IMPROVED NON-WOVEN FABRIC

摘要

Method and apparatus for the production of a stitch-bonded fabric in which the stitches are locked by the formation of tufts or loops of fiber which are interlocked into the stitches of thread produced by the reciprocation of a series of tubular or slide needles. The invention also provides timing of the movements of the slide or tubular needles relative to the movements of the closing wires or rods for these needles and to the control of the distance moved by the needles and the closing wires or rods so that the wires or rods do not penetrate the fibrous batt completely and the degree of penetration of the needles is controlled to prevent the creation of voids in the batt which will prevent the formation of fiber loops when the needles are retracted to form stitches.
