FILM AND PACKAGE HANDLING APPARATUS FOR WRAPPING MACHINE Abstract of the Disclosure In a stretch film wrapping machine improved film feeding apparatus facilitates the threading of stretch film into film feeding jaws. Sealing/ conveying apparatus is closely located above the film feeding jaws and is mounted to be pivotally moved in line with the machine away from the film feeding jaws. A package sealing holddown is positioned over the sealing/conveying apparatus to ensure firm contact between wrapped packages and the sealing/conveying apparatus. The sealing holddown is pivotally mounted to similarly move away from the film feeding jaws in line with the film wrapping machine. Inexpensive latching means are incor- porated into the sealing holddown and the package sealing conveyor to maintain them in an elevated position to provide free access to the film feeding jaws. The package holddown comprises a roller with a central section of a first diameter and two outer sections of a second larger diameter which are connected to the central section by frustum sections. The holddown roller is driven by belts to complement the conveyor action of the sealing/ conveying apparatus.
