Abstract
A method and apparatus for producing steel bars that are cut to length in response to a customer order. The method includes producing a continuous length of steel bar from a rolling mill, cutting the continuous length of steel bar into successive segments, each representing a multiple of the length of the bar of the customer order, cutting the segments in in-line cold shears first into two times the length of the bar of the customer order and then in half into lengths equal to the length of the bar of the customer order while maintaining the production of the continuous length of steel bar produced by the rolling mill, and bundling the bars of the length of the customer order for discharge from the mill.
