Patent ID: 8043656

Claim:
A method for impregnating a lining module having a resin-absorbing layer and used for repairing a pipe, the method comprises the steps of: inserting at least one end portion of the lining module equipped with the resin-absorbing layer and an air-tight, outer coating into an air-tight sleeve; fixing an auxiliary introduction device on an introduction area of the lining module; air-tight closing transition areas between the lining module and the air-tight sleeve and between the introduction area and the auxiliary introduction device by means of at least one sealing device; air-tight closing of the auxiliary introduction device with respect to the ambient by providing a releasable blocking device such that a chamber formed by the air-tight sleeve, the auxiliary introduction device and also the lining module is closed in an air-tight manner and that an introduction chamber, accessible from an outside, is formed for filling with resin; evacuating air from the chamber such that a first pressure value is present within the chamber; introducing the resin into the introduction chamber, in which a second pressure value, different from the first pressure value, is present; and releasing the blocking device so that the resin is introduced from the introduction chamber into the chamber with an aid of a pressure differential between the first and the second pressure values thus resulting in the resin-absorbing layer of the lining module being impregnated with the resin.
