Abstract
1287063 Needling apparatus BUNZL & BIACH AG 6 April 1970 [4 April 1969] 16121/ 70 Heading D1R Non-woven fabrics are perforated by needles whose cross-section increases continuously from tip to base without change of shape whilst a current of gas is blown along the surface of the needles in the opposite direction to the penetration, to prevent the needles tearing fibres from the fabric. The fabric 5 may be passed by belts 10 between a perforating roller 1 and a hollow roller 3a. A partial cover 11 directs compressed air introduced through pipe 7a towards the fabric. The compressed air may be heated, and roller 1 may be hollow, and supplied with warm fluid by pipe 12. The perforated roller may be replaced by a perforated belt (3, Fig. 1, not shown); air is directed against the lower surface of the belt by nozzle (16). Conical, pyramidal and starpyramidal needles are illustrated (Fig. 3, not shown). The fabric may be moistened before the perforation by heated rollers, to achieve an ironing effect. The fabric may be bonded with adhesive, preferably after perforation.
