Abstract
Una molteplicità di stampi dentati viene formata sulla rispettiva superficie periferica esterna del primo e secondo rullo (14, 15) per sagomare un materiale di aletta, ciascuno degli stampi dentati avendo coste che si estendono parallelamente ai rispettivi assi dei rulli. Ciascun stampo dentato include una molteplicità di serie di lame di sagomatura, ciascuna includente una cavità di sagomatura (24a, 14b) una parte piana (26a, 26b) che è contigua alla cavità di sagomatura ed una sporgenza di sagomatura (25a, 25b) contigua alla parte piana, che si estende ad angoli retti rispetto alla direzione di sviluppo delle coste e sistemata lungo le coste. In questo caso, un materiale di aletta viene sagomato in maniera tale che le cavità di sagomatura (24a) del primo rullo stanno singolarmente di fronte alle sporgenze di sagomatura (25b) del secondo rullo, in maniera tale che le sporgenze di sagomatura (25a) del primo rullo stanno singolarmente di fronte alle cavità di sagomatura (24b) del secondo rullo, e vengono formate disposizioni a persiana per taglio. Scanalature di uscita (41a, 41b) sono formate sulle rispettive superfici opposte delle sporgenze di sagomatura (25a, 25b) su cui i rispettivi stampi dentati del primo e secondo rullo sono contigui per impegno dell'uno sull'altro.
