Abstract

A filter element 1 such as for a motor vehicle air filter and in the form of an annular cylinder of pleated filter paper has a continuous line 2 of adhesive extending over the whole width of the strip of pleated paper, on the internal and/or external surface of the element, to form a support lattice which resists crushing stresses in normal use of the element. The adhesive is applied continuously from nozzles whilst the strip of pleated paper is flat prior to being cut and bent into the annular cylindrical configuration. <IMAGE>
