The guide member is pivotally attached to the side plate via the elastic body so as to be rotatable and returnable, with a feeding gap between it and the tip of the holding member capable of holding and feeding the peeling tape. At the same time, the leading end of the guiding member is made to protrude from the leading end of the holding member so that the pressing piece can come into contact with it, and faces the guiding groove, and the members to be bound to be inserted into the guiding groove are shaped. A cutter is located below the feed wheel, and when engaged with an actuating piece facing the guide groove, cuts the adhesive tape to which a peeling tape is superimposed, with a blade connected to the actuating piece. A reel wound with adhesive tape and a reel wound with peeling tape, which are pivotally attached to the side plate via an elastic body so as to be rotatable and returnable, hook the tape to the feed wheel and the guiding member, respectively. Since it is rotatably attached to the side plate, it has a simple structure, can be manufactured at low cost, and operates reliably.In order to open a bag or other object to be bound, a peeling tape must be attached. The bag can be easily opened by thinning both ends of the adhesive binding tape outward and peeling off the adhesive tape, and there is no need to tear the bag as in the past, so the bag can be reused. There are also economic effects.

The leading end of the guiding member is slightly protruded toward the introduction guide groove side from the leading end of the holding member so as to be able to come into contact with the pressing piece.
As a result, the adhesive tape that binds the opening of the members to be bound and the peeling tape are pressed against the tip of the pressing member using the pressing piece and the opening, thereby ensuring and strengthening the adhesion of both tapes. This eliminates the need for blank firing even during the first operation, and the cutter blade is installed below the feed wheel so that it can penetrate to strengthen the adhesion of both tapes. Wearing will be more secure.

The presser member has its curved concave surface in contact with the peripheral surface of the feed wheel, and a peeling tape is provided between the tip of the guide member so that it can be sent out, and the tip of the presser member has a thin shape. Therefore, the peeling tape is regulated to a predetermined length and polymerized and adhered to the adhesive tape, and since there is no step between the holding member and the guiding member, both tapes are pressed by the member to be bound and the guiding member. to ensure polymerization and adhesion.
