Abstract

Per una sega a spada (1) azionata meccanicamente che reca, senza che possono andare perse, due lame di sega (7, 8) disposte reciprocamente parallele, mobili con moto alternativo in senso opposto con una corsa, con una punta anteriore (27, 28) della lama di sega ed un'estremità di serraggio (39, 40) opposta, accoppiate tramite mezzi di serraggio (57, 58) ad un azionamento e recanti su un lato dentato (29, 30) denti di sega (31, 32), condotte una accanto all'altra con il loro dorso (24, 25) della lama di sega opposto al lato dentato (24, 25) in una scanalatura di guida (23) nella regione inferiore della spada (6) a forma di piastra, vengono realizzati un serraggio ed un'asportazione rapida delle lame di sega mediante il fatto che le lame di sega (7, 8), in particolare insieme, sono accoppiabili con i mezzi di serraggio (57, 58) o asportabili da essi senza un utensile ausiliario, mediante il fatto che mezzi di blocco (63) disposti al di fuori dei mezzi di serraggio (57, 58) o al di fuori delle lame di sega (7, 8), in particolare solidali con la carcassa, bloccano e sbloccano senza contatto le estremità di serraggio (39, 40) nella posizione di accoppiamento.(Figura 1).
