Method for making filter insert, involves utilizing zigzag shaped folded filtering agent, where bending edges are stamped in first step

摘要

The method involves utilizing a zigzag shaped folded filtering agent, where the bending edges are stamped in a first step, and subsequently a folding is carried out, where two glue beads are applied on the side edges of the filtering agent after the folding, which run along the folded filtering agent. The folded filter material is separated into individual filter elements by a cutting device and the individual filter elements are inserted into a frame, which has a contour, which enables coating of the filter element with a thermoplastic synthetic material for building a frame.
