A machine for grouping packs includes a sliding work plane for advancing in sequence at least a consecutive and equidistanced row of packs along a predetermined advancing direction (A); and a retaining means for cyclically braking the advancing of one of the packs of the row with respect to the sliding work plane, the retaining means including at least a striker body and a moving means for cyclically locating the striker body close to a pack advancing on the work plane, such that the striker body receives the pack in contact there-with, preventing the pack from advancing at a same speed as a previous speed thereof on the work plane.
