What is the purpose of a bending leaf in a cornice brake?

The purpose of a bending leaf in a cornice brake is to create folds in the metal. The bending leaf is a critical component that allows the machinist to accurately bend metal sheets at various angles, enabling the formation of complex shapes and folds as needed in sheet metal work. By adjusting the position of the bending leaf, different sizes and types of bends can be made, which is essential in creating seams, edges, or integrated features in metal fabrication. This functionality is key in tasks such as making gutters, ducts, and other custom metal applications where precise bends are required. Understanding the role of the bending leaf will enhance your ability to effectively use a cornice brake in your work.
