The invention relates to a mounting arrangement for a working tool in a production machine for a product with a risk of contamination, especially in a roller press, for material in powder form. The arrangement comprises a seal (12, 13) which seals off the mounting area (11) from the working tool (2). According to the invention, the mounting area (11) is closed off from the environment and is connected to a vacuum source in order to prevent foreign substances from the mounting arrangement (9) from entering the area of the working tool (2). Even if the seal (12, 13) should become defective, foreign substances are prevented from leaving the mounting area (11). |
