き込むように機能するものである。As described above, in the conventional general lateral needle device, lateral needle devices composed of an upper roller and a lower roller are installed at both ends in the sheet width direction. The roller is a floating roller that is attached to the elevating shaft, and it descends at a predetermined timing after passing the sheet, and functions to pinch the sheet between the lower roller that is forcibly driven to rotate and pull the sheet toward the lateral width edge of the sheet. To do.

発生要因となっていた。Therefore, since the lateral needle devices at both ends of the sheet pull the sheets in mutually opposite directions, it is impossible to operate them at the same time. The side which becomes a reference in regulating the position of the sheet, that is, the operating side or the driving side. A method was adopted in which only one of the two sides was activated and the other side was kept in a standby state with the upper roller raised. For this reason, when the sheet is transferred for printing on thick paper or metal plate, the pulling force is weak against the weight, so it is not possible to reliably move and correct to the side contact plate, which is a cause of printing misalignment. Was becoming.
