Abstract

The folded thermoplastic filter element for mounting between inlet and outlet is mfd. such that the folds open to the outlet side are held apart by oblong, embossed portions (15) formed in the material. The material web forming the element is transported in its longitudinal direction is first pleated in the transverse direction for the amount necessary to form the embossed portions. The latter are produced by stress-free permanent shaping, with the material heated to above shaping and below shrinkage temp. between jaws. Then it is cooled below the shaping temp. The linear folds are formed by jaws heated to between shaping temp. and melting point until all unevenness is smoothed out and then cooled again.
