A nozzle exit cone is also disclosed made from such transverse tape so that the fiber strand portions are short enough that they do not follow the curvature of the nozzle and thereby peel. The windings are shingled onto the nozzle exit cone so that only one end of each of the fiber strand portions is exposed to the nozzle surface. The fiber strand portions are oriented at a predetermined angle which may be optimized for erosion resistance and stress requirements.

Abstract: Wire arrays (11) having a continuous wire (12) which is formed into a predetermined pattern and adhered to a backing material or substrate (13) are fabricated by applying adhesive material (16a, 16b) along opposite edge portions (17, 18) of the substrate, positioning a row of winding spools (21) along each of the edge portions and repeatedly extending the wire between and around successive spools at the opposite edge portions. The wound wire is then traveled along each spool toward the substrate and into contact with the adhesive. The spools are then removed and a coating of hardenable material (54) is applied to secure the wound wire to the substrate. Tension in the wire is relieved prior to contact of the wire with the adhesive and a small amount of slack is introduced into the wire before the final coating step. Mechanism (32) is provided for lifting the spools away from the substrate without disturbing the wound wire.

Abstract: Tape or patch material for making joints which have good tensile strength includes a reinforcing array of yarns arranged within a narrow range of angles around the direction of application of probable stress on the joint. The distribution of yarns angles within a small range rather than exactly parallel to each other gives the joint greater splitting resistance with very little loss in strength, and it permits toleration of less precise alignment of tape when the joint is made.The patch material is particularly useful for joining coated abrasives into endless belts. For such joints, it has long been known that better results are achieved if the joint makes an angle other than perpendicular with the edges of the belt.

Abstract: A method and an apparatus are described for making a filamentary web. One or more strands of roving, each composed of multiple filaments, are spread out to increasing extents until the filaments form a band in which they extend unidirectionally and generally parallel to each other, but are not connected with one another. Adhesive strips, threads or other connecting elements are then transported on a carrier into a working station so as to be positioned transverse to the elongation of the band. In the working station, they are transferred to the band and joined to the filaments under application of contact pressure in the nip between cooperating nip rollers. This converts the band into a unitary filamentary web structure in which the filaments are all unidirectionally oriented.

The composite web of materials is drawn to an oven where it is shaped and cured to produce the finished composite member. The finished member has a center ply of unidirectional filaments which is encapsulated by upper and lower transverse layers of unidirectional filaments. The transverse layers retain the shape of the unidirectional filaments, adding to the strength of the finished member.

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.
