A seaming assembly for seaming a can lid onto a can body, the seaming assembly comprising:
- a chuck;
- and
- a knockout pad that is movable relative to said chuck in an axial direction of said chuck, the knockout pad includes:
- a fastening element, and
- a holding element configured and arranged in a spring-loaded manner relative to the fastening element, thereby forming a spring-loaded assembly such that contact with said can lid is effected and established in a spring-loaded region,
- at least one spring positioned above said holding element and around said fastening element, and
- a knockout rod, wherein said knockout pad is secured on the knockout rod, and the knockout rod is configured and arranged to be moved together with said knockout pad in the axial direction of said chuck.
A method for seaming a can lid onto a can body, the method comprising the steps of:
- supplying said can lid and said can body to a seaming assembly of a warner;
- positioning said can lid on said can body;
- positioning said can body on a lifting element;
- exerting a spring load upon said can lid by way of a spring-loaded holding element and a fastening element of a knockout pad that is movable relative to a chuck in an axial direction of said chuck, wherein the holding element is configured and arranged in a spring-loaded manner relative to the fastening element such that the contact with the can lid is effected and established in a spring-loaded region, wherein said knockout pad is secured on a knockout rod, and said knockout rod can be moved together with said knockout pad in the axial direction relative to said chuck, and wherein at least one spring is positioned above said holding element and around said fastening element;
- seaming said can lid to said can body by way of at least one seaming roller and said chuck;
- synchronously lowering said knockout pad and said lifting element while maintaining the spring load upon said can lid;
- raising said knockout pad from said can lid;
- and
- discharging said seamed can from said seamer.
