ABSTRACT:
Equipment for continuously feeding a supply of packaging blanks to a packaging machine comprises a feed magazine (10) for holding and sequentially feeding a series of stacks (S1-S5) of packaging blanks, a feed hopper (14) to receive at least one stack of blanks at a time from the feed magazine and present the blanks for use in the machine and a transfer mechanism (12) for transferring a stack of blanks from the feed magazine to the feed hopper. A sensor (66) is provided automatically to actuate the transfer mechanism when the supply of blanks held by the feed hopper reaches a predetermined level and a switch (70) is provided automatically to advance the series of stacks in the feed magazine so that the next succeeding stack is positioned for transfer to the feed hopper.
