Device for production of a corrugated board with at least one side being covered

摘要

The machine has two ripple rollers (4,13) for producing ripples (73) on a paper board (72). A glue applicator (24) applicates glue on the peaks (74) of the ripples and a pressing device presses a board (75) onto the glued peaks. The machine's pressure unit has at least one stationary endless pressure belt (33), and may have several belts next to each other over the maximum width (d) of the paperboard web (76). A separate tensioning device (35) is allocated to each pressure belt, and the belts are mounted on a common holder. The tensioning device is formed by a linear actuator engaging with one end of the respective pressure belt.
