A variable thickness roll forming system for forming a variable thickness blank including at least two sets of cylindrical shaped rollers. Each of the sets of rollers include: a first roller including a face which is linear where the first roller contacts the metal sheet; and a second roller including multiple shaping faces positioned about a perimeter and directed toward the face of the first roller. Each roller set incrementally alters a thickness of a metal sheet in a direction transverse to a metal sheet feed direction when the metal sheet is passed between the first and second rollers. The metal sheet after passing between the first and second rollers forms a roll formed blank having a first portion and a second portion positioned in the direction transverse to the feed direction with respect to the first portion, the first portion thicker than the second portion.

A shaped roller for a profiling line, comprising a conical portion (2) and an end portion (3), concentric with respect to a rotating axis (Z), wherein the conical portion (2) is equipped with a vertex section (23), and wherein the end portion (3) has a greater diameter than the vertex section (23) that defines a shoulder from the surface of the first conical portion (2).

The present disclosure relates to an asymmetric rolling device capable of enhancing a physical property of materials and may include: a first work roll contacting a first surface of a material to be rolled; a second work roll contacting a second surface of the material to be rolled and having a second radius greater than a first radius of the first work roll so as to asymmetrically roll the material to be rolled; a drive roll contacting the first work roll and formed above or below the first work roll so as to drive the first work roll; a driving device driving the second work roll or the drive roll; and a first idle roll contacting the first work roll and formed at a front or a back of the first work roll to support the first work roll in a longitudinal direction of the material.
