Packaging material folding device of packaging machine

Abstract

A wrapper folding apparatus of a packaging machine has a second wheel () for use as a folding turret. The second wheel () is supplied with a cigarette bundle and an aluminized sheet (S) in an inlet position. As this is done, the aluminized sheet (S) is folded around the periphery of the cigarette bundle, and lug portions formed by the peripheral folding are folded by the use of primary lug folding guides (). Since the lug protions are kept folded by the use of holding guides () thereafter, they cannot be freed until an outlet position is reached. When the cigarette bundle is discharged in the outlet position of the second wheel (), the lug portions on the end-flap side are folded by the use of secondary lug folding guides (). After the folding, side flaps continue to be folded without allowing the lug portions to be free.
