摘要： PROBLEM TO BE SOLVED: To make it possible to prevent the upper surface of a preliminarily compressed mat from becoming rough. SOLUTION: The method for manufacturing a woody cement plate has the steps of sandwiching a mat 3 between the upper and lower surface plates of a preliminarily compressing unit 5 to preliminarily compress the mat 3 to reduce the mat 3 in thickness, stacking the thinned mats 3 in multi-stage, once compressing it by a press 7, and curing the mat 3 of the multi-stage held in the compressed state in a curing chamber 8, and comprises the steps of superposing in several stages and preliminarily compressing it. The method further comprises the steps of enclosing the upper and lower plates of the unit 5, preliminarily compressing the mat 3, and then once stopping the upper and lower plates on the way of opening them. Further, the method comprises the steps of retaining both the ends of the film at both ends of the upper plate of the unit 5, suspending the film from the lower side of the upper plate, and preliminarily compressing the mat 3 via the film.

摘要： PURPOSE: To obtain an inorg. panel uniform in thickness and density by inclining the shaft of a brushing roll brushing the surface of the inorg. panel raw material mat arranged on a feed plate in a feed direction. CONSTITUTION: The shafts A of brushing rolls 14A, 14B are inclined at an angle θ smaller than 90 deg. in the feed direction shown by an arrow. Therefore, the raw material 12A of the surface part of a mat 12 is scraped toward the both side parts of the mat 12 as shown by an arrow by the reverse rotatory powers of the brushing rolls 14A, 14B. As a result, the density of both side parts of the mat 12 becomes larger than that of the central part thereof. When the mat 12 thus shaped is compressed, push-out force is exerted on both side parts of the mat 12 laterally but both side parts are hard to be pushed out because larger than the central part in compression rate, that is, density and, even if both side parts are slightly pushed out, the thickness and density of both side parts become almost same to those of the central part.
