  • Rotary machine with separately controllable stations
    Patent number: 8261631
    Abstract: A rotary machine may have multiple stations that have a linear motion operated by a cam and a rotational motion operated by individual motors mounted on each station. Each station may perform a motion profile that is proportional to the machine's central axis rotation or, in some cases, independent of the central axis rotation. In some embodiments, each station may rotate to orient a part prior to processing. In one embodiment, the cam driven linear motion may enable a station to lower for loading and unloading, then raise for processing. The rotary machine may have various mechanisms at each station for processing a part. One such embodiment is a rotary machine that may be outfitted with compound dispensing mechanisms at each station.

  • Apparatus for detecting a defect in container end manufacture
    Patent number: 6250135
    Abstract: Apparatus for detecting a defect during the formation of a container end having a stay-on-tab secured thereto, particularly when the defect is associated with a mis-located tab, in which a portion of the apparatus will be moved by the defect which movement is sensed and a signal is generated.
