A station includes a magazine containing stacks of flat folded tubular blanks arranged horizontal. Each stack is supported by openable support pad pairs. A platform moves vertically below the magazine and receives, when set at a raised loading position, one stack released by opening a lowermost pad pair. The platform is subsequently lowered, together with the stack, to a waiting position. A withdrawing arm, mounted on a slide moving horizontally, has suction cups for picking up a blank from the stack on the platform, when the platform is temporarily raised and then lowered to the waiting position. After picking up a blank from the stack, the slide and arm take the blank to box forming means of the boxing machine. When the stack on the platform runs out, the magazine releases another stack, while the stacks remaining in the magazine fall down in a sequence to lower levels, due to opening of the pad pairs.
