1. An apparatus for chopping continuous fibers into discrete fiber lengths comprising:
- at least one fixed head having a first side, a second side and at least one aperture therethrough;
at least one means for feeding at least one continuous fiber through the at least one aperture from the first side; and
at least one end mill on the second side of the at least one fixed head engaging the at least one continuous fiber.

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 through apertures in a fixed head. End mills engage the continuous fiber and chops them into discrete fiber lengths.

17. A process for chopping continuous fibers into discrete fiber lengths comprising the steps of:
-
providing at least one fixed head having a first side, a second side and at least one aperture therethrough;
at least one continuous fiber through the at least one aperture from the first side; and
rotating an end mill with a cutting end on the second side of the at least one fixed head wherein the cutting end of the end mill engages the at least one continuous fiber and chops the continuous fiber into discrete fiber lengths. - View Dependent Claims (18, 19, 20, 21, 22)
