ABSTRACT:
A device for coating the internal surfaces of elongate hollow spaces includes a shield substantially corresponding to the cross section of the hollow space and capable of being displaced in the longitudinal direction of the hollow space by means of a bogie connected therewith. The shield is connected with supply ducts for a curable mass being in the plastic state. The supply ducts are provided with outlet openings substantially uniformly distributed about the periphery of the cross section of the hollow space. A blower is provided with a seat for a flexible tube capable of being pressed at the hollow space to be coated and substantially air-tight relative to the inner side and includes a supporting element capable of being stationarily anchored within the hollow space. The shield is provided with a central opening intended for the passage of the flexible tube containing a fiber material in addition to the impermeable layer. The supply ducts are connected with a distributing means for the curable mass carried by the bogie and terminate in pipes arranged about the external periphery of the shield. The outlet openings of the pipes substantially are formed by a cut led obliquely to the longitudinal axes of the pipes, terminating on the pipe enveloping lines next to the internal wall of the hollow space.
