FIELD: textile fabrics, paper.
SUBSTANCE: invention is related to the field of spiral two-dimensional fibrous cloth manufacture. Crosscut fibrous cloth is formed by overlapping and directed substantially in radial direction in reciprocal manner along trajectory between external and internal peripheral edges of cloth with turn of crosscut cloth at every end of mentioned trajectory, at that width of crosscut cloth reduces from its external peripheral edge to internal peripheral edge, and crosscut cloth is retained in process of its formation. In order to form spiral longitudinal cloth, surface density of which reduces from its external edge to its internal edge, threads or plaits (204) are supplied that are substantially parallel to each other. Crosscut cloth and spiral longitudinal cloth are overlapped, continuously moved in rotary manner in plane and joined to form spiral two-dimensional cloth, which is later withdrawn.
EFFECT: simplification of method and reduction of expenses for manufacture of spiral two-dimensional fibrous cloth, and also reduction of material density and thickness non-uniformity.
