Abstract: Elastic sheet for use as covering fabric consists of a plurality of interesting amorphorus threads produced from a molton mass of a synthetic polymer, the threads having a diameter of 0.1-1.5mm, and being placed in layers, and bonded together at the points of intersection. Specifically the sheet has a uniform structure and density, and all the surfaces are formed by projecting loops. The loops are disposed horizontally, or nearly horizontally on the lower face of the sheet to form a solid structure, while the density of the loop layers diminishes towards the upper face, the loops on the upper force of the sheet, may also be horizontal or nearly horizontal. The elastic sheet is produced by (a) extruding a molton mass of polyamide through orifices disposed at similar distances from each other, to form at least three staggered rows of the ends in the form of a hank, onto a coaling liquid, pref. water, the distance between the spinning die and the upper surface of the bath being 2-30cm. pref. 4-20cm. and (b) continuously withdrawing the formed sheet through the bath.
