A machine for the manufacture of a single-face lined web of corrugated board (76), comprising
- a first and a second fluted roller (4, 13) for corrugating a paper web (72),
- a gluing device (24) for spreading glue on peaks (74) of the corrugations (73) of the corrugated paper web (72),
- a pressing device (31, 52') for pressing a liner web (75) on the Blue on the peaks (74), of the corrugated paper web (72) resting on the second fluted roller (13) along a contact area, the pressing device (31, 52') having a plurality of pressing belts pressable against the second fluted roller (13) along a pressing area,
- wherein each of the plurality of pressing belts is stationary and open-ended rather than continuous,
- wherein the plurality of pressing belts (33, 71) are adjacent and disposed one beside the other over a maximal width (d) of the corrugated paper web (76),
- wherein contiguous edges (78, 78') of the plurality of pressing belts (33, 71) take a course deviating from a conveying direction (77) of the web of corrugated board (76).
