Abstract
An apparatus for longitudinal splitting, in particular longitudinal slitting, of pipes laid underground and for the simultaneous trenchless pulling-in of a new pipeline comprises a carriage in the form of a frame, in which a cutting wheel for cutting open the pipe wall and a support roller, which serves as an abutment and is supported on the pipe wall, are arranged above one another. The carriage or frame has a base which engages in a form-fitting manner in a frame-like window of a pull and/or push linkage.
