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.

a drive coupled to at least one respective drum proximal the front axial end thereof, for rotating the respective drum, the drive oriented offset from and not impeding the stock downstream transfer path; and
a cooling bed for receiving stock discharged from at least one respective drum.
19. The system of claim 18 , wherein at least one drive system defines at least one through-passage slot for unimpeded passage of stock therethrough along the downstream transfer path.
20. The system of claim 19 , wherein:
at least one drum has a plurality of drum channels oriented parallel to the drum rotational axis about a periphery of the drum; and
at least one drive system defines a plurality of respective through-passage slots aligned with each respective drum channel along the downstream transfer path.
