Abstract
The deviations in measuring the density of the fiber strand caused by manufacturing tolerances in the take-off rolls are monitored by integrating the deviations in densities from a preset value over periodic intervals in a control device. The integrator is controlled by periodic impulse signals and is used to adjust the transporting air stream so as to regulate the pressure drop to achieve an even strand.
