複雑となり、作業に手間を要し効率が悪い欠点がある。(Prior art known technology) For example, in the past, as shown in Japanese Patent Publication No. 56-7845, the cutting and crimping operations of the binding bin were performed separately, which required a cutting device and a crimping device, resulting in a complicated structure. This has the disadvantage that the work is labor-intensive and inefficient.

て破損するなどの欠点の生じる虞れがあった。As shown in FIGS. 9 and 10 of the reference, the side-turned bottle is pressed against the paper by the arc-shaped recess 62 and the push plate 23, so that the tip of the bottle forms an arc-shaped bulge. Therefore, when bound sheets are stacked, not only are gaps created and the volume increased, but the bins are not tightly fixed to the documents. As a result, the tip of the bottle was exposed, and there was a risk of injury to fingers while handling the exposed bottle.Also, since the bottle did not fit tightly, there was a risk of problems such as paper rubbing and damage. .

3a is in the vertical direction, and its tips are each curved inward to form curved portions 4, 4a and a blade portion 4b at the tip. An inverted trapezoidal fixed cutter 5 is installed at the lower stage of the rotary cutter, an inverted U-shaped bottle 8 is inserted into the marginal hole 7 of the perforated computer paper 6, and the upper side of the bottle is pressed with a pressing plate 9 provided at the upper stage. At the same time, the rotary cutters 2 and 2a are rotated, and the fixed cutter 5 cuts the bottle 8 to the required length. Another marginal hole 10.
Press fit into 10a.

form b. Fixed cutter 5 below the rotary cutter
and marginal hole 7 of computer paper 6.
A pressing plate 9 is provided on the upper stage to press the binding bin 8 to be inserted. Therefore, the binding pin inserted into the marginal hole is cut to the required length by a rotating rotary cutter and a fixed cutter, and the lower end of the bottle is cut by the vertical side 3 of the rotating cutter.
3a and the curved end of the bottle is pressed into another marginal hole 10.10a inside by the clamping force of the vertical side of the cutter and the pressing plate. Each cutter position is set so that the bottle is cut to the required length. Further, the rotating disk is connected to a motor 12 via a known gear 11 that meshes with the rotating disk.
Rotate with.

等多くの利点を有するものである。Effects As shown in the above structure, the present invention is very efficient because the cutting and caulking operations are performed in a continuous process. Next, the tip of the rotary cutter is curved so that the tip of the cut bottle has an arc shape, and the tip of the curved bottle is of a required length that can be press-fitted into another marginal hole. It does not expose the bottles and injure your fingers, and instead of crimping with bottles bent in an arc, the vertical sides are bent horizontally and crimped with the horizontal plane, making it a very stable crimping process. It also has many advantages such as not increasing the volume excessively.
