摘要：A pressing assembly (10) and a method for forming a depression (105) within a
moving, wet gypsum board (100) is disclosed. The assembly comprises a pressing head(16) comprising a pressing surface which is arranged to contact the board, and a supportmember (17), the pressing head (16) being arranged to compress a portion of the boardbetween the pressing surface and the support member (17) to form a depression (105)within the board (100). The pressing surface comprises a first and second surface portion(24,25) separated by a relief portion (27), which is arranged to press the board (100)toward the support head (17) with less compressive force than the first and secondsurface portion (24,25). The assembly further comprises drive means (18,19,22) formoving the pressing head and the support member in a first direction which substantiallycorresponds with the direction of the moving board, and a second direction which issubstantially perpendicular to a plane of the board, while the speed of the pressingassembly in the first direction substantially matches the speed of the board.
