Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a new method for folding running paper for a rotary printing press.

Conventionally, as shown in Fig. 1, the method of folding the running paper of a rotary printing machine, such as a newspaper, is to print on both sides of a paper roll 1 of Kanayama (newspaper 4 shells) supplied from a paper feed section in a printing section 2, and then fold it. , Cut it in the center with the slick 3 to make a paper (newspaper 2 shellfish), overlap one running paper 5 □ with the other running paper % with the turn bar 4, and run while folding it vertically in half at the position of the triangular plate 6. The direction was changed, the cutter cylinder 7 cut it, and the folding cylinder 8 folded it horizontally to obtain one signature 9.

In addition, when it is necessary to fold two folds by stacking two e-folds, a rotary printing machine is added according to the number of copies, and after cutting the Kanayama-printed running paper 5 that is overlapped and run in the hand with a slitter 3, Each hand paper 5□, 5° is folded vertically in half using two triangular plates 6□, 6□ arranged horizontally with respect to the running direction of the paper, overlapped, and cut with a cutter body 7. It was then folded horizontally using the folding drum 8 to create a two-part folding book 9 (see Figure 2).
.

However, in newspapers, for example, news editions, home editions,
There are cases, such as entertainment editions, where it is necessary to fold the three types separately and then fold them together to form a single fold. It has been considered that the folding process requires a lot of effort and is unsuitable for folding in a rotary printing press, which requires speed, as it involves manually inserting and folding a separate folded form into the form.

The width of the lid and roll paper is the same for Kanayama, hand, etc., and the printing device for Kanayama's roll paper uses paper that is folded in three parts or more (i.e., paper that is more than full-thickness plus solder). It has been technically and standardly impossible to arrange three or more triangular plates and automatically fold them.

The present invention eliminates the conventional automatic folding method in which triangular plates are arranged horizontally in relation to the running direction of the running paper and folds the paper, and the present invention enables the running direction of the running paper consisting of a gold mine or a roll of paper in your hand to be folded. By appropriately changing the number of overlapping sheets using a turn bar, the paper is folded vertically using at least three or more triangular plates arranged sequentially in the vertical direction of the rotary press to form a plurality of signatures with different numbers of sheets. The present invention relates to a method for folding running paper for a rotary press, characterized in that a sheet is sent to a folding section and a folded bundle of three or more parts is automatically folded.

The present invention will be explained below based on the drawings of the embodiments.

Figures 3 and 4 show an automatic three-part folding method using three triangular plates arranged linearly in the running direction of paper. Web rolls 1, each sent to a printing press.

1□ and 13 are printed on both sides by the printing units 21, 22, and 23, and after being cut into solders by the slitters 3□, 3□, and 33, one of the solders on the running paper 51 is reversed by the turn bar 4 and superimposed on the other. Then, overlap one side of the solder on the running paper 5□ and
The sheets are stacked, and while being folded vertically in half using a triangular plate 6, the running direction is changed to the vertical direction of the rotary press, and the sheets are sent to the folding section 10.

Next, the remaining solder on the running paper 5° and one side of the solder on the running paper 53 are overlapped to form two sheets, and while folding this in half lengthwise with the triangular plate 6 Reorient it so that it is in the same direction as the paper and in front of it.

The remaining solder on the running paper 53 is vertically folded in half by the triangular plate 63 and changed so that the running direction is the same as that of the two sheets of running paper and located in front of it.

The half-folded 3-sheet stack, 2-sheet stack, and 1-sheet hand-running paper notebooks are stacked in the folding unit 10, cut by the cutter cylinder 7, and folded horizontally by the folding cylinder 8 to form a three-part folded bundle. is completed.

In this case, the paper folded by the triangular board 61 has 12 pages on 3 sheets, the paper folded by the triangular board 6□ has 8 pages on 2 sheets, and the paper folded on the triangular board 63 has 4 pages per sheet.

The embodiment shown in Fig. 5 shows a folding method when the height is too high when three triangular plates are arranged one above the other. is arranged linearly in the vertical direction, and another one 63 is arranged in a position opposite to the triangular plate 6□, and the running paper 53 is introduced by the tamper 4 in front of the triangular plate 62 in the running direction of the running papers 50, 52. The sheets are overlapped in the folding section 10, cut and folded to complete a three-part folded bundle.

The embodiment shown in FIG. 6 shows an example in which a solder web 1 is used from the beginning and a printing section 2 of a solder rotary press is used. In this case, too, the triangular plates 61, 6 It is arranged in a straight line.

Due to installation conditions, the triangular plate 63 is placed in a position opposite to the triangular plate 6□, and the turner 4 introduces the paper in front of the triangular plate 62 in the same direction as the running direction of the other paper sheets, thereby folding the folded bundle into three parts. Completion is the same as other embodiments.

This invention uses a method to sequentially introduce and stack each running paper that is folded into two by a triangular plate at a position in the running direction, cut and fold it, and thereby multiple folds such as 3-part folding and 4-part folding are possible. , it has the effect of being able to be completed automatically and efficiently.

Furthermore, if the configuration is as set forth in claim 2, the triangular plate attachment of the conventional rotary press can be easily completed by simply changing the position of the triangular plate.

When configured as described in claim 3, the triangular plate mounting of the rotary press has the effect of automatically and efficiently completing a three-part folding bundle without making the height too high.
