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.

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.

A crimping structure of a small irregular can and a manufacturing method thereof, in particular to a seam method for buckling a bottom by stamping. The crimping structure includes a can body crimping edge and a can bottom crimping edge made of a plate material of a same type, wherein the can body crimping edge covers the can body crimping edge to crimp 90 degrees inward. A four-layer structure with a first can body crimping edge layer, a can bottom crimping edge layer, a second can body crimping edge layer and a can bottom layer, arranged in a sequence, is formed. By adopting the above-mentioned four-layer crimping structure of the small three-piece irregular can, the sealing performance of the can body is greatly enhanced, effectively improving the moisture-proof performance, thereby protecting the safety of food in the can.

A seamer assembly includes a frame, a first servo assembly, a second servo assembly, a first support element, a second support element, a first die, and a second die. The first servo assembly is coupled to the frame. The first servo assembly includes a chuck that is configured to be rotated by the first servo assembly. The second servo assembly is coupled to the frame. The first support element is configured to support a can subassembly that includes a can body and a lid relative to the frame where at least one of the first support element, the first servo assembly and second servo assembly move relative to the other of the first support element, the first servo assembly and second servo assembly. The second support element is coupled to the second servo assembly. The first die is coupled to the second support element. The second die is coupled to the second support element. The first support element is configured to support a can subassembly such that the chuck is received in a first chuck position. The first servo assembly is configured to selectively rotate the can subassembly when the chuck is received in the first chuck position. The second servo assembly is configured to selectively reposition the second support element such that the first die and the second die are correspondingly repositioned.

A sealing module for sealing a container opening of a container by a lid, the lid has a lid flange and the container has a container flange in the region of the container opening. The sealing module has a supporting unit with a supporting surface and a pressing unit with a pressing surface for pressing the lid flange together with the container flange of the container opening. The supporting unit and the pressing unit are displaceable relative to one another in an axial direction in such a way, so that the lid flange and the container flange are capable of being pressed together between the supporting surface and the pressing surface by an axially acting force in the operating state.

The present invention aims at closing a receptacle (1) provided with an opening (2) as tightly as possible while keeping low the amount of material required for a closure (3) used for this purpose. To this end, a tool (10) is suggested that closes the opening (2) of the receptacle (1) by means of the closure (3). The tool (10) comprises a tool plate (12) configured such that it is adapted to be introduced into the opening (2) of the receptacle (1). The tool further comprises at least one roll (11) that is arranged on the tool plate (12). The at least one roll (11) is adapted to be deflected radially outwards from a starting position into a closing position and returns to its starting position, so that a radial force can be caused to act on a closure rim (4) of the closure (3) for a limited period of time, the closure rim (4) being arranged between the at least one roll (11) and the receptacle inner side (5).
