ABSTRACT:
The invention relates to a process and apparatus for truncating tubes by means of a knife activated by a jack. The knife is mounted on a knife carrier pivotable on a base by one of the ends of a jack the other end of which is journalled on a lever similarly pivotable on the base and which rests in part on an elastic abutment adapted to pivot the lever towards the tube to be cut after having been compressed by the lever during a pivoting of the lever in a direction opposite to the tube and after an interruption of the extension of the jack, with a stop being provided to limit the extent of pivoting of the lever in the direction opposite of the tube to be cut.
