Abstract

L'invenzione concerne un procedimento per separare e un dispositivo per tagliare a misura tubi laminati a freddo a passo di pellegrino, sollecitabili su una torsione elastica, durante la laminazione su un impianto di laminazione a freddo a passo di pellegrino con gabbia di laminazione alternativamente mossa come pure con avanzamento ad intermittenza e/o rotazione a intermittenza del tubo nella zona di uno di entrambi i punti morti della gabbia di laminazione. Per permettere un taglio a misura i tubi laminati a freddo a passo di pellegrino durante la laminazione, senza problemi senza taglio a misura successivo della estremità del tubo, secondo l'invenzione viene proposto che in una zona a distanza determinata in dipendenza del materiale e della dimensione, posteriormente alla zona di laminazione al tubo viene imposta, nella zona a distanza, una rotazione costante corrispondente alla velocità di rotazione media del tubo, contemporaneamente ruotante elasticamente questo, durante la quale ha luogo la separazione del tubo in questa zona a distanza.Il dispositivo per l'attuazione del procedimento è caratterizzato dal fatto che il dispositivo separatore è previsto a una distanza (a) atta a permettere la torsione elastica del tubo (4) e presenta una bussola di serraggio (10) azionata a ruotare costantemente, circondante in modo serrante il perimetro del tubo.
