P9 5S02 ABSTRACT OF THE DISCLOSURE A process and apparatus for the manufacture of a pleated filter insert made of a thermoplastic material. The pleat walls are maintained at a distance with the filter pleats open in the direction of outflow of the filter insert by elongated ribs made of the filter material itself. The tape-like filter material is gathered in a first process step. The elongated ribs are produced by means of tension-free, permanent shaping of the gathered filter material, heated to a temperature which is below the shrinking temperature and above the deformation temperature of the filter material, between the jaws of a shaping device. The intermediate areas of the filter material intended for the forming of pleat wall edges are heated by at least one heater jaw to a temperature which is between the deformation temperature and the melting temperature until the irregularities of the filter material in the intermediate area have been smoothed out. The filter insert, provided with elongated ribs in the filter pleat wall for maintaining a distance also maintains the original filtering properties in the pleat walls, has a smooth surface at the pleat wall edges, and has sufficient stability.
