Rotary Slitting Principles and Applications, Part 3

THE MACHINES Although design details vary, slitting installations fall into either of two very distinct design styles. A good many lines for light gauge, small coils of narrow width (Fig. 17) have the slitter and recoiler assembled on a common base....
