ABSTRACT:
Apparatus and methods of using the apparatus to automate a labor intensive portion of the process of making continuous fiber products, like chopped glass fiber. In this process many fiberizers are used, each fiberizer forming as many as several thousand fibers. Fibers break frequently requiring the fiberizers to be restarted and this has always been a labor intensive part of the process. Apparatus for getting the fiberizers ready to restart quickly and for forming a fiber strand, apparatus for gripping the strand, breaking it and transporting it to strand pulling and processing equipment and apparatus for moving a newly started strand into a desired position on an optional strand separating and guiding means, and methods of using the apparatus are disclosed.
