Abstract

Zur Herstellung einer Matte aus Endlosfäden oder Schnittfasern oder dergleichen werden senkrecht gegen die Ebene eines aus diesen Werkstoffteilchen gebildeten Geleges Fluidstrahlen gerichtet, welche in gleichmäßiger Verteilung reihenweise punktförmig auf das Gelege auftreffen. Mit der Transportgeschwindigkeit des Geleges werden die Fluidstrahlen so verschwenkt, daß zwischen ihren Auftreff­ punkten und dem Gelege keine Relativbewegung entsteht. To make a mat out of filaments or Cut fibers or the like are perpendicular against the Level of a scrim formed from these material particles Fluid jets directed, which are evenly distributed Strike the fabric in rows. With the The transport speed of the clutch will be the Fluid jets pivoted so that between their impingement score and there is no relative movement of the clutch.

Zur Durchführung dieses Verfahrens dienen zwei angetriebene Walzen (11, 15), von denen mindestens eine auf einer Hohl­ achse (10) drehbar gelagert und mit radialen Boh­ rungen (14a, 14b) versehen ist, die in gleichmäßiger Verteilung über den Walzenumfang angeordnet sind. Die Walzen (11, 15) sind mit Profilen (18 bzw. 16) versehen, über die sie ineinander eingreifen und im Eingriffsbereich Kammern (19) bilden, worin die Bohrungen (14a und 14b) münden und die darin gehaltenen Werkstoffteilchen intensiv verwirbeln Two driven are used to carry out this method Rollers (11, 15), at least one of which is on a hollow axis (10) rotatably and with radial Boh stanchions (14a, 14b) is provided in uniform Distribution are arranged over the circumference of the roller. The Rollers (11, 15) are provided with profiles (18 and 16), through which they interlock and in the area of engagement Form chambers (19), in which the bores (14a and 14b) flow out and the material particles held therein intensely swirl
