Abstract
The invention relates to a device for producing weft webs consisting of parallel spaced threads, in which at least one weft thread is fed around positioning, holding and advancing elements which consist of continuous endless belts which support a plurality of juxtaposed blocks which have a length corresponding substantially to the desired spacing between two consecutive weft threads. The blocks are in contact with one another in the rectilinear portions of the endless belt and spaced in the curved portion as they pass around drive rollers. At least one reciprocating thread guide has a free end which passes between the blocks in the curved portion of each endless belt, to feed thread between the blocks.
