摘要

The sieving device has a laminar functional layer (3), particularly provided for use in a transmission guide plate. The functional layer is provided with sieve portions with pre-selected sieve openings (19). The sieve portions cover a medium flow for separating particle impurities. The medium flow crosses the functional layer. The sieve part is an integral part of the functional layer.
