The disclosure relates to a wrapping material system in a harvester, particularly to a latching mechanism that allows a material support cylinder to be unlocked and automatically ejected from its locked position. The latching mechanism comprises a support plate, connected to a harvester sidewall and configured for supporting the material support cylinder, and a lever plate, connected to the support plate at a pivot point and configured for locking in the material support cylinder in a closed position and ejecting the material support cylinder from the locked position when moved to an open position.
