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.
Claims9
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
- at least one fixed head having a cutting surface spaced apart from said table in the same direction as said reciprocating movement wherein the continuous fiber to be chopped passes between the cutting blade and the cutting surface.
