Abstract 1,110,246. Needling apparatus. E. FEHRER. 24 Oct., 1966 [26 Nov., 1965], No. 47615/66. Heading D1R. Apparatus for needling hair or fibre webs of the type comprising a multiplicity of vertically reciprocable needles 4 passing through a perforated stripper 3 into a web 2 advanced on a perforated support 1 by pairs of rollers 10 and 11, 12 before and after the needles is characterised in that the feed rollers are uniformly driven and the upper roll 12 of the succeeding pair is of elliptical or oval crosssection and is driven independently of the associated lower roll 11 by the means for vertically reciprocating the needles e.g. crankshaft 9. The drive is such that the larger diameter of the roll 12 extends horizontally during needle penetration, and extends vertically during needle raising, thus effecting an intermittent feed on the web.
