1. An apparatus for chopping continuous fibers into discrete fiber lengths comprising:
- at least one vibrating table supporting a fixed cutting blade;
at least one vibrator head engaging the vibrating table to cause said table to move in a reciprocating movement;
a flexible means for flexibly supporting the vibrating table;
said blade cutting in the same direction as the movement of said table; and

Abstract
This fiber chopper overcomes the disadvantages of the previous cutting rollers for chopping continuous filaments. The apparatus includes a means for feeding continuous fibers to a vibrating cutting blade. The vibrating blades engage the continuous fiber and chops them into discrete fiber lengths. A vibrating head vibrates the cutting blades through a vibrating table.
