を減少させることができる。 As is clear from the above explanation, according to the present invention, in the plate vise device of a sheet-fed rotary printing press, a pair of washers are interposed between the head of the bolt that supports the presser plate on the vise stand and the presser plate. The opposing circular arc surfaces of these washers are used as sliding surfaces for rotating the presser plate, and the center of this circular arc surface is set on the same plane as the plate gripping surface formed by the presser plate and vise table. By doing so, when the presser plate is rotated to grip the plate, the plate does not move from the time the presser plate touches the plate from the right angle until it finishes gripping the plate, so the plate can be held accurately. The ability to hold the plate in your mouth ensures the registration accuracy of the plate and improves the quality of printed matter.It also reduces the time required for registering the plate, reducing preparation time and improving the operating rate of the printing press. The amount of waste paper generated can be reduced.
