Abstract of the Disclosure 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 con- nected 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.
