Abstract:
A filter is made by the folding of a filter media to pleats after the application of strings of glue thereon and the glue serves as distance elements and fixing for the filter media. The glue contains an expandable filler, that when heated expands to a larger size that is then permanent. When the glue has set the filter is heated and the filler expands and expands the filter pleats.
