An apparatus for use in a form, fill, and seal packaging machine using preprinted web. The punch apparatus includes a registration sensor, a controller, a punch mechanism, a secondary servo feed drive and a dancer system. The registration sensor reads a registration mark on the web to send a signal to the controller which stops the secondary servo feed drive in a position one panel pitch downstream from the registration sensor. The punch is activated to punch holes along a cut line. The secondary feed drive is activated to advance the punched web to a dancer system. The web is moved from the dancer system to a conventional pouch forming machine by a primary feed drive.

[ What is claimed is:] [1.]1. An apparatus for forming a plurality of flexible pouches from a web having a plurality of spaced apart registration marks, each pouch having a predetermined panel length of one pitch, said apparatus for use with a machine having a primary feed drive and a cutting station, said apparatus comprising:a controller;a punch mechanism for punching holes in said web, said punch mechanism receiving a signal from said controller;a registration mark sensor adapted to read one of said plurality of registration marks and send a signal to said controller, said sensor spaced a distance of one pitch upstream from said punch mechanism;a positioning mechanism for selectively positioning said punch mechanism to and away from said sensor; anda secondary feed drive positioned upstream of said primary feed drive, said controller stopping said secondary feed drive when said sensor detects a registration mark.
