Four Roller Bending Machine

3. Straight edge is short, so the effect of pre-bending is more suitable for cones.   
4. The rolling process can be finished in one operation, including pre-bending of the two sides and the four-roller veneer reeling. This machine is easy to operate and only requires one worker.
5. Meanwhile, this machine has the function of automatic position adjustment and clamping so that the boards will not slide.
6. The four roller bending machine avoids overload and protects from hydraulic pressure.
7. This machine is abrading-proof, there's no need to lubricate it.
8. The diameter of roller is narrow, the four-roller bending machine can produce barrels of a diameter 1.1 times as small as the upper roller’s. While, bending-oriented linear slide can produce barrels of a diameter from 0.5 to 1.4 times as large as upper roller. )

Features of Four Roller Bending Machine:
1. This machine has a better ability to produce barrel with smaller diameters than ones produced by other machines of the same standard. Moreover, it is energy-saving, it consumes less electricity than most of our competitors' machines.  
2. Two kinds of rolling available: Asymmetric rolling and Symmetrical roll. So it can process forward bending and backward bending.
3. The operational program is easy to use, so anyone can operate it.
4. The upper roller can be designed according to its use, and side rolls are all main drive.  
Operating Principle of Four Roller Bending Machine:
The centre of down roller changes the curvity of making plate along the curve track; meanwhile, it also changes the distance between two down rollers. So it will not slide with the range from lamina to nominal thickness plate.
Use of the Four Roller Bending Machine:
1. This machine is a lower adjusting 4-roller coiling machine which is manufactured by employing European advanced structural design.
2. It widely uses in manufacturing cylinders in many fields, for example, petroleum, chemical industry, boiler, steel industry, machinofacture and others.
