ABSTRACT:
Pile fabric is produced by needling in an ornamental pattern a pile layer of loose fibers through the back or nonvisible side of a fabric backing web which is intermittently passed with its back side up through a series of needling stations comprising needles disposed in a particular arrangement to form the fibers into the backing web in a predetermined pattern. A feed duct including a discharge port extending across the fabric web transversely of its feed direction is arranged to deliver fibers onto the back side of the web at a point upstream from the needling station. A suction duct located downstream from the needling station draws loose fibers from the back side of the web through an inlet port which extends across the web transversely of the feed direction. A driven roller located at the discharge port of the feed duct operates to distribute across the web the fibers being delivered thereon and a brush or shearing roller may be arranged downstream of the needling station near the inlet port of the suction duct to draw off loose fibers which have not been suitably needled into the backing web. A pile layer in a predetermined ornamental pattern which is visible from the front or lower side of the web may be formed by sequentially intermittently passing the web through a plurality of needling stations each of which comprises needles disposed to form a section of the overall pattern desired.
