Method of making retipped top-drive filling spindles

摘要

A top-drive filling spindle for use in the manufacture of textile yarn is provided wherein the tapered tip thereof is of a through hardened steel material that would more readily resist wear caused by the driving action of the quill disposed thereon. A top-drive filling spindle having wear on the tapered tip thereof can advantageously be retipped by grinding the worn tip to a predetermined size; applying a sleeve of through hardened steel or the like thereover; securing the sleeve thereon; and, finally grinding the thusly secured sleeve to the standard taper for top-drive filling spindles. With the application of the through hardened sleeve, it is anticipated that spindle wear would not occur for perhaps six to twelve years or more -- a two to three fold increase over the life of spindles currently used by those skilled in the art.
