Abstract
A packaging machine includes a fixed structure. A number of forming assemblies are arranged successively along a vertical portion of a path of a strip of packaging material, for gradually superimposing opposite lateral portions of the strip to form a tube having a longitudinal axis. A sealing device seals the lateral portions to each other and forms a longitudinal seam of the tube. An actuating device is operatively connected to an angularly adjustable folding member of one of the forming assemblies, and activated selectively to rotate the folding member about the longitudinal axis. A sensor is disposed along the vertical portion of the path, downstream from the sealing device, and generates a position signal correlated to the angular position of the seam. A control unit receives the position signal and generates a control signal, which is supplied to the actuating device to restore the seam to the desired angular position.
