ABSTRACT:
Loads on pallets are often wrapped with a plastic film for shipping. The present invention relates to top platen devices used to maintain stability in loads while the load is wrapped for shipping. The top platen device applies a compressive force to the load to stabilize the load while it is being wrapped. The top platen includes a shaft supporting platen pad which is placed on top of the load. The shaft and platen pad are configured to rotate eccentrically with respect to the geometric center of the top platen in order to rotate with the load about the load's center of rotation.
