Abstract (en)
[origin: EP0447375A1] The device is associated with a line consisting of at least two equal chains (80,81), winding themselves round in a closed ring, according to horizontal planes, motorized with equal speeds, provided with radial prongs (17b,17a), oriented outwards, individuating a series of vertical seatings (45), and of a magazine (6) containing a pile (P) of blanks (1) of flattened tubular form. First means (7) provide for taking the lower blank (1a) of said pile and for positioning it, horizontally, in an intermediate station (I) where second means (16), acting in relationship of phase with the former, catch said blank, which is imparted a spatial motion of progressive orientation of its axis from horizontal to vertical, and of rotation with respect to the same axis in order to intercept a fixed catch projection (60) first, with partial opening of the same blank, and then the prongs (17a,17b) of a corresponding vertical seating (45) with a speed component (H) contrary to the direction of translation of the prongs themselves, with the completion, through these latter, of the opening of the blank. <IMAGE>
