Reusable high speed winding tube

DETAILED DESCRIPTION OF PREFERRED EMBODIMENT Turning now to the drawings, and particularly to FIG.
1, there is illustrated a yarn package of the type conventionally formed during the initial manufacture of synthetic yarn which exits from a spinneret.
As the spinning process has been improved, it now appears that yarn can be spun at speeds of 10,000-12,000 meters per minute.
To wind yarn being spun at such speeds on existing yarn tube sizes requires winding speeds in the range of approximately 30,000 R.

and above.
The ensuing description is directed toward a composite winding tube that will first of all withstand such winding speeds.
A second aspect of the present invention that will be described is the manner in which such tubes may be adapted for cleaning and reuse.
The yarn package includes a winding tube WT about which thousands of turns of yarn Y are wrapped.
The winding tube WT is formed of at least two parts, i.
e.
the cylindrical hollow tube 10 and at least one end cap 20.
A latching or starting groove extending around the periphery is formed between the hollow tube 10 and the releasable end cap 20.
As the yarn package is initially formed, a relatively small number of turns of the yarn are guided into the starting groove where they are locked and form the waste bunch WB.
The length of yarn extending between the waste bunch and the yarn package Y is referred to hereinafter as the transfer tail TT.
At the outset of the winding operation, an empty winding tube WT is initially emplaced on the spindle (not shown) of a winding machine ready to have yarn wound thereupon.
Rotation of the yarn tube is then commenced by some type of drive roll(s) which engage either one or both end portions of the winding tube, depending on the type of winding apparatus used.
At the outset of the automatic winding operation of polyester or any other extruded or spun synthetic yarn thereon, a vacuum hose is temporarily accepting the polyester or other polymeric yarn filament being extruded through the spinneret while awaiting the emplacement and start-up of the winding tube
