  • Method and apparatus for shaping fiber mats
    Patent number: 4415517
    Abstract: Method and apparatus for shaping of mats composed of loose fibers with a thermosetting resin interspersed throughout. The apparatus compresses the mat and exposes its laterally extending surfaces to elevated temperatures to obtain partial curing thereof. Slits are made in the surface regions adjacent areas where extra shaping will occur in forming the final product. These slits enable more precise shapes to be impressed upon the mat and eliminate the tendency of the partially cured areas to spring back to a position of lesser compression.
