Abstract

Abstract In GB2315704 Carl Freudenberg describes a method for producing a pleatable filter material from a thermally bound nonwoven material. A fibrous web is formed from drawn and non-drawn synthetic fibres. It is subsequently calendered, being consolidated between profiled calender rolls so as to be stress-free over its crosssection and without nonhomogeneities. Spacers are also included for spacing apart folds subsequently formed in the material.
