Five basic methods are employed where the filament feeding head is rotatable and reciprocative with respect to the mandrel and where the mandrel is rotatable and reciprocative with respect to the filament feeding head. Similarly, one of the elements can be rotated and the other thereof can be reciprocatable. The winding apparatus includes a supporting table and a series of clamps which are designed to automatically shift and rotate the mandrel to the second and third axis positions for winding about the three axes of the mandrel. A second embodiment of the apparatus employs mandrel tables located at 90* planes with respect to each other. The mandrel tables serve as supports and also as clamping members for changing the position of the mandrel. A plug-in programming mechanism is also provided for operating the apparatus on an automatic basis.

Claims (14)

1. Apparatus of the character described comprising frame means, mandrel supporting means carried by said frame means, means carried by said frame means for feeding a continuous filament under tension about a mandrel carried by said mandrel supporting means, and drive means carried by said frame means providing a rotating and reciprocating movement between said mandrel supporting means and said filament feeding means; said drive means including separate drive means for rotating and reciprocating movement operable independently of one another for control of the local thickness of the filament wound on the mandrel; said filament feeding means including a rotatable filament feeding arm having a feeding end axially offset from the axis of rotation thereof; said mandrel supporting means including a mandrel supporting table, means to move said table in a vErtical direction, a downwardly movable mandrel stabilizing member operable to engage the upper end of the mandrel, and opposed movable mandrel supporting means operable to engage opposite sides of the mandrel.
2. Apparatus defined in claim 1 wherein said mandrel supporting means includes a hydraulic cylinder providing the movement thereof.
3. Apparatus defined in claim 1 wherein said
3. apparatus defined means for supporting the opposite sides of the mandrel include flange plates rotatable about a horizontal axis slightly offset from the center of gravity of the mandrel thereby allowing the mandrel to rotate 90* about this axis due to gravitational effect.
4. Apparatus defined in claim 1 wherein said mandrel supporting table is rotatable about the vertical axis thereof independently of said table moving means.
5. Apparatus defined in claim 1 wherein said downwardly extending stabilizing member includes cam means providing a 90* rotation thereof.
6. Apparatus of the character described comprising a mandrel having the exterior thereof composed of planar surfaces defining at least two pairs of opposing sides, means for engagingly supporting the mandrel on each of two opposing sides thereof, a filament arm supported for rotation adjacent the periphery of the mandrel about an axis passing through one pair of opposing sides, said filament arm being arranged for reciprocation in the direction parallel to said axis of rotation as to wrap filament on the second pair of opposing sides; means for disengaging the mandrel from the engaging support means and rotating the mandrel with respect thereto as to present the second pair of opposing mandrel sides for engagement with the engaging support means whereby the filament arm is arranged to wrap filament on the first pair of opposing sides.
7. Apparatus as set forth in claim 6 wherein the means for rotating the mandrel with respect to the support means comprise means for engaging the mandrel at at least two points so displaced from the center of gravity of the mandrel as to cause the mandrel to rotate under the force of gravity until the second pair of opposing sides are adjacent the support means.
8. Apparatus as set forth in claim 6 wherein the first pair of opposed mandrel sides join the second pair of opposed mandrel sides at the edges of the sides as to define corners at each juncture of edges; said mandrel including means mounted at said corners for preventing the slipping of filament wound on the mandrel from the mandrel.
9. Apparatus as set forth in claim 7 wherein the filament slip preventing means comprise omnidirectional pegs mounted at the corners of said mandrel to extend outwardly therefrom.
