Weighing apparatus for continuously weighing a passing layer of fiber material in a metering dev |
January 9, 1979 |
| Weighing apparatus for continuously weighing a throughpassing layer of fiber material in a metering device of a spinning preparatory machine with two pairs of rolls arranged at a distance from one another for supplying the layer of fiber material to and for taking-off the layer of fiber |
| 4041770 |
Method and apparatus for sensing the thickness of a fiber layer on a moving surface |
August 16, 1977 |
| A pneumatic measuring means is placed over the main cylinder to measure pressure variations due to changes in fiber layer thickness. The measured pressures are transmitted to a measuring and control means which compares the measured pressures to a pre-set value and produces a difference |
