ABSTRACT:
A metal collar which is used to construct a coupling for a flexible pressure hose includes a plurality of inner annular beads which are formed by a single stamping operation. Each inner bead is formed to define an annular flat surface facing one end of the collar, and which assists in gripping the hose end. When formed, the collar will also include a plurality of corresponding outer annular grooves opposite the inner annular beads. The stamping operation is performed by a forming apparatus which includes a collapsible, segmented outer die assembly and a coaxially positioned expandable inner die assembly. Due to the segmented construction of the die assemblies, the annular flat surfaces of each of the beads are not continuous, but are formed with a plurality of circumferentially spaced interruptions.
