PURPOSE:To economize personal expenses which is in its turn operation expense without requiring a great deal of man power for uniting of tubes, by performing the uniting of the tubes posterior to deformation of a cross-sectional form through automatic winding of a threadlike thing. CONSTITUTION:When a liner tube 1 is pulled away from a drum 2 through a through wire 8, the tube 1 passes through an application roll 4, to begin with, to the external circumferential surface of which an adhesive agent is applied, then the same passes through a folding roll 5 and turns into a state where the outside diameter is small by deforming a cross-sectional form. As a threadlike thin 7 is pulled out in a lateral direction from a reel 6 automatically according to a movement of the tube 1, wound round an external circumferential part of the tube 1 spirally and unites the tube 1 in a state that the outside diameter posterior to a deformation of a cross-sectional form is small, the tube 1 can be inserted easily into a pipe 3 by lasting pulling out of the tube 1. Along with expansion and restoration of the tube 1 to a state anterior to the deformation of the form by applying inner pressure to the tube 1 after insertion of the tube 1 into the pipe 3 the inside of the pipe 3 can be covered with the liner tube 1 by breaking the automatic winding threadlike thing 7. |
