Abstract (en)
1. Machine for externally coating with concrete tubular parts of revolution such as tubes (11), the said machine comprising at least two rotating supports (4, 5) adapted to support the part (11) at its end and drive it rotationally about itself, a storage hopper (6) for the concrete having an outlet orifice (9) which opens above the location provided for the part (11) and a lower wall (10) which extends above the said location and vibrating members (12, 13, 14) disposed in the outlet orifice (9) of the hopper (6) in the vicinity of the part (11) to be coated, characterized in that the supports are coaxial rotary drums (4, 5) displaceable along a common axis relative to each other, in that the said drums are disposed so as to penetrate inside the bore of the tubular part (11) to support it, in that the outlet orifice (9) of the hopper (6) is rearwardly offset from the vertical plane passing through the common axis of the drums (4, 5) taking into consideration the direction of rotation thereof, and in that the lower wall (10) of the hopper (6) is obliquely inclined above the location of the part (11) so as to delimit therewith a space having a transverse cross section in the shape of a wedge directed in the direction of rotation.
