thermoplastic blending by two roll mill

3 Roll Bending Machine (Working Principle and Rolling Process

This method uses the die to prebend two ends of the steel plate at the pressure machine to achieve the desired curvature. Keep allowance: Add appropriate plate allowance at plate ends. After the two ends roll out a certain length, then cut off the remainder (also known as the straight-line segment). Add base plate for pre-bending
