ABSTRACT:
A process and arrangement for controlling a pipe-cutting device for cutting pipe formed on a continuously operating spiral winding machine which forms a pipe from a band of wound sheet material such as paper. The pipe-cutting device is adapted to move along the formed pipe at a speed corresponding to the feeding speed of the band which is being guidingly fed at a predetermined feed angle toward the pipe-forming spindle of the spiral winding machine. An arrangement is provided in a continuous spiral pipe-winding machine for controlling the movement of a cutting member. The cutting member is mounted on a sled adapted to reciprocate along the spindle of the pipe-winding machine at an advancing speed which is continuously adjusted in accordance with the advancing speed of the pipe and is of a construction for carrying out the process of this invention, whereby the band of sheet material which is fed to the winding spindle of the machine is guided over a measuring roller which is operatively connected to a pulse emitter. The pulse emitter is operatively connected with a pulse counter of an AND/OR-comparator stage, the outpulses of which release the advance of the cutting member.
