TISSUS NON TISSES, AINSI QUE PROCEDE ET APPAREIL POUR LES FABRIQUER

摘要

A non-woven continuous fabric comprises a plurality of discrete, laterally extending ribbon elements which are connected with continuous, longitudinally extending elements to form a netting which may be united with one or more layers of a continuous sheet plastics material orientated in the longitudinal direction of the fabric while at least the ribbon elements of the netting are also longitudinally orientated, i.e., in the lateral direction of the fabric. The fabric has been subjected to a needle punching operation causing the orientated materials thereof to fibrillate. A fiber fleece may be incorporated in the fabric. A method of producing the fabric comprises winding a continuous, longitudinally orientated ribbon of plastics material helically upon a plurality of thread- or ribbon-shaped secondary elements to form a netting which may be laid together with one or more sheets of longitudinally orientated plastics material to form a web assembly which subsequently is subjected to a needle punching operation. An apparatus for making the fabric comprises means for jointly feeding a netting and at least one sheet in superposed relationship and a needle punching device operating on the assembly of the netting and the sheet or sheets.
