Abstract

A machine for the manufacture of tubes made of fiber cement or other material comprising an endless belt, at least a rotating cylindrical screen on which this band passes to collect a layer of the material, and an interchangeable mandrel with a cooperating anvil roller, the band bringing the material layer up to the gripping distance between the mandrel and the anvil roll to transfer the layer to the mandrel, characterized in that two loop forming rollers are provided, for application with the endless band, one on each side of the sieve or sieves, and are mounted to move as a whole and simultaneously together, so as to change the trajectory of the part of the band between them, and means are provided to imperatively move at least one of the forming rollers. loop.
