The present invention relates to a testing lid for testing the stroke of a holding plate of a closure head of a can closing device for cans, in particular beverage cans, the testing lid comprising: an edge portion provided for positioning onto a can edge, in particular for additional crimping with the can edge; and an inner portion, in which one or a plurality of testing pins are arranged in a force-fitting manner, the testing pins being displaceable by the holding plate in the direction of stroke while a stroke of the holding plate is taking place. The invention additionally relates to a method of testing the stroke of a holding plate of a closure head of a can closing device for cans making use of the testing lid according to the present invention.

A can end includes a center panel, an annular portion disposed about the center panel, a chuck wall disposed about the annular portion, a curl extending radially outwardly from the chuck wall, the annular portion including an annular ridge and an annular countersink, the annular countersink disposed adjacent and about the annular ridge. The annular countersink and the annular ridge are structured to resist deformation from external or reverse pressure.

The invention relates to a seaming assembly for seaming a can lid onto a can body with a chuck and a knockout pad that is movable relative to the chuck in an axial direction of the chuck, where the knockout pad comprises a holding element arranged in a spring-loaded manner. Furthermore, the invention relates to a method for seaming a can lid onto a can body using the seamer according to the invention.

Provided is a seaming device capable of easily adjusting clearances between a chuck unit (seaming chuck device) and first and second seaming rolls in a short period of time, easily changing a seaming cycle, and producing a seamed sample can at a normal operation speed. In the seaming device, a seaming unit (130) carries out seaming operation by seaming rolls (131), a driving source for the swinging shaft (132) of the seaming rolls (131) is configured to be capable of controlling the seaming operation independently, and the driving output shaft (137) of a driving source (158) and the swinging shaft (132) of the seaming rolls are coupled through a ball spline (140).

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.

A can seamer comprising a frame, a lower chuck, an upper chuck, a first and second seam forming assembly, a seam drive assembly and a motor. The upper chuck having an axle. The seam forming assemblies including a first roller. The seam drive assembly includes a cam, a first roller follower and a second roller follower. A cam transmission assembly includes a drive gear rotatably coupled to the axle, an idler assembly and a cam gear coupled to the cam. The idler assembly includes an idler axle that is spaced apart from the axle. A first idler gear engages the drive gear, and a second idler gear with the first and second idler gears being rotatably coupled to the idler axle. The cam gear engages the second idler gear. The motor has an output shaft rotatably coupled to the axle.
