The fibres may be of carbon, glass, aluminium oxide, zirconium oxide, asbestos, boron, copper or steel, or polyester, polyacrylonitrile, polytetrafluorothylene, a copolymer of tetrafluorotheylene and hexafluoropropylene, polyamide fibres e.g. wholly aromatic polyamide, or polyamide-imide fibres e.g. of the polytrimellamide-imide type. The polymeric binder may be present in the fabric either in the form of a pre-polymer or a completely cross-linked resin. The web may be formed by dry or wet laying techniques. The polymeric binder can be incorporated in the form of a powder or aqueous solution or dispersion before or after web formation. In a typical example, a polyimide prepolymer, obtained by heating a mixture of N, N'-4, 4'-diphenylmethane-bis-maleimide and bis(4-aminophenyl)methane, is mixed with aromatic polyamide fibres in water and a web is formed from the dispersion using a paper-making machine. The non-woven fabrics may be used for making filters, catalyst supports, and cores for electrical insulating linings.

Pattern control is effected in a tufting machine by scanning a pattern by photo-electric means, converting the resulting signals into information bits which are stored in a magnetic memory, and subsequently employing the stored information to control the pattern-producing mechanism of the machine. As shown, a rotary drum. 1, containing a lamp 21, carries a pattern 2 scanned by a photo-cell 6 traversed axially of drum 1 by a rotary screw 23. Circumferential dots 3, equal in number to the number of tufting neodles, are scanned by a photo-cell 7. A single dot 4 is scanned by a photocell 8. Photo-cells 6, 7 and 8 are connected via the contacts 9, 25 and 24 respectively of a changeover switch to a magnetic storage 16 of the matrix type, photo-cells 7 and 8 connected via an impulse-producing device 17. Information bits for controlling the supply of yarn to the row of needles are thereby stored in matrix 16 at each revolution of drum 1. On completion of the scanning of pattern 2, the contacts 9, 24, 25 are changed over and the tufting machine is operated, whereby, at each descent of the needle bar, an impulse is applied to device 17 for effecting the scanning of a row of bits in matrix 16. The result of each such scan is transferred to a register 18, the output leads 20 of which are connected to brake solenoids adapted to control the pressure on the yarn fed to the respective needles for producing either long or short tufts. It is stated that the magnetic memory may alternatively be a magnetic tape.
