The present invention has an object of providing a seaming device that can prevent the leakage of a lubricating oil from the in-machine housing of a chuck unit into a seaming operation space, prevent the occurrence of a defective product contaminated by the lubricating oil, and eliminate heat elongation due to heat generation to accurately maintain a seaming dimension. Provided is a seaming device (100) including: a chuck unit (320) that positions a lid (F) mounted on a can C; and a seaming unit (410) that seams the lid to the can, wherein the chuck unit has a spindle (325) having a chuck (321) for positioning the lid attached at a lower end thereof, a bearing (326) that rotatably supports the spindle, and a non-contact type oil seal mechanism for sealing between the spindle and the in-machine housing at a position below the bearing.

A gassing device for gassing a container includes a rotatable gassing rotor with a container receptacle for receiving the container and a feeding area for feeding a gas via a feed opening. The container receptacle includes a gassing nozzle flow-connected to the feed opening via a channel for gassing the container, and a stationary gas supply with a stationary supply opening arranged on the feeding area such that the supply opening can be flow-connected to the feed opening. The gassing rotor can be supplied with the gas from the gas supply in the operating state by moving the feed opening to the stationary supply opening by rotating the gassing rotor. The feeding area is connected without contact to the gas supply in the form of a labyrinth seal, so that the gassing rotor is rotatable relative to the gas supply in the operating state.

A seaming device includes a seaming head for fixing the lid to the container, first and second seaming rollers and a rotary drive. The seaming head is arranged between the first and second seaming rollers such that the container with the lid is fixed centered between the first and second seaming rollers in the operating state. The rotary drive is drive-connected to the first and second seaming rollers, the first and second seaming rollers rotated about the seaming head by the rotary drive, so that, in the operating state, the first and second seaming rollers are moved along a circumference of the container immovably fixed by the seaming head, and a container flange of the container are seamed with a lid flange of the lid.

An apparatus for producing a cylindrical secondary battery cell including a battery can in which an electrode assembly and an electrolytic solution are accommodated, a cap plate coupled to the battery can, and a gasket located between the battery can and the cap plate includes: a support member into which the cylindrical secondary battery cell is inserted in a state where an end portion of the battery can and an end portion of the gasket are arranged to face a preset direction and the cap plate contacts the gasket; at least one fixing member configured to fix the cylindrical secondary battery cell moved to a preset position by the support member; and a forming member located over the cylindrical secondary battery cell fixed by the fixing member and rotating and pressing the end portion of the battery can to form a crimping portion.

A can seaming apparatus comprising a frame, a can handling assembly and a can seaming assembly. The frame has a bottom end and a top end, an upper mounting plate and a lower mounting member. The can handling assembly has an upper chuck and a lower chuck, the upper and lower chucks configured to releasably retain a can and top therebetween. The can seaming assembly includes a roller frame with a first and second roller, wherein the first and second rollers are directable into contact with the can and top while being retained by the upper and lower chucks. The upper chuck is fixed to an axle that extends through the upper mounting plate, and is rotatably coupled to the upper mounting plate. The axle extends beyond the upper mounting plate and structurally configured to be free from obstruction sufficient to allow a for the operable attachment of a chuck of a power tool. A combination can seaming apparatus and power tool is likewise disclosed, as are methods of operation.

A seaming roller cleaner includes a base body, on which a driven roll receptacle and a non-driven roll receptacle are mounted. The roll receptacles are used to receive paper web rolls. The paper web roll includes a cleaning web, and the base body provides a support over which the cleaning web is laid to define a cleaning surface. The cleaning web is drawn by the driven roll receptacle in the direction of the driven roll receptacle. The non-driven roll receptacle is passively rotated and may be slightly braked to prevent rotating too quickly. The support includes a carrier plate and an elastomer. The seaming roller may be arranged at an oblique angle relative to the direction of the cleaning web is drawn, such that the seaming roller is wiped and slowly rotated by the cleaning web.
