Abstract
A method for roll-forming disk carriers or the like, which are designed as a pot-shaped sheet metal part having inner and outer teeth, wherein a multitude of cassettes is equidistantly arranged on the circumference of a roll-forming tool, said cassettes having profile rollers arranged in their interior, which roll out the disk carrier to be formed with their outer circumference and thus impart toothing on the disk carrier to be formed, wherein the forming depth of the profile rollers at the disk carrier to be formed is designed in such a way that a narrow, peripheral, self-contained, unformed bridge remains between the inner diameter and the outer diameter of the toothing, wherein the bridge increases the engine-speed strength of the disk carrier as a hoop band cylinder that is integrated into the toothing.
