When the first air cylinder 27 is extended, the transfer drum 21 rotates counterclockwise around the fulcrum of the bracket 28 to allow the transfer drum 21 to enter the inside of the cutting device 1 to be ready for the next production.

The clockwise rotation is that the transfer drum 21 rotates about the fulcrum of the bracket 28 to the downstream side, and the counterclockwise rotation is that the transfer drum 21 rotates about the fulcrum of the bracket 28 to the upstream side.

Referring to the state iv in fig. 7 and also to fig. 2 and 3, the folding conveyor 3 comprises: a vacuum box 31, a first plate 32, a folding plate 33, a driving roller 34, two driven rollers 35, a second air duct 37 and a second conveyor belt 36.
