  • Patent number: 5235839
    Abstract: A flanging head assembly having a cluster of freely rotatable spin flanging rollers includes a stop ring against which the flange hits during the final flange forming stages to limit the flange to a specific diameter. To prevent the flange from entering the crack formed between the rotating roller and the stationary stop ring, there is provided a step spacing the stop ring surface from the roller forming surface. In this manner, as the terminal edge of the flange slides around the flanging roller during final forming, it will pass over the crack and across the step to lodge in a corner formed between the step and stop ring surface. In a preferred embodiment, the step is a conical surface extending from the stop ring surface in a direction away from the can bottom. This conical surface extends radially inwardly a sufficient distance to contact unsupported flange portions between the flanging rollers to limit the degree of elastic sagging of these portions.

  • Patent number: 5042289
    Abstract: End closure for a container is tested for pneumatic pressure required to buckle or rupture it, by applying pneumatic test pressure to one face of the closure, and using that pressure to press an annular peripheral area of the opposite face of the closure against a support to establish a seal without gripping the closure mechanically.

  • Patent number: 4911323
    Abstract: An umbrella type resealable closure device is described. A metal container includes an end wall with a flanged region substantially surrounding a scored portion defining an openable panel. A resealable closure device incorporates a non-hooking closure structure on one side and a structure for separating the openable panel from the end wall on the opposite side.

  • Patent number: 4741166
    Abstract: An apparatus is disclosed for regulating a liquified gas input stream for temperature and pressure. The apparatus produces a pressurized head of liquified gas while removing gaseous material to produce a constant temperature and pressure liquified gas exit stream.

  • Patent number: 4407340
    Abstract: An apparatus is disclosed for pressurizing containers by injecting predetermined amounts of liquified gas into the containers. This device includes an injection unit having a combination float-pressure regulating means which employs the vapor pressure of evaporating liquified gas to its gaseous state from its liquid state to control liquified gas level and gas pressure within the device.

  • Patent number: 4246300
    Abstract: Can bodies are held by means, such as a vacuum, magnetic or other means onto rotating, disc-shaped pads which accompany the cans throughout an indexing route. A can centering guide positions each can on the center of one of the pads to insure eventual alignment with spray guns at two spray stations downstream. A spinner-drive belt encircles a turret and forms a substantially continuous rotational drive for spinning the can-bearing pads. When a vacuum means is employed, the vacuum means comprises a vacuum manifold in the rear of the turret and has manifold groove for vacuum communication with the can through the vacuum pad. As the can-bearing vacuum pads pass along the manifold groove, the cans, being securely centered on the vacuum pads, rotate at the same velocity as the belt-drive vacuum pads.
