Mandrel for holding and aligning film supply rolls

Abstract:

A mandrel includes a shaft that can hold a supply roll of film. A primary button and one or more secondary buttons are located on the shaft. The primary button and the one or more secondary buttons are biased toward an extended position and are capable of moving to a retracted position. The primary button and the one or more secondary buttons retract to the retracted position during at least a portion of loading the supply roll of film onto the shaft. The retraction of the primary button to the retracted position causes retraction of the one or more secondary buttons to the retracted position. When the supply roll of film is in an aligned position on the shaft, the supply roll of film is maintained in the aligned position in part by one of the primary button and the one or more secondary buttons in the extended position.
