PURPOSE: To manufacture a connection member of a multi-layer structure to be used for a filter bag for removing dust of a plate or a straw board. CONSTITUTION: A main body 7 of a connection member 4 has an aperture part 5 corresponding to a dust entrance to a filter bag. A gate slide 6 is provided between two layers 8, 9 of the main body 7, and a handle 10 is laterally protruded from the main body 7. The gate slide 6 is movable from a position where the aperture part 5 is opened to a closure position where the aperture part 5 is closed. The main body 7 is formed by folding a single moulded member along preset folding lines. A layer of the main body 7 formed by folding is then jointed. The gate slide 6 is part of the moulded member, and it is connected to the moulded member by a preset cutting line, thereby it can be cut from the main body 7 after folding and jointing of the moulded member. |
