Abstract

In a particle filter for exhaust gases of internal combustion engines, particularly Diesel engines, including a filter body with filter pockets which are formed from sinter metal sheets and are wedge-shaped with an opening at the blunt end and edges formed by converging pocket side walls and arranged adjacent one another such that, between adjacent filter pockets, corresponding opposite spaces are formed with openings facing in a direction opposite to the openings at the blunt end, the filter pockets side walls are spaced from one another by widening means extending along at least an edge of the filter pockets so as to increase the width of the space between the side walls of the filter pockets.
