ABSTRACT:
A method of impregnating the inner absorbent layer of a long flexible tube with a curable resin is begun by introducing a mass of the resin into one end of the tube. A window is formed in the impermeable outer layer of the tube at a distance from the resin mass. A vacuum in the interior of the tube is drawn through the window and concurrently the resin mass is pushed toward the evacuated region by passing the tube between a pair of squeezing members. When the flowing resin reaches the vicinity of the window, the window is sealed. Another window is formed in the tube farther downstream of the previously formed window. A vacuum is drawn through the new window while the squeezing members force the resin to flow toward the newly evacuated region. The procedure is repeated until the resin has spread through the entire inner absorbent layer of the tube.
