A liner machine for applying a sealing compound to a can end or lid. The liner machine includes a motor drive dual turret system. The turret system is installed at the top of a table or platform surface and two turrets rotate in opposition directions from one another, simultaneously or independently at same or different times. Each turret includes a plurality of workstations which extend out from each turret facing away from each other. The workstations receive an individual lid, which is delivered via a starwheel from a downstacker to each turret system. Each rotates in a direction that is opposite the direction that its respective turret system rotates, and in a direction that is opposite the direction that the other starwheel rotates. Sealant injectors in the turret systems apply sealant to each lid as the lids rotate around each turret system.

A dispensing system for a rotary dispensing machine includes a tank, a fill tube, and a piston that moves along the fill tube and defines an air chamber and a fluid chamber within the tank. The tank is rotatable relative to the fill tube. A fluid is dispensed from the fluid chamber of the tank through at least one outlet formed in the tank.

A metal closure for containers comprising a capsule designed to be applied to an opening of a container and including a circular part from which extends a perimeter edge. The perimeter of the edge has a rounding or folding obtained by curling and has a series of deformations made in a radial direction towards the centre of the capsule for forming the seal.

A sealing machine and method for controlling a sealing machine Includes the following steps: placing capped containers provided with a seal on plates, rotating the plates, pressing the seal against the cap of the container and fastening said seal using a sealing head. The step of rotating the plates is performed by rotating each plate independently of the other plates. The method further includes: detecting at least one parameter associated with the rotation of a plate and/or with a compression load between each sealing head and the seal, and comparing the value of the detected parameter with a reference range.

An apparatus includes a tool operable to releasably join a metallic end closure to a metallic container. In one embodiment, the tool is configured to form a thread in the closure and the container. The tool may optionally crimp the closure to the container. Once sealed, the container can be opened by rotating the closure in an opening direction. The closure can subsequently re-close the container by rotating the closure in a closing direction.

A rotary tank assembly is provided for a liner. The liner is structured to apply a compound to a plurality of container closures. The rotary tank assembly includes a compound tank, a fill tube structured to fill the tank with a volume of the compound to a desired level, a sensor assembly adapted to measure the level of the compound within the compound tank, and a rotary union assembly structured to pivotably couple the fill tube and the sensor assembly to the compound tank. The sensor assembly only requires one single probe.
