ABSTRACT:
A method of producing a metal bar having one edge serrated wherein a billet work-piece of metal is heated and passed through stands of a hot rolling mill so as to elongate the billet into a bar and form the bar to a generally rectangular shape, supporting the side faces of the bar in a notching stand near the output end of the mill, supporting one edge of the work-piece in the notching stand by one roll of that stand, forming serrations in the other edge of the bar in the working zone by engaging that other edge with outstanding teeth of the second roll, and subsequently passing the work-piece through a further stand to flatten the work-piece side faces and size the work-piece.
