Abstract
A transverse sealing device in a tubular bag forming machine that has two sealing jaws with flat sealing faces disposed in an interstice between two pairs of clamping jaws, and also has a severing knife for longitudinally dividing the crosswise seam made by the sealing jaws. In order to remove the severing knife from the thermal influence of the sealing jaws, the severing knife is disposed and is movable separately from the sealing jaws and in a position of repose is located outside the range of motion of the sealing jaws. To that end, an aperture is provided in one of the clamping jaws for receiving the severing knife in the position of repose, and an arm supports the severing knife and also protrudes through the aperture.
