Abstract
Abstract This disclosure relates to a movable support for moving and positioning can bodies and like tubular members with respect to components of an automatic coating and printing machine. The movable support includes an endless conveyor having special members at regularly spaced intervals and a mandrel carried by each special member for rotation, each special member including hub means having link elements pivotally mounted thereon, and there being chain sections including a plurality of pivotally connected links extending between adjacent ones of the special members with the chain sections being pivotally connected to link elements which, in turn, are pivotally mounted on the hub. The movable support is reversibly flexible so as to be movable about sprockets in opposite directions.
