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.
