A method and a relative unit ( 1 ) for producing blister packs ( 7 ) by cutting a blister band ( 4 ), according to which a band ( 4 ) with blisters ( 2 ) housing products is fed in a selected feeding direction (A), through subsequent stations: a band ( 4 ) verifying station, a closing station where the blister band is closed with a covering band, and to a cutting station ( 5 ) for cutting the closed blister band ( 4 ). In the cutting station ( 5 ), the closed blister band ( 4 ) is cut by progressive shearing, to obtain relative blister packs ( 7 ) detached from at least one strip ( 9 a, 9 b) or scrap longitudinal edge of the blister band ( 4 ). If portions of the blister band ( 4 ) considered unsatisfactory are detected in the control station, the subsequent shearing is performed partially or incompletely, so as to prevent detachment of the corresponding blister packs ( 8 ), considered faulty and destined to be rejected, from the strip ( 9 a, 9 b) of the band ( 4 ). |
