A Plate Rolling Machine is a machine that will roll different kind of metal sheet into a round or conical shape.〔(Link text ), CMF Jammes professional manufacturer of Plate Rolling Machine.〕 It can be also called “Roll bending machine” “plate bending Machine” or “rolling machine” They are different kinds of Technology to roll the metal plate: 1.4 Roller machine: Anatomy; a Top-Roll, the Pinching-Roll, and two Side-Rolls. The flat metal plate is placed in the machine on either side and "pre-bent" on the same side. The Side-Rolls do the work of bending. The Pinching Roll holds the plate. 2. 3 Roll Machines (Variable Pitch aka Variable Geometry): Anatomy; One Pressing Top-Roll, Two Pressing Side-Rolls The 3 Roll Variable Pitch aka Variable Geometry works by having all three rolls being able to move and tilt. The Top-Roll moves on the vertical plane. The Side-Rolls move on the horizontal plane. When rolling, the Top-Roll presses the metal plate between the two Side-Rolls. The advantage of having the Variable 3 Roll is the ability to roll many thicknesses and diameters of cylinders. For example; The Side-Rolls are what produce the mechanical advantage. With the Side-Rolls all the way open, then you have the maximum mechanical advantage. With the Side-Rolls all the way in, you have the least mechanical advantage. So, your machine has a capability of rolling 2" thick material with the maximum mechanical advantage, but your job is only 1/2" thick. Simply reduce the mechanical advantage and you have a machine that can roll from 1/2" ~ 2" thick. == References == 〔 2. (MG s.r.l.
