CONSTITUTION:There are provided a pair of original folding rollers 13, 13' adjacently positioned together in parallel, a pushing-in member 15 which is extendable from and retractable into a slit 13b that is opened to the peripheral surface of the roller 13 in parallel to the axis of thereof, and a depressing member 21 which is disposed in a slit 17 that is opened to the outer peripheral surface of the roller 13' in parallel to the axis of the roller 13' and which may approach and move away from one inner side surface of the slit 17. That is, the member 15 pushes an original which is continuously fed, into a space between the inner surface of the slit 17 and the depressing member 21 when the pushing-in member 15 opposes the slit 17. In this zigzag-folding machine, the pushing-in member 15 is disposed in the roller 13 in such a way that the member 15 may be linearly extends from and retracts into the slit 13b in the radial direction of the roller 13.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention involves a pair of folding rollers νC that folds and discharges base paper that is continuously fed from a roll 7'1, and folds and discharges the base paper that is folded and discharged. This invention relates to a zigzag folding roller for a zigzag folding machine that creates origami paper products by cutting and separating from the center of a tube.

Conventionally, both sides of the base paper fed out from the base paper Ω-ru are continuously folded nine times in the width direction.

Next, this base paper 1 is continuously fed through the rollers 2 as shown in Figure #11, and a pair of folding rollers 5,
Fold this base paper 1 into a pair on 3' 7! (fc roller 5

The folding a-ra 3, 3'Fi used in this case.

As shown in Fig. 2, both a-ra circumferential surfaces are 3 m, ! The pushing member 7.8 which is bent and retracted from the tip end 7a * 8at which protrudes and retracts from 'a' and the pushing member 7 or - The single-sided fat member of the base paper 1t-slit 9 or 1jlO that is pushed in has a clamping member 11 or 1j12 that presses and clamps the base paper 1t-slit 9 or 1jlO, and the pair of rollers 3.5'
rotate in opposite directions to each other so that, for example, the pushing member 7 of the roller 3 faces the slit 10 of the roller radar. When this happens, the pushing member 7 pushes the continuously supplied base paper 1 between the slit 10 of the roller 3' and the suppressing member 12 at the tip l57.
m is pushed in, then the base paper 1 is sulin) 10 one side 1
At 0111, the pressing member 12KxD is pressed and clamped and folded, and as the pair of rollers 3 and 5' rotate, the pressing member 12 rotates by a predetermined angle.At O, the base paper 1 is pulled by the pressing member 12, and the pressing member 12 rotates by a prescribed width. The base paper 1 is then pulled out from the holding member 12.

In such a zigzag folding machine, since the pressing force acts only on the bending side tips 7@ of the pushing members 7 and 8 and the portions protruding from the rollers 3.3' of Bm, the bending side tips 7&*''
If & is long in the radial direction, the pushing member tends to bend due to the above-mentioned pressing force, and there will be cases where it will not be possible to reliably push the slit 10 [[[]].
Therefore, as a countermeasure, when the pushing member 7.8 is formed using a material tube having a certain thickness, t1, and having elasticity with a length of 1 m, the above-mentioned deflection of the pushing member 7.8 will be eliminated. Since the pushing member 7#e1 is formed of a thick member, the pushing member 7#e1 is made of a thick material. a-5 The base paper 1 is held by the pushed bale, and the gripping force of the base paper 1 by the suppressing member 11.12 becomes weak, and the roller 5. If you try to increase the number of folds of the base paper 1 by rotating it at a high speed higher than the lf-chamber, the base paper 1 will become slender and cannot be folded properly.

The roller 3. The number of folds of base paper 1 due to s′ is large @
was limited to.

The present invention solves the above-mentioned problems and solves the problem by installing the pushing member on the folding roller so that it can be linearly retracted from the first slit in the radial direction. By reducing the protruding portion so that even a thin member can withstand the pressing force of the suppressing member, and by making the pushing member thinner, the pushing member reliably pushes the base paper into the slit. This is a book that provides a roller for a 7t zigzag folding machine that allows the number of folds of the base paper to be increased by allowing the suppressing member to fold the YC base paper 1.

In this way, the base papers 1 are folded in a zigzag pattern one after another and are discharged to the discharge section 4. As a result,
Conventionally, one tube of base paper could be folded only when the rotation of the roller was 150 to 200 [Yellow, P, M), but the roller for the zigzag folding machine of the present invention has a machining of about 400 [[, P, M],
So... it can also be folded.

As is clear from the above, the roller Fi for a zigzag folding machine of the present invention and the pushing member are folded so as to be retractable in the radial direction from the first nullit. Attached to the river roller, the protruding part of the pushing member from the roller circumferential surface is reduced so that even a thin member can withstand the pressing force of the suppressing member.Thus, the thinning of the pushing member allows the pushing member to be used securely. The effect of the folding is that the base paper is pushed into the base paper, the suppressing member can fold the pressed base paper 1, and the number of folds of the base paper can be increased.
