Apparatus for loading carton blanks into a packing machine comprises a magazine (20) containing a stack of flattened, tubular blanks (22), a dog chain (44) driving the blanks out of the magazine into the nip of rollers (52, 54) and then into the nip of overdriven rollers (56, 58) which accelerate the blanks into respective pockets (67) defined in transport holders (30) carried on a wheel conveyor. The blanks are driven at a speed sufficient to carry them into their respective pockets which are moving away from the magazine on the wheel conveyor. A slipping clutch in the drive to roller (56) allows the blanks to decelerate without damage when fully home in their pockets. Arms bearing suction heads travelling with the wheel conveyor open the carton blanks in the pockets and the opened blanks are transferred in their transport holders for bottom closing, filling and top closing operations on respective wheel conveyors. |
