摘要

A pressure element (1) is rolled over the surface of the printed products covered with the test paper. The pressure element is connected axially on both sides with a movably mounted guide element (3,4). The component joined to the axle (2) and producing the pressure force consists of a system of springs with adjustable pressure force. The system of springs is encased in a shaft (5) for manual or mechanical operation.
