Claim:
A method for lining a pipe conduit or a duct by way of a sealing inner lining with a flexible tubing which consists of a coated fabric, knitted fabric, braiding, felt, non-woven or fleece, and which sticks to an inner wall of the pipe conduit or duct by way of adhesive, which comprises the steps: filling a metered quantity of an adhesive, under conditions in which a curing of the adhesive does not take place, into the flexible tubing with a uniform distribution over the flexible tubing length, introducing the flexible tubing into the pipe conduit or the duct, wherein one end of the flexible tubing is firmly held at the end of the pipe conduit or the duct, which is at the rear in a movement direction of the flexible tubing, and the flexible tubing is introduced into the pipe conduit or into the duct by way of pressure impingement whilst inverting, creation of conditions for the adhesive that, after inversion, is located on the outer side of the flexible tubing, in order to cure the adhesive in a short time, by way of irradiating by way of energy-containing waves, wherein at least one radiation unit is pulled through the introduced flexible tubing in the axial direction, and maintaining the inner pressure in the introduced flexible tubing, in order to press this onto the inner wall of the pipe conduit or the duct, until the adhesive between the flexible tubing and the inner wall of the pipe conduit or of the duct is cured, wherein after introducing the flexible tubing, a connection between the flexible tubing and a retaining strap running through the whole flexible tubing in its longitudinal direction, is separated at the end which is at the front in the movement direction of the flexible tubing, the separated-away end of the retaining strap is coupled outside the pipe conduit to the at least one radiation unit, the at least one radiation unit in a non-activated condition is pulled by way of the retaining strap through the flexible tubing up to its end which is at the rear in the movement direction, wherein a supply cable for the at least one radiation unit is pulled behind the at least one radiation unit over the complete length of the flexible tubing into this, and thereafter, the at least one radiation unit in an activated condition is pulled by way of the supply cable through the flexible tubing over its complete length.
