The first manufacturing stage (1) involves shaping and pressing the brake lining with an intermediate reinforcing layer and the lining carrier plate is tested for thickness, surface roughness, weight etc. The second stage (2) involves stretching and hardening the lining using electric heating and the current, voltage and temperature rise may be measured. The third stage (3) involves machining the linings to a flat surface. The fourth stage (4) involves scorching of the linings and temperature and emission of smoke and flames may be measured. The fifth stage (5) involves machining of beveled edges, grooves etc. The sixth stage (6) involves application of lacquer to protect against corrosion. The seventh stage (7) is an end control and checking stage. |
