ABSTRACT:
A shaping apparatus for the production of fiber reinforced articles is disclosed. The shaping means includes a first screen having a surface defining the contoured shape of the article; a second screen having a complementary surface defining the reverse contoured shape of the article; and, at least one resilient presser rod operatively attached to the first screen or the second screen. The presser rod engages the fiber matting and presses the fiber matting into either a portion of the first screen or the second screen as the screens are closed together. The shaping apparatus is particularly suitable for the manufacture of glass fiber-reinforced automobile bumpers.
