Abstract
A process is disclosed for sampling textile fiber skeins. A fiber skein (2) continuously moved in the longitudinal direction (23) is intermittently brought to a stop within a defined section (4, 28). The profile of the immobilized section (4, 28) of the fiber skein (2) is flattened at least in partial region (24) and the textile analysis is carried out on this temporarily immobilized, flattened partial region (24) of the fiber skein.
Claims16
A method for non-destructively analyzing samples of a textile fiber strand comprising the steps of
- continuously moving an elongated fiber strand longitudinally to a testing location;
- temporarily stopping a selected segment of the strand at the testing location;
- flattening the selected segment while it is stopped;
- analyzing the flattened segment while it is stopped;
- and
- resuming the longitudinal motion of the selected segment.
An apparatus for non-destructively analyzing samples of a textile fiber strand without removing the samples from the strand comprising the combination of
- means for longitudinally delivering a continuously moving textile fiber strand to a testing location, for longitudinally removing tested strand from the testing location, and for temporarily stopping a segment of said strand at the testing location while accumulating slack in said strand at a delivery side of said testing location;
- means at said testing location for flattening said segment of said strand;
- and
- means at said testing location for analyzing said segment while said segment is stopped and flattened.
An apparatus for non-destructively analyzing samples of a plurality of textile fiber strands from a plurality of sources of strands without removing the samples from the strands comprising the combination of
- a plurality of means for longitudinally delivering a plurality of continuously moving textile fiber strands to individually testing locations, for longitudinally removing tested strands from the testing location, and for temporarily stopping segments of said strands at the testing locations while accumulating slack in said strands at a delivery side of said testing locations;
- means at each said testing location for flattening said segment of a strand delivered thereto;
- means at each said testing location for analyzing said segment while said segment is stopped and flattened;
- and
- a central computer connected to control each said means for delivering, removing and stopping and for controlling each said means for analyzing.
