ABSTRACT:
A stock rack of the type used in tire plants for transporting tread forming blanks and wherein a plurality of trays are supported on end upright supports and one or more intermediate upright supports for swinging movement between a generally horizontal position and a raised position. Each tray has a plurality of axially aligned rolled rim sections along its rear edge, the rolled rim sections being dimensioned to extend between adjacent ones of the upright supports and having adjacent ends spaced apart to receive an intermediate upright support therebetween. The upright supports have hinge rod receiving openings at vertically spaced locations therealong and hinge rods extend through horizontally aligned ones of the hinge rod receiving openings in the upright end and intermediate supports and through the rolled rim sections on a respective one of the trays. The hinge rod is secured against turning movement relative to the upright supports and the rolled rim sections on the tray have an internal cross-section sufficiently larger than the hinge rod to loosely receive the hinge rod so that the rolled rim sections on the rear edge of each tray turn on the hinge rod as the trays are moved between their lowered and raised positions.
