Abstract

PURPOSE:To manufacture a covered tube with a high roundness economically and profitably by a method wherein a cloth-like body remaining only the neighborhood of the wind-up part uncoated is coated with water kneading substance composed mainly of hydraulic inorganic material, wound about the external circumference of a tube and rolled under pressure from the external circumference. CONSTITUTION:When a cloth-like body (such as cotton etc.) 2 which is coated with hydraulic kneading material 2b composed mainly of hydraulic inorganic material (such as plaster etc.) is wound on the external circumference of a tubular body (such as hard vinyl pipe etc.) 1 turning the coating surface of the cloth- like body inside, the wind-up part of the cloth-like body 2 is made up only of a cloth part 2a(e) which is not coated with water kneading material 2b. This covered tubular body is rotated about the axis, and by a compression means etc. such as an engagement with other push roller an off set is removed at a starting part 2b(s) of winding and an end part 2b(e) of winding is levelled to the part 2a(e) of the cloth-like body only and stretched. In this manner, a covered body B excellent in roundness is obtained.
