ABSTRACT:
A cartoning machine which folds a carton blank into a carton having a box body and a box lid which are connected together during a single rotation of an intermittently rotating rotary body. The rotary body is provided with a plurality of pairs of positive dies, each pair of positive dies having dies respectively corresponding to the box body portion and the box lid portion. Disposed at certain angular intervals around the rotary body are a magazine for supplying carton blanks, a box body folding device having a box body negative die, a box lid folding device having a box lid negative die, and an ejecting section for discharging completed cartons. Cartons are continuously formed by the intermittent rotation of the rotary body and the relative movement between the above two box folding devices and the pairs of positive dies, the dies in each pair being movable back and forth separately.
