ABSTRACT:
A method for manufacturing a filter insert, and the filter insert so manufactured. The filter insert includes an accordion fold pack that is made of a filter material and is joined to a filter frame. The material of the filter frame is injected in a flowable state into the folds of the accordion fold pack which are open in the on-coming flow direction of the medium to be filtered. The material is subsequently hardened during automatic claw fixation with the fold walls. The entire peripheral edge of the accordion fold pack sealingly overlaps the outer boundary surfaces of the filter frame, and is designed as a sealing device.
