Roll Bending Machine: A Versatile Solution for Metal Profile Bending

The roll bending machine, also known as the angle roller, angle roll, or angle roll machine in the Americas, and as the section bending machine in some regions, is a vital tool used in the metalworking industry. In certain areas of China, it may be referred to as the “rolling round machine” or “rolling bending machine.” This article aims to explore the various names, applications, and versatility of the roll bending machine.

Understanding the Terminology

In different regions and industries, the naming conventions for the roll bending machine can vary. In the Americas, it is commonly referred to as the plate rolling machine, plate bending machine, plate roller, profile bending machine, angle roller, angle roll, or angle roll machine due to its ability to bend metal angle bars or profiles. In other parts of the world, such as Europe, it may be known as the section bending machine, emphasizing its capability to bend various types of metal sections. In specific areas of China, local terms like “rolling round machine” or “rolling bending machine” are used to describe this equipment.


The roll bending machine finds extensive applications across multiple industries, including metalworking, fabrication, construction, and manufacturing. Its primary function is to bend metal profiles, such as angle bars, tubes, and beams, into curved or circular shapes. This versatility makes it suitable for producing components used in diverse applications, such as architectural structures, machinery, furniture, and more.

Working Principle

The roll bending machine operates on a triangular configuration consisting of two fixed bottom rolls and one adjustable top roll. The metal profile is positioned between the bottom rolls, while the top roll applies pressure to initiate the bending process. By adjusting the position of the top roll, the desired curvature can be achieved, allowing for precise and efficient profile bending.
