  • Patent number: 4487646
    Abstract: An optic fibre is wound around a drum and a strip of flexible adhesive is plied across the width of the winding to maintain the relative positions of individual turns of the winding. The fibre turns and adhesive are then cut across the width of the winding and the resultant ribbon is unwrapped from the drum. One end face of the adhesive in which the cut ends of the fibres are secured is then cut such that the axes of the fibres assume a predetermined orientation relative to the cut end face. The cut end face is then applied against the surface of a former of predetermined shape and the fibre ends are secured in the positions they have assumed. A radial fibre arrangement is obtained by cutting the end face normal to the fibres and using a cylindrical former.
