ABSTRACT:
A filamentary gathering apparatus, apparatus for forming filaments into a gathered bundle of filaments, and a method of forming gathered filaments into a bundle of filaments according to the present invention result in a reduced tendency of the filaments and/or gathered filaments to wrap around the gathering apparatus. The gathering apparatus is a cylindrically shaped gathering shoe having a height much smaller than the diameter of the shoe and having an annular recess providing for a peripheral groove in the shoe. The groove has a plurality of holes extending radially toward the center of the gathering shoe and up the side of the groove. The apparatus for forming filaments has a fiber forming means, an applicator, one or more rotating gathering shoes and a winder mechanism. The one or more rotatable gathering shoes have the groove with radially extending holes. The method of forming the bundle of filaments from a heat softenable, fiberizable material includes forming the filaments, applying a chemical treatment to the filaments, gathering the filaments into one or more strands by using one or more gathering shoes having the groove with radially extending holes and winding the one or more strands into a package.
