ABSTRACT:
A machine for the production of a single-face lined web of corrugated board comprises a pressing device for pressing a liner web on a paper web provided with a corrugation. This pressing device comprises a vapor permeable pressing belt which consists of a fabric of metal with warp threads and weft threads. The warp threads arc provided in groups of three warp threads at a time, the distance of two neighboring groups of warp threads being smaller than the width of each group of warp threads. Preferably, the material of the weft threads is softer than the material of the warp threads, the weft threads having notches, in each of which a warp thread is disposed.
