Process for forming a nonwoven fleece (6) of synthetic filaments (5), in which the synthetic filaments (5) are extruded, stretched, cooled and applied to a moving plastic cloth (1), characterised in that the plastic cloth (1) is cleaned by passing through it a hot fluid at high speed which has a temperature of between the melting temperature t2 of the filaments (5) and the melting temperature t1 of the cloth (1) which is higher than that of the filaments (5) by at least 80 DEG C. …<??>The cloth can consist, for example, of yarns of polyether ether ketone or yarns of polyphenylene sulphide. …<??>The cloth is easy to fit and there is the possibility of cleaning it and therefore increasing its lifetime. …<IMAGE>… |
