Abstract

A yarn winding apparatus is disclosed which is characterized by the ability to wind a plurality of running yarns onto a corresponding number of bobbins mounted on a common support spindle, and wherein the bobbins may be closely spaced apart to thereby permit the required length of the support spindle to be minimized. The apparatus comprises a plurality of side by side traversing assemblies extending along the length of the bobbin support spindle, with each traversing assembly comprising a yarn guide bar and a pair of oppositely rotating rotors. The rotors are each composed of two oppositely directed radial arms, which define two closely adjacent planes of rotation. The two rotors of each assembly are mounted for rotation about off-set axes, and such that the arms sweep across the guide bar in opposite directions to define the traverse stroke. Also, the two axes of all of the traversing assemblies are offset in the same direction, with the corresponding axes of all of the adjacent traversing assemblies being equally spaced apart a predetermined distance, and such that the extremities of the arms of adjacent traversing assemblies define circles upon rotation thereof which overlap in …
