Claim 1
Independent Claim
112 words
A METHOD OF ROLLING AN ELONGATED METAL BODY TO FORM A PROFILED CROSS SECTION, SAID METHOD COMPRISING THE STEPS OF HEATING SAID BODY TO A DESIRED ROLLING TEMPERATURE BY PASSING A PREDETERMINED ELECTRIC CURRENT THROUGH A PREDETERMINED LENGTH THEREOF, PASSING THE HEATED BODY IN A SINGLE PASS THROUGH A ROLL GROOVE DEFINED BETWEEN ROLLS OF A ROLLING STAND TO ROLL SAID BODY INTO SAID PROFILED FORM, AND CONTINUOUSLY REGULATING THE TEMPERATURE TO WHICH SAID BODY IS HEATED IN ACCORDANCE WITH THE DEGREE OF FILLING OF SAID ROLL GROOVE BY SAID BODY, SAID TEMPERATURE BEING INCREASED WHEN SAID ROLL GROOVE IS OVER FILLED AND BEING DECREASED WHEN SAID ROLL GROOVE IS INSUFFICIENTLY FILLED.

Claim 3
Dependent Claim
151 words
APPARATUS FOR ROLLING AN ELONGATED METAL BODY IN A SINGLE ROLLING PASS TO FORM A DESIRED PROFILED CROSS SECTION, SAID APPARATUS COMPRISING A ROLLING STAND HAVING TWO ROLLS WHICH BETWEEN THEM DEFINE A ROLL GROOVE FOR ROLLING SAID DESIRED CROSS SECTION ON SAID BODY, TWO SPACED ELECTRICAL CONTACT MEANS ENGAGING SAID BODY FOR PASSING A PREDETERMINED ELECTRIC HEATING CURRENT THROUGH A PREDETERMINED LENGTH OF SAID BODY BEFORE ROLLING TO HEAT THE BODY, THE DISTANCE BETWEEN SAID CONTACT MEANS AND THE MAGNITUDE OF SAID CURRENT BEING ADJUSTABLE, WHEREBY SAID BODY CAN BE HEATED TO A DESIRED ROLLING TEMPERATURE, MEANS FOR MEASURING AT LEAST ONE DIMENSION OF SAID BODY AFTER ROLLING, MEANS FOR DETERMINING THE DIFFERENCE BETWEEN SAID DIMENSION AND A PREDETERMINED DIMENSION, AND MEANS FOR VARYING THE MAGNITUDE OF SAID HEATING CURRENT FOR ADJUSTING THE TEMPERATURE TO WHICH SAID BODY IS HEATED BY SAID HEATING CURRENT SO AS TO REDUCE SAID DIFFERENCE.
