ABSTRACT:
A device for welding plastic foil strips together with a heating device and a pair of pressure rolls between which the strips are fed, includes a pressure device supported by a spring mechanism for one of two pressure rolls. The pressure device includes a first regulating mechanism for the setting of the width of the gap between the two pressure rolls and a second regulating mechanism for the setting of the welding pressure which is arranged on the first regulating mechanism and which can be moved by it. The regulating units of the two regulating mechanisms are two interacting eccentric elements. This leads to a compact design and only little force is necessary for the setting of the welding pressure.
