Characterizing an elongate textile product

摘要

Readings of a characteristic of the yarn along the longitudinal direction of the yarn are detected. Values of a yarn parameter are determined from the readings. An event field contains a quadrant of a two-dimensional Cartesian coordinate system, whose abscissa defines an extension of yarn parameter values in the longitudinal direction and whose ordinate defines a deviation of the yarn parameter from a desired value. Densities of events in the event field are determined from the values of the yarn parameter and their extensions in the longitudinal direction. A yarn body is represented as an area in the event field. The area on the one hand is delimited by the abscissa, on the other hand by the ordinate and further by a line in the event field that substantially follows a constant event density. The representation of the yarn body permits a clearing limit to be defined in a rapid and rational manner.

1. A processor-based method for characterizing an elongate textile product to be tested that is moved along its longitudinal direction, the method comprising the steps of:
detecting readings of a characteristic of the elongate textile product to be tested along the longitudinal direction of the elongate textile product to be tested with a sensor, determining, with a processor, values of a parameter of the elongate textile product to be tested from the readings, providing an event field that contains at least a part of a quadrant of a two-dimensional Cartesian coordinate system, having an abscissa that defines an extension of parameter values in the longitudinal direction and an ordinate that defines a deviation of the parameter from a desired value, and determining densities of events in the event field from the values of the parameter and their extensions in the longitudinal direction, wherein a body of the elongate textile product to be tested is represented in the event field as an area that is delimited by one of the abscissa and a first straight line running parallel thereto, by one of the ordinate and a second straight line running parallel thereto, and by a third line in the event field that follows a constant event density.
