Abstract
A device for measuring the mass of fiber slivers contains an entry part for the fiber sliver to be measured and a measuring part adjoining the entry part. Arranged on the measuring part are two measuring members working on different measurement principles, specifically a so-called fiber-sliver mechanically, and so-called active-pneumatic measuring member for measuring the pneumatic pressure generated by the fiber sliver at a contraction. In addition to measuring the mass of fiber slivers, the device can be used for obtaining a characteristic variable for their composition or for separate regulation and monitoring in a control stage.
