Abstract
A method for the production of an elastic laminate material web comprises laminating a cover material onto a carrier film consisting of a thermoplastic elastomer, using a hot-melt glue. The carrier film is rolled off a film roll and has a polymer powder on at least one side, to prevent interlocking of the layers of the carrier film in the film roll. The melt temperature of the powder is less than or equal to the gluing temperature of the hot-melt glue, so that the powder melts during lamination.
