Abstract (en)

[origin: EP1905893A1] The machine has lower and upper fluted rollers (2, 3) for producing corrugations (44) in a paper web (43). A glue application device (13) applies a glue (49) to tips (45) of the corrugations. A pressing device (16) presses a lined web (46) against the tips, and includes an endless pressing belt guided over a deflection roller (17) and a cylindrical tension roller (18), where the tension roller is formed from a core and an outer jacket. The core and the outer jacket are separated from each other toward outer ends of the jacket and the core by an annular space.
