  • Publication number: 20130081437
    Abstract: A rolling mill coil-forming laying head system elongated hollow pathway Or pipe structure defining an inner surface for transport of elongated materials is formed by the process of bending the pathway structure at near constant temperature, such as at near ambient temperature, preferably without application of external heat. In some embodiments, the method utilizes an automated bending machine, preferably under computer numerical control (CNC) that executes stored bending constructions to conform the pathway structure to a desired profile. The bending instructions may be modified so that the actual bending profile conforms to a desired profile. In this manner subsequent path structures may be formed, that have uniform physical properties.

  • Publication number: 20130074567
    Abstract: A rolling mill rotating entry system (RES) with at least one front end-driven drum that indexes alignment of the RES guide path and drum with the bar stock transfer guide path. The front end drive system is offset from the bar stock transfer path, so that the bar stock has sufficient clearance to enter the guide path. The front end drive system facilitates desired indexed alignment of the RES guide path and the bar stock transfer path without the need for front end braking or damping systems that are customarily used with rear driven drums in known RES systems. Other RES embodiments include a rear drive system that drives the drum in tandem with the front drive system.
