Full Description:
BACKGROUND OF THE INVENTION 
       [0001]    The present invention relates to a laminated board, and more especially to a method for manufacturing laminated board and the apparatuses used on the same. 
         [0002]    In accordance with the conventional wooden laminated board, artificial stone laminated board, stone laminated board, fiberglass reinforced plastics and so on, they are widely used in decorating inner and outer of room, such as kitchens, bathrooms or wine bars and so on, among of them the description of a Chinese patent No.: 200310116851.4 reveals a method for manufacturing artificial stone laminated board, in which the stoke preparation is taken up on the worktable of the hydraulic press, such like stacking up the sheets of the laminated board on the worktable of the oil press, and pushing the oil press loaded with the stacked sheets of the laminated board into the inside of the vacuum cabinet along the track-way for vacuuming, and after releasing the oil press from the vacuum state into normal state the oil press kept in working state is pushed out from the vacuum cabinet, it will be kept in pressing state for 3˜4 hours so that the laminated board is completely solidified. Due to the carriages built on the both sides of the oil press, the stacking process will become inconvenient, and because the vacuum cabinet is used for vacuuming only and the oil press is used just for pressing, so only by pushing the oil press in or out the vacuum cabinet can the works be carried out, additionally the oil press is very heavy, so the operation is quite inconvenient as pushing in and out, and the operating efficiency is poor, additionally there is a big scale demand in the market, if there is only one oil press available, it signifies that the vacuum cabinet will be idle for 3˜4 hours in a cycle, so that this operating efficiency can not meet the requirement of the market, if increasing the number of the oil presses, the equipment investment will be increased, so how to decrease the manufacturing cost of the equipment, enlarge the production scale, fully take the advantage of the vacuum cabinet to carry out assembly line production, improve production efficiency and reduce cost are the issues expected to be solved.
