Abstract: An edge closure system is presented herein wherein a portion of the closure edge of the filter bags leading to the outlet pipe aperture are provided with mating snapping closures, allowing to sealingly close the length of the edge of the fabric leading to the outlet pipe aperture simply by engaging the male and female components of the snapping closures. Moreover, an outlet pipe closure system is also presented herein using a combination of a tongue mounted internally to one of the sides of the fabric forming the bag in a manner to be wrappable around at least a corresponding portion of the outlet pipe, and a fabric hood mounted externally and overlapping both sides of the bag at the outlet pipe aperture, which cooperates with the tongue to seal the interface between the outlet pipe and the bag when held in position.
