A device for opening out blanks supplied in a flattened tubular configuration, comprising: a store (100) for containing a stack (P) of tubular blanks in a flattened configuration; first means (200) for hooking a first flap (1A) of the two external flaps (1A, 1B) of the base blank of the stack; a drum (300) set in constant rotation, peripherally exhibiting angularly-equidistanced work stations (20), each of which comprises retaining means (22) destined to receive, from the first hooking means (200), the first flap (1A) of a blank (1), such as to position the score (2A), connecting the two external flaps (1A, 1B) along an axis C parallel to the rotation axis (11) of the drum, and comprises folding means (29) made to oscillate in a direction (R) which is opposite the rotation direction (F) of the drum, about the axis (C) such as to intercept the second flap (1B) of the two external flaps.
