1). Bending roll 2). The top and bottom roll can be adjusted parallel 3). Simple and practical Product detailed description: 1). Rolling machine, plate bending machine, plate roll, bending roll, roll bending machine, plate bending roller. 2). This machine structure is a three roller symmetrical type. 3). The roll in the two lower rollers symmetrical position for the vertical movement, through the silk and silk worm drive female, the two lower rollers, through the output gear reducer with the top gear, Provide torque. 4). The disadvantage is that the aircraft need to rely on other devices end plate pre-bending.
