Abstract
A decoration correction method for a form-and-seal unit for producing sealed packages of a pourable food product from a tube of packaging material fed along a feed path, and having two pairs of jaws movable along the feed path and opened and closed so as to travel, cyclically and alternately with each other, along a form-and-seal portion along which the pairs of jaws are closed and travel integrally with the tube, and along a repositioning portion along which the pairs of jaws open and move with respect to the tube. To make a decoration correction, a nominal trajectory of the jaws is modified along the repositioning portion on the basis of a position error of the tube with respect to a nominal position. A first solution provides for correcting the travel of the jaws by selectively modifying the amplitude of the trajectory; and a second solution provides for correcting the phase of the jaw trajectory.
