A bag filter assembly incorporates a front frame (1) which encloses two or more filter bags (2) the mouths of which respectively have stiffening frames (3). The individual filter bags (2) are joined to each other, the stiffening frame (3) and the front frame (1). The novelty is that the front frame (1) has a gap (4) over which is fitted a U-shaped outer frame with locking rims (1.1) forming a surrounding inward-facing space (5). The distance between the closed rims (1.1) is less than the width (B) of the stiffening frame (3) after insertion and provides a dust-tight seal between adjacent stiffening frames (3) and the surfaces of the inward facing spaces (5). The stiffening frames (3) are inserted in the open gap (4) and are subsequently held by the U-shaped locking rims (1.1). |
