Method for producing elongated, peripherally contoured shaped blanks from a metal strip

Abstract

In the method for producing from a metal strip peripherally contoured, elongated shaped blanks ( 6 ) having regions of different thickness along their length (L 1 ), starting blanks ( 3 ) are first stamped from a metal strip having a constant thickness wherein the starting blanks are arranged at interleaved positions in the longitudinal direction of the metal strip. The starting blanks are subsequently guided separately through a rolling mill ( 5 ) with a longitudinal orientation and rolled in the rolling mill ( 5 ) into shaped blanks ( 6 ) having regions of different thickness.

         6 . A method for producing peripherally contoured, elongated shaped blanks with longitudinal regions of different thickness from a metal strip, comprising the steps of:
 defining on the metal strip positions of starting blanks with an interleaved arrangement, said starting blanks having a longitudinal direction and a thickness;   stamping the starting blanks out of the metal strip;   rolling the stamped-out starting blanks separately along their longitudinal direction in a rolling mill to form shaped blanks having regions of different thickness along the longitudinal direction of the shaped blanks.   
     
     
         7 . The method of  claim 6 , wherein the stamped-out starting blanks have a periphery with an essentially T-shaped contour and the interleaved arrangement of the starting blanks forms one of a transverse or longitudinal pattern with respect to a lengthwise direction of the metal strip. 
     
     
         8 . The method of  claim 6 , wherein the starting blanks pass through the rolling mill with a pretension applied in the longitudinal direction of the starting blanks. 
     
     
         9 . The method of  claim 6 , and further comprising the step of:
 measuring the thickness of the starting blanks before insertion into the rolling mill and   rolling the starting blanks in the rolling mill to form the shaped blanks by taking into consideration measured thickness tolerances.   
     
     
         10 . The method of  claim 6 , wherein the starting blanks are stamped from a metal tape unwound from a coil.
