PURPOSE: A production method of a multilayered gasket for sealing is provided to flatten a rubber mixed agent layer into a thickness that a user desires by consequentially conducting coating and drying in a time sequence. CONSTITUTION: A production method of a multilayered gasket for sealing includes the following steps. A rubber mixed agent is formed mixing a rubber mixture with a toluene solution (s10). A rubber mixed agent is coated on a surface of the fabric paper which is inserted to be cross linked between a first roller, a second roller, and a third roller by injecting the rubber mixture agent from an upper part of the first roller while the fabric paper is inserted into a space between the first roller and the second roller (s20). The fabric paper, on which the rubber mixture agent is coated, is calendared being inserted in between calendar rollers which are separated with a zigzag path with a predetermined interval (s30). The calendared fabric paper is formed in a solid bottom by laminating and compressing (s40). The integrated fabric paper is cut into a predetermined shape and perforated (s50).
