Carriage Board Roll Forming Machine

Carriage board, also known as top hat or C-profile, is a versatile roll formed section used extensively in light steel framing for walls, floors, roofs and other building components. Carriage board roll forming machines are designed specifically to produce these hat channel profiles efficiently.

This guide provides a comprehensive overview of carriage board roll formers covering their working, types, specifications, applications, advantages, and more.

Introduction to Carriage Board Roll Forming Machines

Carriage board roll forming machines are a specialized type of metal roll forming equipment engineered to produce top hat or C-profiles from coiled steel strips.

Key features:

  • High productivity continuous processing
  • Capable of high forming speeds
  • Quick changeover between profiles
  • Durable construction for heavy industrial use
  • Advanced drives for precision and efficiency
  • User-friendly controls and operation

Carriage board profiles are an important light gauge steel framing component for wall studs, floor joists, roof trusses and other structural parts in residential and commercial construction.

Roll forming is an ideal process for producing lengths of uniform carriage board in bulk in different sizes.

Working Principle of Carriage Board Roll Formers

Carriage board roll forming machines operate on the principle of incremental bending of strip material through a series of roller stations to gradually form the hat-shaped cross-section.

The key processes involved are:

  • Coiled steel strip fed into the roller forming section
  • The strip passes through a series of roller stations
  • Rollers progressively bend the strip through calibrated angles
  • Forming flanges and web until final C-profile is achieved
  • Formed profile cut to length by built-in cutoff press
  • Formed boards stacked for next process

Advanced tooling design allows fast changeovers between different carriage board dimensions through quick roller changes.
