ABSTRACT:
A method of needling a web comprises the steps of continuously supplying the web to needles, reciprocating the needles to stitch the web supplied to the needles and to release the stitched web, moving the released stitched web step by step by subjecting the released stitched web to a weight load, and then continuously withdrawing the released stitched web. An apparatus for carrying out this method comprises a dancing roller arranged to exert the weight load between a stitch base and means for continuously withdrawing the stitched web.
