Abstract
A system for controlling registration on a pouch knife machine of a longitudinally extending bandolier of content containing pouches separated by transverse seal seams moving along a feed path, with each pouch having a measurement reference. The machine includes a knife mechanism, a friction drag mechanism, and a friction drag adjustment mechanism. The system includes an optical reference, an optical image sensor, and a controller. The controller is configured to determine an actual position of the measurement reference relative to an optical reference, determine an alignment input based upon the actual position of the measurement reference relative to the optical reference, determine an alignment difference between a target position and the alignment input, and generate an adjustment command to change the position of the bandolier along the feed path after the alignment difference exceeds the operating range for the target position.
