Roll Forming Machine Roll forming machines come in various types, depending on the type of profile being formed. The most common types are single-pair roll formers, double-pair roll formers, and multi-pair roll formers. Single-pair roll formers have one set of rollers that form the entire profile shape. Double-pair roll formers have two sets of rollers working in tandem to form the profile shape. Multi-pair roll formers have multiple pairs of rollers that work simultaneously to form complex profiles. Roll forming machines also come with different features that enhance their performance. Some machines have auto shear units that cut the metal strip to the required length, while others have hydraulic presses that form the metal into embossed patterns. Roll forming machines can also be equipped with computer-controlled systems, which allow operators to set and adjust the forming process parameters.
