Abstract

Lama d'acciaio da montare su telai oscillanti per la segagione di materiale lapideo, in particolare telai per il taglio di granito, presentante, in aggetto da almeno una delle sue superfici, una pluralità di nervature parallele, sostanzialmente verticali, di spessore inferiore a 0,50 mm. e con bordi dolcemente raccordati alla superficie della lama. Tali nervature presentano uno spessore compreso tra 0,20 e 0,50 mm. e preferibilmente tra 0,35 e 0,40 mm., una larghezza compresa tra 8 e 30 mm. e preferibilmente tra 10 e 12 mm. ed i loro bordi laterali sono raccordati dolcemente su una ulteriore larghezza di 3 a 15 mm. e preferibilmente di 5 a 6 mm. Il passo tra le nervature è compreso tra 100 e 400 mm. e preferibilmente tra 200 e 240 mm. e le stesse sono formate su entrambe le superfici della lama, in posizioni sfalsate sulle due facce della lama.
