ABSTRACT:
A pocket filter includes a front frame which accommodates at least two filter bags. The top of each bag accommodates a reinforcing frame. The bags are secured dust-tight to one another, to the reinforcing frames, and to the front frame. The front frame is a severed at at least one point along its perimeter. The front frame has a U-shaped channel around it that opens inward, and the reinforcing frames can be inserted into the channel when the front frame is open at the severed point. The reinforcing frames match each other and match the size of the front frame, creating a dust-tight contact between all the adjacent reinforcing frames and the inner surface of the channel when the front frame is closed at the severed point. Facing webs, disposed in the channel opening on each side of the "U", create a dust-tight contact with the reinforcing frame.
