Roll Forming Handbook
edited by George T. Halmos

Roll Forming Handbook presents the first comprehensive, dedicated treatment to all facets of roll forming, supplying references to more in-depth information to fill in the gaps.

Features:

  • Includes real-world case studies, recommendations for efficient plant layout and material handling as well as hundreds of illustrations and references
  • Explains the principles and methods of manual and computer-aided roll design and tool setup
  • Supplies equations to calculate number of passes, shaft diameters, and bending factors, published here for the first time
  • Presents guidelines for training personnel as well as for performing troubleshooting and maintenance
