Abstract

La macchina dentatrice è del tipo costituita da una coppia di teste (2, 3) coassiali di supporto bilaterale e di movimentazione di un creatore (4) assialmente cavo, una (2) delle quali é mobile da e verso l'altra ed una è provvista di primi mezzi di fasatura (16) cooperanti con corrispondenti secondi mezzi di fasatura (6) associati al creatore (4), e prevede che il creatore (4) sia provvisto direttamente dei rispettivi mezzi di fasatura (6), prevede che a ciascuna delle teste (2, 3) sia associabile un rispettivo perno di centraggio (7, 8) assialmente cavo, dotato di un collarino di riscontro (17, 18) ed alloggiabile complementarmente nel foro assiale (5) del creatore (4) fino a battuta contro di esso tramite i rispettivi collarini (17, 18), e prevede che una delle teste (2 e 3) sia provvista di un tirante (9) ad essa coassiale e che l'altra (3 o 2) sia provvista di mezzi (11) di trattenimento e di trazione del tirante (9) introdotto all'interno del creatore (4). (Fig. 1).
