Abstract

A method of forming a rebar coupling is disclosed. The method comprises of cold forming an end portion of a rebar to flatten any projections thereon and obtain a diameter of the end portion larger than the inner diameter of a coupler to be mounted thereon. The method further comprises of smoothening at least a part of the cold formed end portion of the rebar by a turning operation to a shape and diameter suitable for engagement with the coupler and forming threads on at least a part of the turned portion of the rebar by a rolling operation.
