Method and apparatus for continuously determining the fineness of fibers in slivers

An apparatus for continuously measuring a fiber fineness in a sliver, comprising:

• at least two sensors that produce various type data signals;
• a calibrating unit for calibrating said various type data signals relative to a constant sliver length;
• and
• a processing unit that forms fiber property parameters from said various type data signals produced by said at least two sensors, at least one sensor being designed to produce a signal that is proportional to a sliver property which is measured in combination with other sliver properties by another sensor, such that a non-directly measurable sliver property can be determined.

An apparatus for continuously measuring a fiber fineness in a sliver, comprising:

• a plurality of sensors;
• a processing unit for forming fiber property parameters based upon signals from said sensors;
• and
• a calibrating unit that calibrates said signals relative to a constant sliver length.
