Referring to FIG. 5, a folding machine 01 includes a folding cylinder 02 and a cutting cylinder 03 which rotate in the directions indicated by arrows. , And a holding cylinder 04, and the printed web 05 supplied from a printing unit (not shown) to the folding machine 01 is sent between the folding cylinder 02 and the cutting cylinder 03.

[0004] The web 05 is attached to both trunks 02, 03.
Is cut to a predetermined size and wound around the folding cylinder 02 by a needle (not shown). .

[0005] The web 05 folded in this way is transported by being sandwiched between the paper ejection belts 06 and 06 stretched up and down, discharged by the impeller 07 onto the paper ejection conveyor 08 and transported to a predetermined position. Is done. As a result, a two-fold (parallel fold) signature indicated by reference numeral 09 is obtained.

A chopper 010 having a chopper blade which moves up and down is provided in the signature transfer path by the paper discharge belts 06 and 06, and a blade having the same structure as the impeller 07 is provided below the chopper 010. A wheel 011 is mounted on an impeller 07 so that the axis is orthogonal to the axis.

If one wishes to obtain a four-fold (chopper-folded) signature as indicated by reference numeral 012, the chopper 01
In operation 0, the signature 09 being transported by the discharge belts 06 and 06 is folded from the center by the chopper 010, and is discharged onto the discharge conveyor 08 by the impeller 011 and transported.

[0008] As described above, two types of signatures 0 can be created by one folding machine.
