Abstract: A highly absorbent and fragile composite sheet normally used as a throwaway domestic wiper is quickly and easily converted to a strong and attractive colored wallcovering. Thus, a composite layer comprising a net material sandwiched between and bonded to a pair of cellulosic-fleece (wadding) layers has a carrier sheet of paper bonded thereto, has colorant applied thereto, and is impregnated with a synthetic resinous bonding medium so that the fleece layers are bonded together at the mesh openings of the net material. In a preferred construction, the carrier sheet of paper has an internal cohesion inferior to that of the composite layer so that with the covering on the wall the composite layer is peelable from the carrier sheet adhering to the wall.

Abstract: The present invention relates to a method of and apparatus for manufacturing a net of non-woven threads, in which first and second laps of parallel threads, are drawn off, respectively, from a fixed creel and a rotary creel with the first lap longitudinal and the second lap transverse and wound about the first lap. The threads of the second laps are severed at each of two opposed longitudinal edges of the first lap and the net formed by part at least of the longitudinal threads of the first lap and those pieces of the transverse threads of the second lap which are situated on one and the same side of the first lap is collected and stabilized, while there is effected relative running ahead of the longitudinal threads which increases progressively from one thread to the next in relation to one of said edges, from the latter up to the other edge.
