PURPOSE:To prevent splash from falling on the bed by covering both the oversurface and sides in the region, where the cover confronts a support, covering flatly in regions where the cover does not confront supports, and by winding up each end of the regions named later. CONSTITUTION:A cover 3 is provided with an oversurface and sides supporting guide 4 in each region where the cover is fixed to the edge of a moving member (table) 1, i.e. where it confronts a supporting member (bed) 2, and thereby the oversurface and sides of the bed 2 shall be covered. In a region where the cover 3 does not confront the bed 2, a flat supporting guide 5 is furnished so that the cover 3 can be spread in a plane. The end of the cover 3 is wound up by a takeup machine 6. Thereby the bed 2 is covered thoroughly to assure perfect prevention of splash from falling on the bed 2. In the region off from over the bed 2, the cover can easily be coiled in flat condition, wherein any margin for movement of the cover is not required, which assures compacted construction. |
