Verfahren und Vorrichtung für die Herstellung von Textilvlies.

摘要

The invention relates to the manufacture of nonwoven textiles by needle-punching, using a card (1) with comb (2), a web-spreader (6) which deposits the web of textile fibres, and one or more needling devices. …Means are provided by which the weight per unit area of the web supplied by the card (1) is constantly changed according to a periodic pattern by varying the speed of the exit comb (2), so as to achieve, at the exit of the superposition machine (6), a web wherein the weight per surface area varies over its width, so as to counteract the non- uniformities in the distribution of the weight per unit area caused by the needling devices or consolidation machinery. ……
