Abstract (en)
[origin: US5158635A] A connecting member for filter bags or the like used for collecting dust has a main body secured to the filter bag, which main body has a multi-ply structure of board or cardboard. The main body has a passageway therethrough for facilitating the passage of dust into the filter bag. A slide gate is arranged on the main body between two plies of the main body and a handle thereon projects laterally beyond the main body and is movable between a moved in position leaving the passage opening uncovered and a moved out position shutting it. The main body is folded from a single piece of material cutout along preset fold lines. The plies of the main body placed on top of each other after folding are bonded together. The slide gate is at least partly a component of the cutout and is connected with the rest of the cutout via preset tear lines so that the slide gate may be torn off to the side after folding and bonding.
