Abstract: The present invention relates an improved creel adaptor for use in retaining a forming tube containing formed glass fiber during the twist process. The improved creel adaptor is designed to maintain a forward outside diameter slightly smaller than the rear outside diameter, wherein the forming tube is placed on the creel adaptor and maintained in position by the variation in the outside diameter of the creel adaptor.

Abstract: The disclosure embraces a method of and apparatus for transferring dual strands or bundles of filamentary material from a rotating single supply package or creel package onto bobbins mounted on first and second rotating spindles, the method and apparatus involving the use of a control unit, stop motion assembly or knockoff device for each strand or bundle, the control units, stop motion assemblies or knockoff devices having a mechanical interconnection established whenever one of the strands or bundles breaks or sustains loss of tension whereby the rotation of the supply package and the rotation of the two spindles mounting strand or bundle receiving bobbins are interrupted.
