ABSTRACT:
Previous attempts to cut or trim a wet, non-woven, fibrous mat using a fluid jet have been largely unsuccessful, particularly when the mat contained reinforcing strands. The present invention overcomes this problem by using a fluid jet located below the mat in combination with a fluid jet set at an angle above the mat.
