Anatomy of a Roll Forming Line - Part 2 of 4: Coil Straightening & Pre-Punch

Part 2 of 4: The second step in the continuous roll forming line is leveling and straightening the metal with coil processing equipment. The straightener removes defects such as bow, camber, and twist. After coil straightening, a pneumatic punch press feeder pulls the strip into a pre-punch press. The servo controlled feeder is accurate to 0.001”. In the pre-punch press, a die punches specifically designed holes through the strip. Industry-leading AMS controls ensure the process is always running at maximum speed and precision.The holes punched by the die will be used to detect cutoff times down the line.
