Roll Forming Machine Guide for Steel Roofing Sheets
Roll forming is a continuous bending operation in which a long strip of sheet metal (typically coiled steel) is passed through sets of rolls mounted on consecutive stands, each set performing only an incremental part of the bend, until the desired cross-section profile is obtained. Here’s a detailed look at the roll forming machine guide:
Working Process of Roll Forming Machines
- Decoiling: The metal coil is fed into the machine.
- Feeding: The material is continuously fed into the roll forming machine.
- Roll Forming: The material passes through various rolls which bend it into the desired shape.
- Cutting: The shaped metal is cut to the required length.
- Collecting: The finished product is collected and prepared for shipping.
