Abstract

965,579. Moulding wall plugs. RAWLPLUG CO. Ltd. Nov. 22, 1962 [Dec. 1, 1961], No. 43138/61. Heading B5A. [Also in Division F2] Wall plugs e.g. lined plugs, are made by forming tubes by passing strands 1 of jute, hemp or asbestos fibre through a tank 5 of blood albumen solution or a thermosetting plastics adhesive, then on to mandrels 3 and through dies 4, 6 into a dielectric heating oven 9 and between its pairs of electrodes 7 through further dies 8 of decreasing size, out of the oven to rollers 10 for advancing the tubes for severing. The apparatus may produce simultaneously plugs of different diameters at different speeds. The mandrels 3 may be hollow for the introduction of a plug lining of graphite powder or paste, or silicone wax lubricant or a leaden tube formed from a strip; they may also introduce a liquid component of a two-part thermosetting adhesive used for bonding the strands 1.
