Abstract

Headbox turbulator for a machine for making a fibrous web from a fiber suspension comprises a set of tubes, at least one of which has an insert providing at least one stepwise change in diameter. The insert has a ratio of outside diameter to length of 1:8-50 : An independent claim is also included for a process for producing an insert as above, in which functional contours of the insert are produced by machining.
