Abstract
This invention relates generally to a shuttle spring for holding a yarn filled bobbin in a loom shuttle wherein the spring has a pair of opposed jaw portions for resiliently holding the bobbin therebetween. A vertical side surface of one of the jaw portions has a greater vertical width than the vertical side surface of the opposing jaw portion to effect rotation of the bobbin, when being ejected from the shuttle by the insertion of a full bobbin, in a direction so as to ensure that an adequate transfer tail of unused yarn separates from the spent bobbin. The transfer tail of yarn trailing from the bobbin is then caught by a stripping machine which completely strips the bobbin of the unused yarn.
