ので、作業能率が向上する。(Function) The printed running paper transfer device for a folding machine of a rotary printing press according to the present invention is configured as described above, and the working efficiency is improved. That is, when a printed running paper with a fold formed on one side edge is transferred from one folding machine system to another folding machine system, the printed running paper comes into contact with the transfer roller. At this time, if the radius of the transfer roller is equal throughout the axial direction, the tension of the printed running paper becomes uneven in the axial direction, causing wrinkles, deviation, meandering, etc. in the printed running paper. This phenomenon occurs as the transfer speed of the printed running paper, that is, the printing speed, increases.
Although this is noticeable and prevents normal operation, in the printed running paper transfer device for a folding machine of the present invention, the small diameter of one roller that comes into contact with the thicker one side edge fold part of the printed running paper is A section is formed on one end side in the axial direction of the transfer roller, and a section 1 that contacts the other side edge of the printed running paper, the paper thickness of which is thinner than the fold section.
two roller large diameter portions are formed on the other axial end side of the transfer roller, and the radius of the roller small diameter portion including the folded portion is approximately equal to the radius of the roller large diameter portion including the other side edge. The difference in paper thickness in the width direction of the printed running paper is evened out by the large and small diameter portions of the roller, making it almost uniform, so wrinkles can be eliminated from the printed running paper without reducing the operating speed of the entire rotary printing press. , deviation, meandering, etc. do not occur. In addition, the transfer roller is placed upstream of the folding cylinder so that the wrapping angle of the printed running paper around the transfer roller is small, allowing smooth transfer from one folding machine system to the other folding machine system. This improves work efficiency.

部で行えばよい。 Next, the operation of the printed running paper transfer device for the folding machine of the rotary printing press shown in FIGS. 1, 2, and 3 will be explained in detail. When transferring the printed running paper 1 with the folded portion 19 formed on one edge side from the folding machine A system to the folding machine B system, the printed running paper 1 has a small winding angle α, β.
The transfer rollers 14 and 15 are brought into contact with the transfer rollers 14 and 15. At this time, if the radii of the transfer rollers 14 and 15 are equal throughout the entire axial direction, the tension of the printed running paper 1 becomes uneven in the axial direction, causing wrinkles, unevenness, etc. in the printed running paper 1.
Meandering etc. occur. This phenomenon occurs when the printed running paper 1
The faster the transfer speed, that is, the printing speed, the faster the
This is noticeable and prevents normal operation, but in the printed running paper transfer device for a folding machine of the present invention, one roller that comes into contact with one side edge folding portion 19 of the printed running paper 1 where the paper is thick The small diameter portion 22 is transferred to the transfer roller 1
4, 15 and 14', 15' in the axial direction, and one roller large diameter part 21 that contacts the tongue part 20 of the printed running paper 1 whose paper thickness is thinner than the folded part 19. Transfer rollers 14, 15 and 1
4', 15' on the other end side in the axial direction, and the folded part 1
The radius of the roller small diameter portion 22 including 9 and the tongue portion 20
The radius of the large diameter portion 21 of the roller containing the rollers is approximately equal to the radius of the large diameter portion 21 of the roller, and the difference in paper thickness in the axial direction of the printed running paper 1 is equalized by the large and small diameter portions 21 and 22 of the roller.
Since the printing is substantially uniform, wrinkles, deviations, meandering, etc. do not occur in the printed running paper 1 without reducing the operating speed of the entire rotary printing press. Further, the transfer rollers 14 and 15 are arranged upstream of the folding cylinder 10 so that the wrapping angles α and β of the printed running paper 1 with respect to the transfer rollers 14 and 15 are small, and Transfer to folding machine B system is performed smoothly. Further, the above-mentioned operation is performed in the same manner when the printed running paper 1 is transferred from the folding machine B system to the folding machine A system. Note that the phase alignment of the printed paper, which was performed by the movable transfer roller 015 of the conventional printed running paper transfer device for the folding machine shown in FIG. good.

の折機用印刷済走行紙転送装置。1 Printing for a folding machine of a rotary printing press in which printed running paper, which has been folded along the running direction to form a fold on one side edge, is transferred from one folding machine system to the other folding machine system via a transfer roller. In the printed running paper transfer device, a small diameter portion of one roller is formed at one end in the axial direction of the transfer roller to contact the edge folded portion of one thick side of the printed running paper. 1 which contacts the other side edge where the paper thickness is thinner than the folded part
forming two roller large-diameter portions on the other axial end side of the transfer roller, and making the radius of the roller small-diameter portion including the folded portion substantially equal to the radius of the roller large-diameter portion including the other side edge; A printed running paper transfer device for a folding machine of a rotary printing press, characterized in that the transfer roller is disposed upstream of a folding cylinder so that the wrapping angle of the printed running paper around the transfer roller is small.
