  • Patent number: 10239705
    Abstract: A conveyor for can blanks, having a machine frame, on which at least one conveyor drum is supported so that it can rotate about an axis of rotation, wherein the conveyor drum on an external circumferential surface is provided with a plurality of can holders in each case supported parallel to the axis of rotation so that they can move linearly, and having at least one actuator system associated with the conveyor drum, configured to impart a linear movement to at least one can holder. It is provided that the at least one actuator system is configured to provide the linear movement of the at least one can holder as a predefinable function of a rotational position of the conveyor drum in relation to the machine frame.

  • Patent number: 9358648
    Abstract: A processing apparatus for container blanks, with a machine bed, a feed device for feeding container blanks, a discharge device for removal of container blanks, a rotatably mounted rotary worktable with several locating devices designed for conveyance of container blanks along a circular orbit section shaped conveyance path, wherein the conveyance path determines a first circle segment shaped surface section, several operating devices lying opposite the rotary worktable in the radial direction, and at least one conveyor designed for conveyance of components of container blanks and/or for container blanks along a conveyor section between a component mounting and an assigned operating device. The component mounting of the conveyor is located in a second circle segment shaped surface section, which supplements the first surface section determined by the circular orbit section shaped conveyance path to make a full circle.
