Abstract: Apparatus for cooperatively moving a plurality of guides for continuous filaments relative to spools upon which they are being wound to insure winding in even, successive layers. Spindles carrying the spools are mounted in parallel arrangement in a plurality of horizontal rows. A single, ball bearing screw is mounted with its axis vertical and carries a traveling member connected to an articulated arm. A linkage arrangement transmits reciprocating motion from the traveling member, through the arm, to a plurality of shafts, each carrying a guide element arranged adjacent one of the spools. The individual threads each pass over one of the guide elements to be moved thereby back and forth along the spool while being wound thereon. A selectively positionable switch arrangement allows adjustment of the limits of travel of the linkage, and thus of the guide elements. Means for adjustably positioning pairs of coaxial guide-carrying shafts are also disclosed, thereby doubling the capacity of the apparatus.
