Zusammenfassung:The disclosure relates to relates to the use of trim sensors, registration sensors or pressure sensors to sense the position of a zipper during the manufacture of reclosable packages, particularly manufacturing processes wherein the ends of the zipper need to line up at the fin seal to insure success of the closure. The output of the sensors is used to adjust belt or roller speeds, or similar operational parameters to bring the zipper profiles into alignment at the fin seal.
