Downstream of the welding and cutting bars (14, 16), a crosspiece (18) interacts with two pressure elements (20, 34) which act alternately in order to retain the manufactured articles on said crosspiece, engaging in each cycle the new manufactured article to be accumulated; downstream of said welding bars and said crosspiece, a transporter element (60A), endowed with a movement which corresponds to that of the manufactured article under formation, moves with an active trajectory above the stack under formation (PO) and assists it to extend above the stack under formation; said transporter element (60A) removes itself from below said manufactured article when the latter is engaged by the first pressure element (20). <IMAGE> |
