Title:
A pressurizer and a method for forming a dent in the gypsum board which moves
Document Type and Number:
Japanese Patent JP6139556
Kind Code:
B2
Abstract:
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 support member (17), the pressing head (16) being arranged to compress a portion of the board between 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 second surface portion (24, 25). The assembly further comprises drive means (18, 19, 22) for moving the pressing head (16) and the support member (17) in a first direction which substantially corresponds with the direction of the moving board (100), and a second direction which is substantially perpendicular to a plane of the board (100), while the speed of the pressing assembly in the first direction substantially matches the speed of the board.
