Abstract
The invention refers to a machine for the production of velour needlefelt webs through processing a fiber fleece bonded through needling, using velour or fork needles forming pile loops, wherein at least one fiber fleece band consisting of several layers is helically wound to form a tube continuously developing in axial direction, said tube rotating 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 and wherein the finished processed tube is cut open in axial direction, laid flat and the so-formed material web wound up.
