Abstract

Abstract An apparatus and method for winding fiberglass filament about three axes of a substantially rectangular mandrel. 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.
