First Claim
Patent Images
1. A package wrapping machine for handling trayed items, each trayed item including product within a tray that has a tray lip, the machine comprising:
- an infeed station at which trayed items to be wrapped are placed;
a conveying system for moving trayed items into the machine and to a wrapping station where film is manipulated to wrap trayed items;
a sensor arrangement for detecting trayed items moved by the conveying system;
a controller associated with the sensor arrangement and operable to identify tray lip height for trayed items based upon outputs from the sensor arrangement, the controller setting one or more wrap parameters based upon identified tray lip height.

Abstract
A package wrapping machine includes a wrapping station where film is to be manipulated during a packaging operation. A support is provided for holding rolled film, the support located to permit film to be drawn into the wrapping station. A sensor arrangement detects package size data that is used to set one or more wrap parameters.
