Abstract
A method and apparatus are disclosed for winding at least a layer of separate fibers or groups of fibers onto a rotating support while modifying the width of the layer by moving the layer between two extreme positions perpendicular to the direction of fiber travel and simultaneously moving each fiber or group of fibers in its own plane of motion, offset in relation to a vertical plane at an angle varying from one plane to the next.

An apparatus for producing a composite product of continuous fibers comprising:
- a mobile guide element for gathering said fibers in a form of at least a layer of fibers;
- a rotatable winding support onto which said layer is deposited;
- a distribution head comprising first and second plates and a plurality of non-parallel rods through which said fibers pass, said plurality of non-parallel rods extending between said first and second plates and forming a three-dimensional comb structure in which said rods are not in the same plane;
- and
- driving means to drive said mobile guide element in a direction perpendicular to said layer back and forth between two extreme positions as to vary the location at which said fibers pass through said plurality of non-parallel rods of said distribution head and thereby vary the spacing between said fibers upon leaving the distribution head.

- a rotatable winding support onto which said layer is wound;
- a distribution head comprising first and second plates and a plurality of rods through which said fibers pass, at least a portion of said fibers passing between differnet rods, said rods being non-parallel and extending between said plates and forming a three-dimensional comb structure in which said rods are not in the same plane;
- and
- driving means to drive said mobile guide element in a direction perpendicular to said layer back and forth between two extreme positions as to vary the location at which said fibers pass through said plurality of rods of said distriubtion head and thereby vary the spacing between said fibers upon leaving the distribution head.
