Abstract

The present invention provides a control apparatus and a control method for a barred body printer, capable of automatically regulating the position of a folding triangular plate or a turning bar in the conveying direction of the barred body, or the position (horizontal) of a chopper in the direction being vertical with the conveying direction of a book card. A web press as the barred body printer is provided with a detector (29), located downstream of the folding triangular plate (108) and provided halfway through a transport path for a web (Wb) or a signature (Sb1) from the folding triangular plate (108) to the chopper (107b), for detecting the position of an end portion of the web (Wb) on a side folded by the folding triangular plate (108); and a folding triangular plate and turn bar control device (10) for adjusting the position, in the paper flow direction, of the folding triangular plate (108) or the position, in the lateral direction, of the chopper (107b) in response to an output from the detector (29).

Description

technical field [0001] The present invention relates to a control device and a control method for a web printing machine such as a web rotary printing machine. Background technique [0002] In the offset rotary printing machine, due to changes in the state of the printing machine such as the rotation speed of the printing machine, the blowing amount of the former or the steering rod changes, and the degree of bulging of the web changes. When the state of the folding machine changes, the position of the signature delivered to the guillotine folding part of the folding machine changes. [0003] Therefore, in the past, whenever the state of the printing machine changed, the operator had to manually adjust the position of the folding former or the steering rod along the paper conveying direction or the left and right position (horizontal direction) of the knife.
