ABSTRACT:
A transfer assembly to progressively transfer to a main vertical magazine located at the top of a machine for forming cardboard boxes, the cardboard box at the top of the pile of cardboard boxes located in an auxiliary magazine to one side of the forming machine. There is associated with the transfer assembly, opposite the top of auxiliary magazine, a solenoid valve through which the upward movement of the cardboard boxes in axiliary magazine is stopped in the time interval between the start of the withdrawal of the cardboard box from the auxiliary magazine and its positioning on rollers. At the top of the main magazine there is an upper photocell suitable for stopping the movement of the transfer assembly when the main magazine is full and a lower photocell suitable for putting the same assembly back in motion when the number of cardboard boxes contained in main magazine is lower than a certain threshold.
