ABSTRACT:
A device and method for rehabilitating pipe connections is disclosed that simplifies the reliable transportation and positioning of a pipe lining relative to a junction region of a building service line to be lined. The device and method provides for rehabilitating the junction of a building connection from a main pipeline into the building service line. With a positioning mechanism, a curable pipe lining may be positioned at the junction of the building service line from the main line and, with a transport mechanism, the positioning mechanism and the pipe lining may be transported to the junction. An alignment body may be arranged so that it may move the transport mechanism and which can be moved into the junction of the building service line. A drive may move the alignment body into the junction of the building service line.
