Abstract
1,075,258. Lining pipes by extrusion. PIPE LININGS Inc. Dec. 8, 1965, No. 52015/65. Heading B5A. A pipe is externally lined with a mastic or cementitious material by being passed through an extrusion nozzle comprising two sectors 36, pivoted to swing outwardly against the actions of leaf springs 42, and a stationary sector 39. The invention is particularly intended for lining pipes having radially enlarged portions such as bell end pipes, Fig. 5 (not shown), since the nozzle can expand to accommodate such enlarged portions. The leaf springs 42 are adjusted for tension by set screws 50 and sectors 36 are pivoted as at (40), (41), Figs. 2 and 5 (not shown) and may have holes (51) to allow dehydration or deaeration of the moulding material. The pipe is fed to the extrusion nozzle by driven rollers (14), Fig. 1 (not shown), and beneath a hopper (17) containing a screw feed (18) is a further screw feed (30) driven by motor (27) through gearing (28), (29). In a modification, Fig. 6 (not shown), sectors (36A) and (39A) are provided with heating shoes (60) containing electrical resistances (62). Alternatively the heating may be by hot fluid circulation.
