Abstract

A film dispenser for a stretch wrapping apparatus is provided. The film dispenser includes a pre-stretch assembly having a top portion mounted to and extending downwardly from a drive plate of a roll carriage frame. The pre-stretch assembly includes two pre-stretch rollers having first ends connected to the roll carriage frame and second ends connected to one another. The pre-stretch rollers may be coated. The pre-stretch assembly further includes a cantilevered idle roller mounted to the drive plate and positioned between the pre-stretch rollers. A film path is defined by the space between the pre-stretch rollers and the idle roller. The film path is easily accessible via the bottom end of the pre-stretch assembly.
