Abstract
In the method for placing a plastic tube having a predetermined inherent stiffness into existing openings or through-passages a hardenable material, usually a hardenable synthetic resin, is applied onto the wall of the tube before placing the latter into the opening or through-passage. This hardenable material hardens completely only after a certain time period, i.e. after the tube has been brought into its desired position, to thereby increase the original inherent stiffness of the plastic tube. The device for carrying out the method includes apparatus for applying the stiffening material onto the wall surface of the tube.
