After passing a plurality of continuous papers 3 which are printed and sent to the folding part in a state of being overlapped with b and 21c, these removable paper pressing rollers 21a, 21b and 21c are attached to the drag roller 2. When put in contact with each other, the paper pressing rollers 21a, 21b, 21c are attached to the corresponding arms 4a, 4b, 4c of the air cylinder 5 respectively.
A plurality of continuous papers 3 superposed on the outer peripheral surface of the drag roller 2 are pressed via the. Since the drag roller 2 and the paper pressing rollers 21a, 21b, 21c rotate in the direction of feeding the paper at a peripheral speed slightly higher than that of the plate cylinder, a plurality of rollers sandwiched between the drag roller 2 and the paper pressing rollers 21a, 21b, 21c are provided. The continuous paper 3 is pulled all at once toward the triangular plate 1 at the folding portion.

Also, the paper pressing roller 21
For normal newspaper printing, a, 21b, and 21c are non-printed portions that are margins outside the ruled lines of the newspaper, that is, FIG.
As shown in (A), it is disposed at both edges and the center of the width of the paper, and this pressing portion has the paper pressing rollers 21a, 21b, 21c as shown in FIG.
The continuous paper 3 on the outer peripheral surface is strongly pressed locally in a state close to line contact.

The number of cases of performing multicolor printing of page continuations is increasing. In this case, the paper pressing rollers 21a, 21b, 21c
As shown in FIG. 8B, when the paper pressing roller 21c at the central position is put on as shown in FIG.
The stamp surface at the center of the spread surface is strongly pressed by the paper pressing roller 21c against the outer peripheral surface of the drag roller 2 in a state of being locally close to line contact. As a result, the stamp surface becomes dirty and the quality of multicolor printing is seriously impaired. Therefore, in order to prevent the marking surface from being contaminated, as shown in FIG. 8C, the paper pressing roller 21c at the central portion is released, and only both edges of the paper width are pressed to operate.

After a plurality of continuous papers 3 sent from the paper feeding section of the rotary press through the printing section are overlapped with the outer peripheral surface of the drag roller 2, the paper is threaded,
When the paper pressing means 10 is put on the drag roller 2, the respective detachable air cylinders 5 are actuated,
The respective arms 4a and 4b descend and the drag roller 2
Pressing rollers 11 and 12 press the upper edge portions of the continuous paper 3 on the outer peripheral surface of the continuous paper 3 from above the pressing belt 14. Then, the surface of the pressing belt 14 between the pair of pressing rollers 11 and 12 is curved along the curved surface of the continuous paper 3a on the outer peripheral surface of the drag roller 2 between the positions P1 and P2, as shown in FIG. , A plurality of overlapped continuous papers 3 with respect to the outer peripheral surface of the drag roller 2 in a state of surface contact

Because it presses on a large area,
If the same pressing force as that of the conventional paper pressing roller 21a is given, the pressing force per unit area becomes extremely small, and a very large pressing force can be obtained by only slightly increasing the pressing force.

出すことができる。According to the paper drawing apparatus according to the first embodiment of the present invention, the paper pressing means 10 has a pair of front and rear pressing rollers 11 and 12, and these pressing rollers 11 and 12.
Since it has the pressing belt 14 wound around, it has the following effects. A roller system in which the continuous paper 3 on the outer peripheral surface of the conventional drag roller 2 shown in FIGS. 6 and 7 is strongly pressed locally in a state close to line contact, or a belt system in which only the pressing force of the pressing belt 34 shown in FIG. 10 is used. Unlike the holding means 10 of the present invention, the outermost continuous paper 3
Pressing the pressing roller 11 and 12 after the position P1 where a starts to follow the outer peripheral surface of the drag roller 2 and before the position P2 where it starts to separate from the outer peripheral surface, the continuous paper 3a between the positions P1 and P2 following the outer peripheral surface of the drag roller 2 is pressed. Holding belt 14
Since they are pressed in a surface contact state, a large pressing force can be obtained more easily than in the conventional method, and a large frictional force is generated on each contact surface. It can be pulled by force and sent out onto the triangular plate 1.

ことができる。Further, the continuous paper 3 wound around the outer peripheral surface of the drag roller 2 and running is provided with a pair of front and rear pressing rollers 11, 1.
Since it is strongly pressed and pulled by 2 and the pressing belt 14, it is not necessary to provide the paper pressing means 10 at the central position of the paper width as in the conventional case. Therefore, according to the present invention, even if there is a multi-colored printing surface with a large number of pages and a two-page spread using a wide plate on the two-sided spread surface, stains do not occur at the center of the two-sided spread surface, and a high quality The multi-color printing can be performed, and the quality of the multi-color printing on the spread surface of two consecutive pages can be improved and the folding accuracy of the multi-page printing can be stabilized.

同じである。After passing through the paper, when the respective paper pressing means 10 are put on and the first drag roller 2A and the second drag roller 2B are rotated, the number of the plurality of continuous papers 3 sent out from the printing unit becomes very large. Even when the number of sheets is large, the difference in peripheral speed between the inner and outer sheets due to the difference in sheet thickness is eliminated, and both the inner and outer sheets can be pulled by a stable sheet tension and fed onto the triangular plate 1. Therefore, in this embodiment, when the number of continuous papers 3 sent out from the printing unit is particularly large, there is an effect of simplifying the paper passing path, and the continuous continuous papers 3 with a stable paper tension are used for both the inner and outer papers. Since it can be pulled and sent out onto the triangular plate 1, there is an advantage that multi-page printing can be easily performed. The operation and effect of the paper pressing means 10 is the same as that of the first embodiment.

For example, as a result of experiments, it was confirmed that the continuous paper 3 can be sent out onto the triangular plate 1 by pulling the inner and outer papers of the continuous paper 3 with a stable tension even if the pressing belt 14 is not forcibly driven depending on the printing conditions. Therefore, the pressing belt 14 may not be forcibly driven in some cases. Further, the pair of pressing rollers 11 and 12 of the paper pressing means 10 may be replaced by three or more pressing rollers, and the oblong holes 15a. 16a may be provided continuously or along an arc concentric with the drag roller 2.
