outer peripheral surface of the woven fabric screen 5, and passes between the woven fabric screen 5 and the press row 27. The image is transferred to the printing paper 11 which is pressed by the user. In this way, stencil printing is performed.

効　　　　果 以上のようにこの発明は、版ＨＦＩの円筒部を織布のみ
で構成したことにより、梃来のように。Effects As described above, this invention has a unique effect because the cylindrical portion of the HFI plate is made of only woven fabric.

多孔質円筒体を用いる必要がないので、版胴構造を簡素

優れた効果を有するものである。Since there is no need to use a porous cylindrical body, the plate cylinder structure can be simplified and the cost of the plate cylinder can be reduced, which is an excellent effect.
