Abstract
An improvement to continuous annealing furnaces allows three stacks of coils to be loaded on two trays, with one of the stacks straddling the trays. The modifications include an upender device adapted to place the stacks of coils appropriately on two side-by-side trays, a tray pusher device which ensures that the trays will remain in side-by-side alignment throughout their traverse of the furnace, and a downender device adapted to receive the three stacks of coils from the furnace after annealing, and rotate them to an axis-horizontal position from which they can be removed by a boom truck.
