Abstract
The invention relates to a method and apparatus in which an elongated body (1) such as a yarn, a roving or a band, is measured continuously by means of a simple cost-effective sensor (5). A further, more complicated sensor (8) which works more accurately but more slowly is triggered by the simpler sensor if the latter indicates special events. These events are then stored by the complicated sensor and are subsequently analyzed accurately in a greater amount of time. The entire time span occurring between two special events can be utilized for this analysis.
