Abstract
121,137. Warren, W. P. Sept. 12, 1916. Moulding pipes and tubes.-In the manufacture of pipes and tubes from cementitious material in sheet form having textile fabric embedded therein, the fabric is embedded in the cementitious material in such a way that a portion of the fabric is left projecting at one or both edges, so that after the sheet has been subjected to the necessary pressure to form a stiff paste or dough in sheet form, it may be lapped round a core or mandrel and the edges brought together and the projecting edges of the fabric embedded in the cementitious material and the joint smoothed off. The fabric may be made of jute, hemp, asbestos, hair, &c., and the cementitious material may consist of a mixture of Portland cement and asbestos or jute fibre.
