The invention relates to a sieve frame for plan sifters and also to a method of producing it. It is used mainly in plan sifters for milling. The object is to improve the functionality of an insertable sieve frame and to simplify production. This object is achieved in that the sieve frame (1) including battens (2) is foamed from polyurethane in one part (and one operation), the sieve cloth (4) also being surrounded by foaming and the sieve frame (1) preferably containing a metal core (3)
