Abstract: High speed traversing mechanism and method for winding filamentary material onto a rotating mandrel, wherein an indexer including a crank arm rotatable about a pivot point; a connecting rod connected to the crank arm at a second pivot point; a traverse guide connected to the connecting rod at a third pivot point located on the center line of the traverse guide and the traverse guide reciprocating within a support with rotation of the crank arm; the pivot point is positioned at a point on said center line spaced from the third pivot point; the connecting rod forming a given angle with the center line; the indexer means rotating the rotatable crank arm to displace the traverse guide along the center line within the support; and controlling the indexer to wind the filamentary material onto the mandrel.

Abstract: Winding method and apparatus for consecutively winding filamentary material (FM) on respective first and second mandrels, wheerein first and second independently operable spindles are mounted for rotation about respective parallel-spaced axes located in a horizontal plane of a winding apparatus frame; first and second mandrels are removably mounted respectively on each of the first and second spindles; a traverse mechanism mounted to the apparatus frame for movement between the parallel-spaced axes and for reciprocating movement along an axis parallel to, and spaced from, the parallel-spaced axes; independently rotating each of the first and second spindles; moving a traverse guide in cooperation with the independent rotation to consecutively wind FM on the first and second mandrels; transfer mechanism movably mounted to the apparatus frame for guiding FM from at least one of a first and second mandrel each having FM wound thereon to at least one of a second and first empty mandrel; and for each the first and
