Abstract (en)
A weft thread tensioning device, comprising a weft thread path defining arrangement having two weft thread passage elements (24, 26) positioned at a distance with respect to each other for receiving a weft thread such as to extend along a straight weft thread path (P) extending between the weft thread passage elements (24, 26), a weft thread deflection element (28) positioned between the weft thread passage elements (24, 26) in the direction of the weft thread path (P), the weft thread deflection element (28) being movable such as to act on a weft thread extending across the weft thread passage elements (24, 26) for deflecting the weft thread between the weft thread passage elements (24, 26) out of the straight weft thread path (P), and a deflection element drive (34) operable for moving the weft thread deflection element (28), the deflection element drive (34) having a controller (38) associated therewith for controlling the movement of the weft thread deflection element (28) for deflecting a weft thread extending across the weft thread passage elements (24, 26), is characterized in that the deflection element drive (34) comprises a rotary electric motor (36), and that the weft thread deflection element (28) is coupled to a rotor shaft of the rotary electric motor (36) and is arranged for carrying out a swiveling movement about a swivel axis (A) that is substantially parallel to the straight weft thread path (P).
