Abstract
A method and apparatus are provided, for handling the backing film in a fiber placement process, by winding-up the backing film, into a roll, as the backing film is separated from a fiber tow. The backing film is wound-up in such a manner that it can be fed back out to rejoin the tow, should it be necessary to rewind a portion of the tow during the fiber placement process. The backing film may be wound onto a paper or cardboard core for ease of removal and handling.
