The invention relates to a tool for cleaning rollers (2a, 2b) of machines for closing container or cans, which comprises a head (1) which is couplable to a motor and on which are mounted: rotary drive discs (14) of the rollers (2a, 2b) to be cleaned and which comprise at least one element for making contact with the rollers, to transmit traction to same; at least one actuator disc (15, 16) that has a different rotation direction and/or rotation speed to the drive discs (14), and which is provided with at least one element for cleaning the rollers (2a, 2b); and a transmission (50) disposed between the motor and the discs (14, 15, 16).

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.

A tool for seaming and sealing cans such as in the canning of food products. The can seaming tool includes a main pin having a spindle portion and a seam roll connected with the spindle so as to spin about the axis of the spindle. One or more bearing assemblies can be provided between the spindle and the seam roll to facilitate free spinning of the seam roll about the spindle of the main pin. The assembly includes the use of one or more O-rings between the main pin structure and the seam roll. The one or more O-rings advantageously seal the gap between the main pin and seam roll to prevent corrosive materials from the canning environment from entering the assembly and damaging interior components such as the bearing assemblies. This use of sealing O-rings greatly increases the life of the tooling and decreases cost and downtime.
