Abstract (en)
The dust filter bag has walls of weldable flexible filter material with front (2) and rear walls, folded side walls, an inlet opening in the front wall and an essentially rectangular shape closed by weld seams at the longitudinal ends. The bag walls are welded using weld seams (18-23) in such a way that the side folds (10,11) can be inverted out from their folded positions between the front and rear walls so as to form lateral extensions of the front and rear walls.
