Abstract
A method and an apparatus impregnate a lining module for repairing a pipe. An end area of the lining module provided with a resin-absorbing layer and an air-tight, outer coating, is introduced into an air-tight sleeve, and an auxiliary introduction device is fixed at an introduction area of the lining module. The transitions between the lining module and the sleeve and between the introduction area and the auxiliary introduction device are closed off in an air-tight manner by at least one sealing device. The auxiliary introduction device is closed off with respect to the ambient by a releasable blocking device in an air-tight manner in such a way that the chamber, formed by the sleeve and the auxiliary introduction device and optionally also the lining module, is closed in an air-tight manner and an introduction chamber accessible from the outside is provided for filling with resin.
