Abstract
A seaming shaft device for a sealer includes a seaming shaft, a seaming device detachable from the seaming shaft, and a fastening mechanism for fastening the seaming device to the seaming shaft. The fastening mechanism includes a lock and a fastener which can be arranged between the lock and the seaming device. The lock and the seaming device can be moved relative to each other along the seaming axis so that the seaming device can be brought from a locked state to an unlocked state, and the fastener in the locked stat is clamped between the seaming device and the lock such that the seaming device is fixed to the seaming shaft. The fastener can be unclamped by bringing the seaming device from the locked state to the unlocked state so that the seaming device is detachable from the seaming shaft.
