Abstract: A cyclical extraction of an empty and closed box from a feeding magazine is performed by an extractor and an opposite contrast device which transfer the box into an opening station. The contrast device rotates of 90°, opening the box and entering it. While the contrast device goes back, the extractor places the box open on underlying double-slope inclined planes, on which the box is finally placed by arc-shaped and oscillating levers. While the contrast device goes back, the open box is transferred to an adjacent parking station which includes an upper contrast device to maintain the box on the support guides. A finger completely opens downwards an external pocket of the transferred box, and a known device introduces into the pocket a customizing insert sheet. The open box then leaves the parking station and reaches is transferred to filling and closing stages.

Abstract: The present invention provides for the cyclical extraction of an empty and closed box (C) from a feeding magazine (1) by means of an extractor (8) and of an opposite contrast means (18) transferring said box into an opening station, where said contrast means rotates of 90° on its horizontal support stem (19), opening the box and entering it. While the contrast means (18) goes back and in due time the extractor returns to the magazine to repeat another work cycle, said extractor places the box open on underlying double-slope inclined planes (36, 36′), on which said box is finally placed by arc-shaped and oscillating levers (39, 39′), which are then deactivated and on which it is kept by springy teeth (38, 38′).
