A crimping unit (1) having a first plate (10); a first lever (50) equipped with a winding wheel (54), a second lever (60) equipped with a crushing wheel (64), a winding actuator connected to the first lever (50), and a crushing actuator connected to the second lever (60). The winding actuator and the crushing actuator are governed by an electronic control unit (7) to vary the distance between the winding wheel (54) and/or the crushing wheel (65) of the first axis according to the angular position of the first plate (10) around the first axis.

A seaming roll for sealing a container includes a rotation body rotatable on a bolt for sealing the container. The rotation body includes a first basic side and a second basic side different from the first basic side and a bearing. The bolt is arranged on the bearing via the first basic side such that the rotation body can be rotated about the bolt in the circumferential direction of the second basic side when the container is sealed. The seaming roll further includes an exchangeable seaming profile for seaming a container lid with a body of the container and a fastening mechanism. The exchangeable seaming profile is detachably connected to the rotation body via the fastening mechanism.

The present application is directed to a double seam modification tooling apparatus for double seam modification and the double seam modification process. More particularly, a tooling apparatus for double seam modification is provided which adds a third modification operation to the first and second double seam operations which form the finished double seam, as well as a process for modifying double seams to include patterns of integral slots, notches or threads, or the like, after the double seams have been previously completely formed by the double seam modification tooling apparatus. Child resistant lids can then be configured with mating tab notches or tab threads to allow for opening or closing the lid when the tabs are properly aligned with the notches and threads on the can rim modified double seams.

A can seaming apparatus including a frame, a can handling assembly, a can driving assembly and a seaming assembly. The can seaming apparatus is configured to seal a lid to a can through a double seam can seal. The can is positioned and clamped between an upper and a lower chuck. The can driving assembly spins the can and the upper and lower chucks about an axis. The seaming assembly includes two rollers which can selectively be directed to engage the can to form the necessary crimping operations.
