ABSTRACT:
A two-wire structure for use in suspending plastic bags on a rack is formed by inwardly bending each of the end portions of a single straight length of wire such that each lies against the middle portion thereof with their terminal ends butt welded together and with an upwardly directed looped protuberance formed on each end of the two-wire structure. Each end portion of the two-wire structure so formed is then bent to provide cantilevered support arms extending at right angles from each end of the middle portion thereof which forms the back of the two-wire structure by which the cantilevered support arms are attached to a rack. Such a construction provides the upwardly directed looped protuberances for use as safety precautions on the ends of the cantilevered support arms and further assures that each of the cantilevered support arms is provided with a continuous surface throughout its length. Such a continuous surface is needed to enable small mounting holes punched on the side handles of a stack of plastic bags in a flattened condition to pass over the end protuberances and slide along the cantilevered support arms during the storing and individual opening of the plastic bags in the stack.
