Abstract
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 material from a measuring zone between the pairs of rolls. There are provided two weighing plates, each of which is pivotable about an axle and connected with a measuring signal transmitter, the signal of which depends on the pivoting angle of the plate. An endless belt which contactingly glides across the weighing plates and which is driven at the speed of movement of the layer of fiber material is provided for transporting the layer of fiber material.
