ABSTRACT:
A method of making and filling reclosable packages using a duplex machine includes the steps of providing a zipper profile, package film and a plurality of sliders; feeding the zipper profile; applying the sliders to the zipper profile; coupling the zipper profile to the folded web; sealing two edges of the folded web to form adjacent pouches; filling the pouches; sealing the pouches proximate a third edge thereof; and separating the pouches in order to form individual packages. The method employs a single rotating slider applicator having a programmable servo motor which is programmed in order to synchronize the application of the sliders to the moving zipper profile with the two at a time form, fill, seal and separate packaging operations of the duplex machine. A duplex machine is also disclosed.
