发明名称 Method for producing velour needlefelt webs
摘要 The invention refers to a method for the production of velour needlefelt webs by processing a fiber fleece bonded through needling, using velour or fork needles forming pile loops. At least one fiber fleece band which consists of several layers is helically wound to form a tube which continuously develops in an axial direction. The tube rotates about its own axis, wherein the individual layers of the fleece band partly overlap on each wind and the lower or inner-lying layers of the wound tube are bonded in a width which is smaller, preferably up to half the width of the width of the fleece band in a known manner using felting needles and from the upper or outer-lying loose fiber layer of the wound tube, the fibers forming the pile loops are pushed through the pre-bonded lower or inner-lying fiber layer in a known manner using fork needles. The finished processed tube is cut open in the axial direction, said flat and the so-formed material web is wound up. sp This is a divisional of a previous application Ser. No. 06/108,041 filed Dec. 28, 1979, now U.S. Pat. No. 4,378,618 granted Apr. 5, 1983.
