Abstract
Abstract Apparatus for severing a metal band with a chip-removing tool includes drawing off a metal band from a supply reel, feeding the metal band for a given peripheral angle about a support roller in a groove-forming apparatus, cutting in the metal band and lengthwise thereof at least one groove having a depth equal to at least half the thickness thereof with a tool adjustable during the cutting operation in a direction transverse to the direction of feed of the metal band, and finally separating the remaining material at the bottom of the groove along the groove so as to divide the metal band into at least two bands, and apparatus for carrying out the method.
