Beschreibung
Zusammenfassung:	A unit for joining paper sheets together in corrugated board manufacturing equipment comprises at least one toothed or corrugated roll (1), which is mounted in such a way as to rotate about its axis; means (5, 6) for feeding and pressing at least one flat paper sheet (C2), which interact with the toothed or corrugated roll (1) in laying said flat sheet (C2) over the corrugated paper sheet (CO) conveyed by said toothed or corrugated roll (1) and gluing means (4) which apply adhesive on one of the sheets. According to the invention, the means for feeding/pressing the flat paper sheet (C2) against the corrugated paper sheet (CO) on the toothed or corrugated roll (1) consist of a roll (6) which is mounted in such a way as to rotate about its axis and parallel to the toothed or corrugated roll (1) and which is made, at least at its periphery (106) of a layer of natural or synthetic fibers or compacted blends thereof, having a certain compressibility and/or deformability.
