ABSTRACT:
A method and apparatus are provided for substantially containing dust generated along a fiber tow path extending from a creel to a compression roller in an automated fiber placement machine, by enclosing substantially all of the path of the fiber tows between the creel and the compression roller within a barrier that is substantially impermeable to dust. A dust collection apparatus may have a porous media and/or utilize an electrostatic charge for entrapping the dust.
