CARTON FORMING MACHINE AND METHOD ABSTRACT OF THE DISCLOSURE A forming machine which permits a preformed corru- gated board blank to be manually fed into one end of the machine, which blank has the rear flaps manually folded over and held until they are engaged by hold-down de- vices on the machine. The blank is moved through the machine by a drive belt and is sequentially acted upon by a folding structure which folds over the front cor- ner tabs. A glueing device applies adhesive to the side flaps, and a further folding structure then folds over the side flaps for adhesive securement to the previously- folded corner flaps. The folding structure for the front corner tabs is nonpowered and includes levers for lifting the front tabs in response to movement of the tabs into engagement therewith, following which the front tabs are appropriately folded over while the side flaps pass beneath the lifting levers.
