Five bite methods of lock former machine:

1. Single flat bite, used for joints of plates and longitudinal joints of ducts;

2. A single vertical occlusion, used for elbows, bends back and forth and the horizontal seams of winding pipes;

3. Single-angle occlusion, used for the longitudinal joints of rectangular ducts or parts, and the corners of rectangular elbows and three links;
