Abstract
Disclosed is an improved basket filter which minimizes raw material waste and is formed of at least one rectangular perforated metal foil part folded along a bending line at its middle, transversely to its longitudinal edge, and at least two perforated metal foil elements in the form of sectors of a circle. The longitudinal edges of the rectangular metal foil part are connected to the straight line edges of the metal foil elements in the form of sectors of a circle so that, after assembly, the filter defines a round opening which merges into a straight line bottom edge. Adjoining edges between the rectangular metal foil part and the straight line edges of the metal foil elements are embedded in a plastic.
