| 摘要 |
<p>The invention concerns a method for making a ring-shaped friction facing, in particular for a clutch, made of a friction material comprising fibers, said method consisting in injecting a material (M) into a mould with two parts (11, 21, 31, 41, 51-12, 42, 52) axially mobile relative to each other and defining, when they are mutually attached, an impression (13) corresponding to the desired ring shape; the supply of the impression with material (M) being carried out by a channel extending up to the impression from an injection point (17) located on or very near the axis (A) of the impression (3), said channel being defined between the two mould parts and having a circular shape. The invention also concerns an injection mould for implementing said method and the resulting friction facing.</p> |
