Abstract
Method of measuring a distortion angle between the longitudinal extent of the weft threads or rows of stitches in a textile strip (T) that is being continuously transported in a transporting apparatus (M) and the perpendicular to the transport direction, by means of a lighting arrangement (100A), a photoelectric sensor arrangement (107) with a plurality of sensor elements and an evaluation device (115) connected to the sensor arrangement for processing the values sampled from the sensor fields in order to obtain the distortion angle, wherein an arrangement of sensor elements with a plurality of rows and columns is used in which individual elements can be accessed as desired, and in a sequence of scanning steps different predetermined groups of sensor elements are interrogated, each of which is situated substantially on a sensor-field line, the groups involved in each scanning step being determined such that the scanned sensor-field lines are positioned at progressively altered angles with respect to the transport direction.
