The present invention relates to an apparatus for forming a vertical film capable of covering the surroundings of a main hearth in an appropriate form. According to an embodiment the apparatus (1) for forming a film is regulated with the horizontal movement of an outer rim (31) by a supporting member (33). Therefore, the outer rim (31) is prevented from falling by being supported by the supporting member (33). Moreover, the rotation of the outer rim (31) can uniformize the thickness of the attachment along the entire circumference. Therefore, the frequency of maintenance can be drastically reduced. |
