Abstract

198,869. Hushes, A. Wilson-, and Commin, F. J. Dec. 28, 1922. No Patent granted (Sealing fee not paid). Moulding hollow-ware and pipes and tubes.- Tubes, boxes and cisterns are formed from sheets of compressible materials, such as pitch fibre composition, asbestos, cement, celluloses, and the like, by winding convolutions on a core or former until an article somewhat thicker than is desired in the finished condition is obtained, placing the article 5 on a mandrel 8 supported within the bore of an expansible double-walled chamber 7, contained within a mould 6, and inflating the chamber by pressure-fluid supplied at 9 until the article, is compressed to the finished thickness. The mandrel with the article 5 roughly formed to size may be inserted within the chamber 7 without removing the article from the mandrel. A longitudinally split metal covering 15 may be provided between the article 5 and the chamber 7. Specification 167,613, [Class 70, India-rubber &c.], is referred to.
