A device for opening out blanks supplied in a flattened tubular configuration comprises a store (100) for containing a stack (P) of flattened tubular blanks, a first hooking device (200) for hooking a first flap (1A) of two external flaps (1A, 1B) of a base blank of the stack, and a drum (300) set in constant rotation, peripherally exhibiting angularly-equidistanced work stations (20). Each work station has a retaining apparatus (22) for receiving, from the first hooking device (200), the first external flap (1A), so as to position a score line (2A), connecting the two external flaps (1A, 1B) along an axis C parallel to the rotation axis (11) of the drum. A folding device (29) oscillates in a direction (R) which is opposite the rotation direction (F) of the drum, about the axis (C) so as to intercept the second external flap (1B). |
