By the way, for example, in a high-speed printing press, several hundred copies are printed per minute. For this reason, even if the operation of the machine is suddenly stopped by a signal from the detecting means, it takes several seconds, for example, for a complete stop due to inertia or the like. However, since the conventional safety device 30 is provided upstream of the flow of the web W in the folding drum portion 48, the operation of the machine is urgently stopped by the paper jam signal from the detection means 30 until the machine is completely stopped. There is a problem that a large amount of signatures 100 are sent from the folding drum portion 48 to the chopper device 55 within a few seconds, and the chopper blade 59 strikes a paper jam. As a result, damage to the chopper blade 59 itself and its drive system, damage to the chopper roller 54, and the like occur. Signature 10 stuck in 56A
Since the operation of extracting 0 is an operation in a narrow place, it takes time and is difficult. As a result, it takes much time to resume operation.

In the above description, the stopper member may be located at any position as long as the stopper member is disposed between the chopper device and the folding drum portion. However, it is preferable that the stopper member be disposed as close to the chopper device as possible. In addition, the stopper member may be of any structure and type as long as it can block the conveyance of the signature. For example, the entire member bridged between the conveyance belts moves up and down, and the lower end surface is lower than the lower part of the signature. , A type in which only a stopper member such as a pin is attached to a member stretched between transport belts so that it can move up and down, and a plate that rises simultaneously with a signal from the table side (lower belt side) of the frame Any type such as the type of member may be used. Furthermore, the stopper member does not need to be arranged at all between the plurality of belt members. For example, a stopper that can stop only at both ends in the width direction of the signature, or a stopper that can stop the central portion,
Anything that can be stopped without turning the signature is acceptable. Further, it is preferable to use an optical sensor or the like as the detecting means.

According to this embodiment, the following effects can be obtained. The stopper member 11 is provided between the chopper device 55 and the folding body portion 48, and when the machine is emergency stopped by the detection signal of the paper jam generated in the chopper device 55, after the emergency stop sent from the folding body portion 48 side. The signature 100 is blocked by the stopper member 11 and is not sent to the chopper device 55. Therefore, since the chopper device 55 has only the number of signatures 100 at the time of paper jam, damage to the machine including the chopper blade 59 and the like can be prevented, and the work for removing the jammed paper becomes easy, and the operation can be resumed in a short time. It becomes possible.

When the stopper member 11 is lowered, its lower end 11B is in contact with the upper surface of the chopper table 56 and is located at a position lower than the lower surface of the signature 100 in the signature conveying belt 50. Can be reliably shut off. Since the escape portion 11A through which the belt member 51 can be inserted is formed below the stopper member 11, the stopper member 1
The belt member 51 is not pressed even at the time of the lowering of 1, so that the belt member 51 is not damaged. Since the stopper member 11 can be moved up and down by the cylinder 13, it is possible to quickly respond to a paper jam detection signal and to reliably shut off the signature 100 to be sent.
