Generally, when high-speed rotary printing is performed using a web (web), the web after printing is cut in a folding machine and then folded laterally to make it suitable for bookbinding. Such horizontal folding of the web is performed by a folding blade protruding in the radial direction from one of a pair of opposing folding cylinders, and forcibly pushing the web into a recess (blade receiver) provided in the other folding cylinder. (Generally called cylinder folding).
In this case, a perforation is placed in advance of the folding drum that performs the cylinder folding, and a perforation is made in advance at the planned horizontal folding position of the web fed to the folding drum, so that the horizontal folding with the folding drum is facilitated. Techniques that improve folding accuracy are commonly employed. In addition, when the web to be supplied is double-folded, perforations may be perforated to remove air from the perforations to prevent fold wrinkles from occurring. In order to form perforations in the web in this way, a perforation cylinder device comprising a combination of the above-mentioned perforation blade cylinder and perforation blade receiving cylinder is incorporated into the folding machine.
しかしながら、このような折胴におけるウエブ

However, in order to facilitate horizontal folding of the web using such a folding cylinder, when perforations are made at the horizontal folding position, the position where the horizontal folding is planned (the position where the folding blade of the plunging cylinder contacts, which will be described later) and If the perforations do not match exactly and accurately, not only is there no point in punching the perforations, but the commercial value of the printed matter decreases, and it may even become harmful.
そこで、従来において、折胴でのウエブの横折

シン刃胴の位相調整を行つた場合と実質的に同じ
結果を得るようにすることが提案されている。 Therefore, conventionally, if the horizontal folding position of the web on the folding cylinder does not match the perforation perforation position, the operation of the rotary printing press is stopped each time, and the horizontal folding position is used as an adjustment reference to adjust the perforation cylinder. Adjustment is made by shifting the phase of the gear so that the perforation position matches the horizontal folding position of the web. Also,
As another means, a correction roller is interposed between the sewing machine blade cylinder (and the sewing machine blade receiving cylinder) and the folding cylinder, and the correction roller slightly presses the web fed to the folding cylinder in the horizontal direction to create a web path. It has been proposed to change this so as to obtain substantially the same result as when adjusting the phase of the sewing machine blade barrel.

位置も狂つてくる等の難点がある。 However, in the former case, it is necessary to stop the operation of the rotary printing press, and in the latter case, not only does the installation space of the folding machine increase due to the addition of the correction roller, but also the web path is changed by the correction roller. There are drawbacks such as changing the cutting position of the web as a result.

がある。 Furthermore, the web cut into sheets is not always horizontally folded at exactly the middle position of the cut length, and for bookbinding reasons, for example, as shown in FIG.
In some cases, the paper is folded horizontally by wrapping the needle hole side at the leading end in the feeding direction by 8 to 12 mm. In this case, the planned horizontal folding position needs to be shifted to a position equal to (1/2 of the cutting length) plus (1/2 of the wrap length) based on the cutting position on the needle hole side. Conventionally,
There was an inconvenience in that the operation of the rotary printing press had to be stopped each time the adjustment was made. Furthermore, when a machine in operation is stopped and then restarted, the tension of the web changes slightly, and the web path from the sewing machine blade cylinder to the folding cylinder caused by the correction roller also shifts. ,
These adjustments require a lot of skill and are complicated.

提供するにある。 Therefore, the purpose of the present invention is to provide a gear as a power transmission mechanism that transmits power from the drive system of the folding cylinder group consisting of the cutting cylinder, plunger cylinder, and biting cylinder to the drive system of the sewing machine blade cylinder and the sewing machine blade receiving cylinder. A simple phasing mechanism is installed in the section, and by operating this phasing mechanism, the sewing machine blade barrel and the sewing machine blade receiving barrel are adjusted and rotated, and the perforations to be drilled in the web are instantly aligned.

の実用的効果はきわめて大きい。 In particular, as is clear from the above configuration, the phasing mechanism of the present invention uses a spur gear instead of a helical gear for the direct barrel gear, and a helical gear between the sewing machine blade barrel and folding barrel. It has a simple structure in which the differential means and the spur gear are integrated, so that it can be used in a small space, has sufficient mechanical rigidity, and improves the meshing accuracy of the helical gear. This makes it possible to assemble easily and to improve assembly accuracy. Furthermore, since the backlash of the gear can be maintained appropriately, transmission of the shock generated when perforating the web to the folding drum can be minimized. Furthermore, if the rotary press is of a different model and has a different diameter ratio between the sewing machine blade barrel and the folding barrel, it can be applied by simply changing the size of the spur gear. It is possible to share the constituent parts, which not only allows for inexpensive manufacturing, but also has the advantage of being able to be manufactured in a short time if necessary. And since the main mechanical parts are attached to the outside of the frame,
Its practical effects are extremely large, such as making maintenance, inspection, and maintenance extremely easy.
