Abstract

A method of processing glass filaments includes providing a length of glass filaments from which a portion is to be separated from the remainder of the filaments; directing energy to the filaments so as to cause a reduction in the width of the filaments at a desired location for separation of the portion; and causing relative longitudinal movement between the portion and the remainder of the filaments to separate the portion from the remainder of the filaments at the desired location.
