1. A method comprising:
- collecting, at a collection station, loose feed scrap;
feeding the loose feed scrap to a compression station in a feed direction where the loose feed scrap is compressed into a compressed feed scrap having a density higher than a density of the loose feed scrap;
feeding the loose feed scrap to a twisting station where the loose feed scrap is twisted into a bound feed scrap having a substantially continuous length greater than a length of the loose feed scrap, wherein the twisting station comprises a plurality of rollers disposed at two oblique angles to the feed direction, and wherein each of the plurality of rollers comprise a plurality of teeth extending therefrom;
feeding at least one of the compressed feed scrap and the bound feed scrap to an exit station, wherein the at least one of the compressed feed scrap and the bound feed scrap exit the exit station as a rope of scrap; and
delivering the rope of scrap to a melter system.

Abstract
A method of forming a rope material from a loose feed scrap includes a number of operations to mechanically bind the loose feed scrap. The feed scrap is collected. The feed scrap is twisted and compressed, operations that may be performed simultaneously. This twisted and compressed feed scrap, now in the form of a rope material, is then fed into a melter system.

10. A method comprising:
-
collecting a feed scrap; twisting the feed scrap; substantially simultaneously with twisting the feed scrap, compressing the feed scrap with a plurality of rollers disposed at two oblique angles to a feed scrap direction, so as to form a substantially continuous rope; and feeding the twisted feed scrap and the compressed feed scrap into a melter system. - View Dependent Claims (11, 12, 13, 14, 15)

16. A method of forming a rope material from a loose feed scrap, the method comprising:
substantially simultaneously advancing, twisting, and compressing the loose feed scrap through a twisting and compression station comprising a plurality of rollers disposed at two oblique angles to a loose feed scrap direction, wherein the loose feed scrap is advanced through the twisting and compression station until the rope material is formed.
