Abstract
A weft thread tensioning device includes a weft thread path defining arrangement having two weft thread passage elements positioned at a distance with respect to each other for receiving a weft thread such as to extend along a straight weft thread path extending between the weft thread passage elements. A weft thread deflection element is positioned between the weft thread passage elements in the direction of the weft thread path. The weft thread deflection element is movable to act on a weft thread extending across the weft thread passage elements deflecting the weft thread between the weft thread passage elements out of the straight weft thread path. A deflection element drive moves the weft thread deflection element and includes a controller associated therewith for controlling the movement of the weft thread deflection element for deflecting a weft thread extending across the weft thread passage elements.
