BACKGROUND OF THE INVENTION
The present invention relates to a stencil printing apparatus using a master base paper roll in which a long master base paper is wound in a roll shape.
[0002]
[Prior art]
Conventionally, a plate making for making a master by storing and holding a master base paper roll in which a long master base paper is wound in a roll shape, and heating and perforating the master base paper drawn from the storage and holding portion. There is widely known a stencil printing apparatus for printing by winding a master made by a plate making unit around a porous cylindrical plate cylinder.
[0003]
A master base paper used in such a stencil printing apparatus is formed by superposing a porous support such as Japanese paper or synthetic fiber and a thermoplastic resin film. In the plate making section, the master is made by subjecting the portion of the thermoplastic resin film on the master base paper to heat fusion perforation with a thermal head.
[0004]
When the master made in this way is wound around the outer peripheral surface of the plate cylinder and printing is started, the ink supplied to the inside of the plate cylinder passes through the opening portion of the plate cylinder and the porous support in the master. Bleeding from the perforated portion of the thermoplastic resin film in the master. Then, by rotating the plate cylinder while pressing the printing paper against the master wound around the outer peripheral surface of the plate cylinder, the ink exuded from the perforated portion of the thermoplastic resin film is transferred to the printing paper, and printing is performed.
[0005]
The fibers of the porous support in the master base paper are not uniform, and there are portions with high fiber density or thick fibers. If thick fibers or high fiber density parts overlap the perforated part of the thermoplastic resin film, the amount of ink oozed out from the perforated part will be reduced, and a fiber pattern will appear in the solid image part, and letters and fine lines may be blurred. Inconvenience occurs.
[0006]
Therefore, in order to prevent the occurrence of such inconvenience, there is a tendency for master base paper having a thin porous support and master base paper made of only a thermoplastic resin film without using a porous support.
[0007]
By the way, when the master base paper has jammed in the plate making section, after performing jam processing to remove the jammed portion, the master base paper is cut along the width direction using scissors, a cutter knife, etc. Is set so that it can be supplied to the plate making section.
[0008]
[Problems to be solved by the invention]
When the master base paper is cut along the width direction after the jam processing or the like, the cut portion may become oblique or jagged. When the cut portion of the master base paper is slanted or in a jagged state, the leading edge of the master made from the master base paper is slanted or in a jagged state. If the leading end of the master is slanted or jagged, the clamping state becomes poor when the leading end of the master is clamped by a clamper provided on the plate cylinder. When a master with a poor clamping state by the clamper is wound around the outer peripheral surface of the plate cylinder, the master is likely to generate undulation, deflection, skew, and the like. If the master wound around the outer surface of the plate cylinder is wavy, bent, skewed, or the like, the master is wrinkled when the plate is brought into close contact with the outer surface of the plate cylinder. The quality of an image printed using is reduced.
[0009]
When the master base paper is cut with scissors, a cutter knife, or the like, the fact that the cut portion becomes slanted or jagged becomes conspicuous as the waist of the master base paper becomes weak. For this reason, master base paper with a thin porous support or master base paper made of only a thermoplastic resin film without using a porous support is weak, so when cut with scissors, a cutter knife, etc. The cut part tends to be slanted or jagged. And it becomes easy to generate | occur | produce a wavy, a bending, a skew, etc. for the master wound around the plate cylinder by it.
