Abstract
Procedure to form a non-woven cloth (6) made of synthetic filaments (5) in which synthetic filaments (5) are extruded, stretched, cooled, and projected onto a moving plastic fabric (1), which is characterized by cleaning the plastic fabric (1) by passing a hot liquid fluid at high speed over the point t.sub.2 of the filaments (5) and the melting point t.sub.1 of the fabric (1), the melting point of the latter being at least 80.degree. C. above that of the filaments (5). As an example, the fabric can be of polyetheretherketone yarns or of polyphenylene sulfide yarns. Easy installation of the fabric and possibility to clean it and therefore increase its life.
