Abstract: Method for unwinding web materials from two parent reels (1, 2), wherein a first parent reel (1) in a depletion phase is replaced by a second parent reel (2), wherein during said replacement a first and a second web material (N1, N2) are unwound from both parent reels, wherein before the completion of said replacement the first web material (N1) is joined to the second web material (N2) and then it is cut, wherein the joining of said web materials (N1, N2) is preceded by the insertion of the second web material in an area where the two web materials are joined, and during the step of inserting the second web material in said joining area the second web material is guided on a guide surface (41, 44) which guides it towards the joining area. In said insertion step, the second web material adheres pneumatically to guide surface.
