  • Apparatus for the repair of pipes
    Patent number: 4777905
    Abstract: A carriage (1) is guided coaxially to the axis (11) of a pipe (9) to be repaired by two sets (2, 3) of sprung rollers (4, 5). The carriage supports a drive motor (28), on the drive shaft (29, 30) of which is fixed a distributor means in the form of rollers (41). Coating material, for example a pressure setting plastic, is applied via a supply pipe (45) to the underside of the pipe wall (8) and is distributed by the turning rollers (41) over the circumference. In this way damaged sewer pipes can be correctly coated with small effort.
