PROBLEM TO BE SOLVED: To form a sealing means continuously, automatically, and efficiently by a method in which a double-coated adhesive tape the surface of which is covered with a release tape and which is supplied to a bag body sealing opening part is cut and bonded to the opening part, the release tape is peeled off, a mold release tape of greater width than that of the adhesive tape is cut and bonded to the surface of the adhesive tape. SOLUTION: In an adhesive tape 9 made of a double-coated adhesive tape 11 the surface of which is covered with a release tape 10 and which is supplied intermittently, only the tape 11 is cut by a cutting blade 16, an adhesive tape piece 11a is bonded to the sealing opening piece constitution part of a bag body constitution material 1a by the reciprocating motion of a press member 14, and the tape 10 is peeled off. The material 1a having the piece 11a is sent to the next process, supported by a receiving base 21, and stopped. A mold release tape 22 of greater width than that of the tape 9 is held by a holding press member 24, pressed and bonded to the piece 11a by the reciprocating motion of the member 24. In this state, the tape 22 is cut by a separating blade 27. |
