| description | The invention provides a production method of a lining hose for trenchless pipeline repair, and relates to the field of lining hoses for pipeline repair, the lining hose comprises a cylindrical hose body and an inner container layer arranged in the hose body, the lining hose comprises the hose body and the inner container layer arranged in the hose body which are bonded in a split mode, and the inner container layer is arranged in the inner container layer. The liner layer is locally folded along the axial direction to form a wrinkle part, and is unfolded in the outward turning construction, so that the thickness of the liner layer is prevented from being changed due to the bearing tension; according to the production method, the strip-shaped base material is rolled into the cylinder shape, the inner sealing strip and the outer sealing strip are arranged on the inner side and the outer side of the opening strip seam of the base material in a heat sealing mode, the production efficiency is high, the sealing ef |
