工作原理：上辊可以垂直移动和水平移动。预弯通过上辊水平移动使上辊相对于

Working principle: <br>the roller can be moved vertically and horizontally. <br>By pre-bending the roll so that the horizontal movement of the roller relative to achieve asymmetrical position of the lower roller. <br>Curling processed by an electric motor, reducer drive the two rollers. <br>Since the elevation of the roller constant, and the feed operation is facilitated.

How it works:<br>The rollers can move vertically and horizontally.<br>Pre-bending is achieved by moving horizontally on the upper roller so that the upper roller is in an asymmetrical position relative to the lower roller.<br>The round processing is carried out by driving two rollers by electric motors and gearboxes.<br>Because the height of the lower roller is unchanged, it is convenient for feeding and operation.

working principle:<br>The upper roller can move vertically and horizontally.<br>Pre bending is realized by the horizontal movement of the upper roll so that the upper roll is asymmetrical with respect to the lower roll.<br>The coiling processing is carried out by two rollers driven by motor and reducer.<br>Since the elevation of the lower roll is constant, it is convenient for feeding and operation.<br>
