に支障が生ずることがあった。2. Description of the Related Art Heretofore, when a web is turned over to perform double-sided printing in an offset rotary press or the like or when slit webs are overlapped with each other, a traveling bar is passed over a traveling web to change the traveling direction of the web. For example, if two turn bars are passed diagonally, the web can be inverted. The turn bar can be used as long as it is a cylindrical rod, but if the surface in contact with the turn bar is printed, the print surface is rubbed because the turn bar and the print surface are rubbed. For this reason, in such a case, a drill hole is made in some places of the hollow cylinder, and compressed air is blown into the hollow cylinder to blow out from the drill hole, so that the web is brought into a non-contact state. Further, a turn bar whose surface is covered with Teflon tape is also used. However, with the increase in printing speed, the conventional method is insufficient and often causes stains due to rubbing with the turn bar. Further, the water content of the web has been reduced by the printing drying process, and the web has come into contact with the web to generate static electricity, which may hinder the processing of the web in a subsequent process.

である。According to a first aspect of the present invention, there is provided a method of changing a traveling direction of a web by passing a turn bar obliquely to a traveling web, wherein the turn bar has a large number of fine holes. A method of converting a traveling web which is a sintered metal and blows out humidified air from the fine holes. The invention according to claim 2 passes a turn bar obliquely to the traveling web to advance the web. In the method for changing the direction, the turn bar is a sintered metal having a large number of fine holes, and the ionized air is blown out from the fine holes.

い。Hereinafter, the present invention will be described with reference to the drawings. The turn bar 10 used in the present invention has a diameter of 10 to 10 on the surface.
It has a cylindrical shape in which 30 μm fine holes are distributed on one surface. Air is supplied to the hollow portion 11 and blows out from the fine hole. The turn bar can be manufactured by sintering several layers of metal wire mesh having a fine mesh, or by sintering powder metal by pressing and heating.
Stainless steel, copper, etc. can be used as the metal material. In the method of the present invention, air is supplied to the hollow portion 11 of the turn bar from an air supply source 12 such as a compressor or a blower by piping. The supplied air is humidified. The method of humidifying the air can be achieved by providing the humidifier 13 in the pipe from the air supply source to the turn bar or in the hollow portion 11. In the present invention, the air is supplied after being ionized. In this case, an air ionizer for generating high frequency in the air and ionizing the air may be provided instead of the humidifier.

という効果を有する。According to the present invention, since a turn bar of a metal sintered body having a large number of fine holes is used, an air film is formed on the surface of the turn bar, so that the web hardly comes into contact with the turn bar. The direction of travel of the web can be changed. For this reason, no extra tension is applied to the web and no wrinkles are generated on the web. Furthermore, since humidified air or ionized air is supplied, there is an effect that static electricity on the web is removed.
