Description

[Detailed description of the invention] This invention relates to an instrument for cutting paper products made with perforated cutting lines.

To explain with the drawing, the upper grip plate 1 and the lower grip plate 2 are connected by a strip with a spacing of several millimeters, and the inner surface of the upper grip plate has several ridges 5 perpendicular to the longitudinal direction. The rotary disk 4 is pivotally mounted near the edge between them with a few millimeters of the periphery protruding inward, and there is a step 7 on the inner surface of the lower grip plate from the center to the right.
Several ridges 6 are placed at right angles to the longitudinal direction, alternating with the opposing ridges 5, on the missing surface of about 1.2 mm.
A rotating disk hole 8 is bored into which a rotating disk matched with the rotating disk can be inserted.

When the upper and lower grip plates are squeezed, the cutout surfaces form a gap 9 for holding paper pieces, and the ridges placed alternately on the upper and lower sides allow paper pieces to be inserted in a wavy manner, making it easy to slide in a straight line, and stacking up. This is a cutter exclusively for paper products that uses a cutting machine to prevent the paper from bending into or coming off the rotary disk hole due to bending, and pulls the paper piece into a state in which it hangs in the air above the rotary disk hole.

To explain how to use it, align the perforation lines of the paper strip machined between the upper and lower grip plates with the rotating disc, squeeze the upper and lower grip plates to clamp the paper strip, and insert the periphery of the rotating disc into the cutting machine. , slide left and right along the perforation line to tear and cut the paper piece.

Paper products that have been processed with a cutting machine can be cut anywhere on a desk or in the air, using just the main end and no auxiliary equipment.

Can be used regardless of the length of the perforation line.

Postal items created by a computer office machine that separates stamps,
It is convenient for separating documents, etc.
