Friction generating device and method of making the same |
摘要 |
A friction lining for use in the clutch plate of a friction clutch or a multiple wrap brake band for use in an automatic transmission is obtained by adhesively securing one side of a friction generating second layer to one side of a metallic first layer. The necessary incisions in the form of cuts, slots or slits are made from the exposed side of the second layer in a direction toward the exposed side of the first layer by resorting to one or more high-energy streams, such as laser beams, electron beams or liquid jets. Each incision can be made in one or more stages by a single stream or by a series of successively applied streams.
