Abstract
An apparatus for the winding of continuous threads or yarns in which at least one chuck is provided, having a spool stop mounted thereon, on which at least one removable spool sleeve may be slidably positioned for thread take-up. The end surface of the spool sleeve has a lug formed on it which provides a defined spacing between the sleeve and stop when the sleeve is slid over the chuck. A means for cutting the continuous thread is located on the chuck in the space formed between the sleeve and stop. In the cutting operation, the thread is always presented to the cutting means at a constant, repeatable angle due to the action of the spool lug and a thread-catching notch formed on the end surface of the sleeve in a preferred embodiment of the invention. Furthermore, multiple spools may be mounted on the chuck in accordance with the teachings of the present invention in order to provide for increased efficiency of the winding operation.
