The thickness of the web may be changed with a corresponding change in the flange width. All other dimensions

Design the Layout and Roll Tooling. After completing the flower, you need to choose drive diameters and check for maximum flange roll sizes and possible interference with the rolling mill. During the design phase, you'll need to consider increasing the pitch diameters of the rolls from pass to pass (also called step-up).BASIC ROLL-FORM TOOLING DESIGN: PROCESS OVERVIEW, INSTRUCTION, AND TIPS. 1.0 INTRODUCTION. This paper is intended to provide "basic" Roll Forming Tooling design instruction and tips for the beginning or novice designer. In my experience, the ideas expressed in this report can be applied to many situations, but I will stop short of claiming that these are the only solutions.
