PURPOSE:To provide a titled device which permits the easy adjustment of the sealing part of a slight spacing and has good sealing performance by consisting the device of a semi-cylindrical sealing member provided to face a roller for conveying a sheet at the slight spacing therefrom and an elastic tongue-shaped sealing member in contact with the roller surface. CONSTITUTION:The semi-cylindrical sealing member 2 is provided to face the freely rotatably provided roller 11 apart at the slight spacing 11 therefrom in a manner so as to cover the upper half part of the roller and the sealing member 16 formed to the tongue shape of the flexible elastic body in contact with the axial direction of the roller 1 is provided to the surface of the roller 1 on the side opposite from the member 2. The roll type sealing device which conveys the sheet 6 by the above-mentioned roller and is delineated to a high-pressure side A and low-pressure side B is thus constituted. The sealing part of the spacing 11 is made easily adjustable by the above-mentioned constitution and the evacuation on the low-pressure side B is easily made possible with the spacing 11 at only one place and therefore the sealing performance is improved. |
