Patent

CA 2369311

The object of the invention is a process for producing a filter paper, in particular a filter paper for the preparation of brewed beverages such as coffee or tea, The concept forming the basis of the invention consists of, first, producing an uncreped paper of high strength, and subsequently making this paper filtration-capable through perforation and/or impressing, or through impressed perforation. The advantage of the high rate of production of the paper machine results from the fact that a creping device (creping cylinder, creping blade) is no longer necessary, and thus the bottleneck of the machine speed is done away with.
