Abstract
Disclosed is a weaving method with which the yarn tension of several part groups with at least one warp thread per part group is controlled or adjusted separately, in order to follow a respective reference yarn tension profile during weaving, where, for at least one part group, the reference yarn tension profile is changed during weaving, where the reference yarn tension profile is determined and changed separately for at least two part groups, and where each reference yarn tension profile is selected from a collection of different reference yarn tension profiles. Also disclosed is a weaving machine provided with yarn tensioning elements, a storage unit in which said collection is provided, and a control or steering unit in order, in cooperation with the yarn tensioning elements, to adjust or control the yarn tension in separate warp threads using the indicated weaving method.
