ABSTRACT:
A hanger for use in a conveyorized system for transporting limp sheet material has a gripper assembly for quick loading and unloading of a unit of work material onto or off of the hanger and includes a longitudinally slidable gripping element cooperating with a fixed gripping surface urged toward the fixed surface by biasing device and is selectively actuated by fingertip pressure exerted on two laterally outwardly extending flanges respectively extending from a body portion supporting the gripping element and a top portion of the gripping element. The hanger may employ a carrier supporting a plurality of gripper assemblies oriented in a spaced relationship with one another and having means by which the orientation of each of the gripper assemblies may be changed.
