VORRICHTUNG ZUM BILDEN VON RINGFÖRMIGEN NUTEN IN DER AUSSENFLÄCHE EINES KABELS ODER ROHRS

摘要

The present invention provides an apparatus (100) for forming circumferential grooves (14) in the exterior surface of a linear member (10), such as a tube. The grooves are formed by rotating a cylindrical cutting element (120) around the tube such that cutting means in the cylindrical cutting element form the grooves. One rotation of the cylindrical cutting element causes multiple grooves to be formed in the surface of the tubes.
