ABSTRACT:
The present invention is directed to a method and apparatus for forming a tailing end of predetermined length and the resultant package formed thereby. The tailing device includes a conically shaped hub positioned on the outboard end of a drive roll and provided with a spiral groove in the outer surface. The groove runs from a terminal flat circular groove upwardly to the main cylindrical drive portion of the roll. Means are provided for moving a strand sequentially into contact with the flat circular groove to form a bunch on the package support and thereafter in contact with the spiral groove so as to print helically wound wraps of strand about the support prior to the initiation of winding the main body of strand on the package as by conventional traverse means. The width and number of turns the spiral groove makes along the extent of the hub regulates the length of usable tailing end that will be formed in the completed package. The formation of the tailing end is accomplished by positive mechanical means which are independent of changes in winding speed or tension and accordingly is able to repeatedly produce tailing ends of essentially equal length from package to package.
