ABSTRACT:
A workpiece issuing from a rolling mill is directed by a tubular guide to pass above the knives of a flying shear that is driven in a drive train used to rotate a cam used to pivot the guide tube and direct the workpiece into the shear. The workpiece moves beyond the shear into one of a plurality of retardation channels formed in a drum. There may be shock absorbers at their remote ends to prevent escapement of the sheared workpieces in the event they fail to stop by sliding friction. The drum rotates at a relatively slow speed. When a trailing end of a sheared workpiece moves beyond the shear into the drum, the leading end of the remaining length of workpiece enters a laterally-adjacent channel which has moved into the path of travel by the workpiece through rotation of the drum. A conveyor receives workpieces discharged from the drum through rotation thereof and carries them to a remote discharge station where they are loaded into a cradle car.
