摘要

A filter element comprises a filter band having a spiral surface running parallel to the cylinder surface of a wound core, wedge-shaped spacers (31, 32) lying on the neighboring partial part of the filter band, and folding surfaces (37, 38). An independent claim is also included for the production of a filter element.
