Abstract
Procedure and device for the manufacture of asbestos or similar cement pipes; in which an aqueous mixture, composed of fibers and a binder material, is continuously fed into a rotating molding core and wound on the latter, while a compression element presses against a surface, which moves synchronously with respect to at the circumferential speed of the molding core, at least, the fiber layer each time the maximum maximum against the layer of fibers below, characterized in that each new laid fiber layer and, at least, the fiber layer, disposed underneath it, they are treated with needles, that is, pierced.
