  • A rundown on rolling machinesThe FABRICATOR

    Oct 04 2010 · A Closer Look at Machine Styles. Three-roll initial-pinch (see Figure 5) or single initial-pinch plate rolls generally are for light-capacity applications and may be electromechanical or hydraulic. They work by pinching the flat sheet between two vertically opposed rolls while the third offset roll—or bending roll—moves upward to contact and then bend the sheet.
