Device and a method for applying a hardenable plastics coating in a tubular construction

Device for applying a coating of hardenable plastic to an inner side of a wall of a tubular construction, for example a sewage pipe, comprising:

• a supply chamber for containing a hardenable plastic,
• a delivery head comprising an outlet for letting out the hardenable plastic from the delivery head, and
• a pump for transporting the hardenable plastic from the supply chamber to the outlet,
• wherein the outlet is movable to various angular positions with respect to a rotation axis, for allowing the hardenable plastic to be let out of the delivery head at various angular positions with respect to the rotation axis,
• wherein the supply chamber comprises a flexible wall,
• wherein at least an element of the delivery head comprising the outlet is connectable to a drive unit for making the outlet perform a rotation movement in a first direction and/or in a second direction about a centre axis of the delivery head, the second direction being opposite to the first direction, wherein the device further comprises a rotatably arranged elongated element which at least partially extends inside the supply chamber, and which is arranged to connect the drive unit to at least an element of the delivery head comprising the outlet, for rotating the element.
