Method for producing filter paper

摘要

A method for producing filter paper, in particular filter paper for preparing brewed beverages such as coffee or tea employs the steps of producing initially a noncrimped paper of high strength and subsequently rendering this paper capable of filtering through perforation and/or stamping or stamped perforation. The above method is advantageous in that a high production speed of the paper-manufacturing machine results since a crimping device (crimping cylinder, crimping scraper) is no longer required. Accordingly, the bottleneck caused by the crimping device speed is eliminated.
