ABSTRACT:
A welding cylinder, which is mounted in a frame, is provided with welding bars, which can be adjusted continuously in the radial direction, run parallel to the axis of rotation, and are distributed at uniform angular intervals over the circumference. One part of the welding cylinder's circumference is enveloped by a continuous pressure belt, whose loose side travels over guide rolls and rollers of a web storage. Between the guide rollers, bordering the pressure strand of the pressure belt, the web, to be provided with cross welds, runs up onto the welding cylinder and down from it. To adjust in a simple manner the guide rolls of the pressure belt to the different diameters of the welding cylinder, two swivelling and locking levers, whose free ends bear the guide rollers, over which the pressure belt runs up onto the welding cylinder and down from it, are mounted in the machine frame.
