  • Method of reducing thickness of unbroken rolling stock
    Publication number: 20090095045
    Abstract: A method of reducing thickness of unbroken rolling stock (14) by longitudinal rolling includes deforming the rolling stock (14) in the width direction with deformation regions (26 to 29; 86 to 88) of the rolls (22 to 25; 82 to 84) penetrating in the rolling stock to the same depth.

  • Process of producing profiles whose cross-section is variable in the longitudinal direction
    Patent number: 7418849
    Abstract: A process of producing profiles whose cross-section is variable in the longitudinal direction, characterised by the process stages of cutting a blank 31 with a substantially constant width along a longitudinal direction, deforming the blank 31 by deep-drawing to form an open profile whose cross-section is variable along the longitudinal direction, and cutting the flanges projecting from the open profile.

  • Open elongate profile
    Publication number: 20070248793
    Abstract: An open elongate profile has side walls (12, 13; 22; 32) oriented relative to each other in a direction of a longitudinal extension (L) of the side walls, with at least one of the side walls (12; 22; 32) having at least one thickness-reduced region (14; 24; 34) along its longitudinal extent (L) and a shaped profile (15; 25; 35) provided in the at least one thickness-reduced region (14; 24; 34) of the at least one of the side walls (12; 22; 32).
