PROBLEM TO BE SOLVED: To provide a jig for joining natural casings, capable of being used in adhesion joining ends of casings C1, C2 in a state that the ends are mutually overlapped outside and inside, when blanks 1, 2 are given by attaching the casings C1, C2 to hollow holding tubes 3, 4, respectively, so that the casings engage each with the holding tubes from the outside and are subjected to the joining. SOLUTION: This jig for joining the natural casings has a base frame 8, a support rod 9, an elastmeric film 10, and a coupler 17, wherein the support rod 9 is supported by the base frame 8 and supports both the blanks 1, 2 on its surface in a state that the blanks are adjacent to each other, the elastmeric film 10 which is expandable and deformable is positioned at an intermediate area of the surface of the support rod 9, and the coupler 17 is positioned at one of both ends of the support rod 9. The elastmeric film 10 is expanded and deformed in a state that the ends of the casings C1, C2 of both the blanks 1, 2 supported on the support rod 9 are mutually overlapped outside and inside, so that overlapped parts of both the casings C1, C2 are made to be adhered and fastened to each other. A check valve 16 for preventing a back flow of compressed air is built in the coupler 17. COPYRIGHT: (C)2003,JPO
