<p>A station S includes a deep magazine (10) containing, on superimposed planes, stacks (P1, P2, P3) of flat folded tubular blanks (1), arranged horizontal. Each stack (P1, P2, P3) is supported at the base by corresponding openable support means (11, 12, 13). A platform (10), moving vertically, is situated below the deep magazine (30) and receives, when set at a raised loading position (C), one stack (P) released by the first openable support means (P1), with the platform (11) subsequently lowered, together with the stack (P), to a waiting position (A). The station (S) includes also withdrawing means (40), moving horizontally between two extreme positions (R, T), in the first of which they are above the stack (P), supported by the platform (30), and, in step relation with a calibrated raising of the platform, followed by a new lowering to the waiting position (A), they pick up the topmost blank (30) of the stack (P), whereas in the second position (T), they are outside the platform (30), to deliver the topmost blank (1s) to box forming means of the boxing machine (M). When the stack on the platform (30) is used up, the magazine (10) releases another one, while the stacks remaining in the magazine fall down in a sequence to a lower level, so that the bottommost place is always occupied.
