Abstract
A weft yarn presentation apparatus has a weft sequence control having weft thread presenting devices (1), a controlled thread clamping device (2) with several clamps (3a-3f) and a guide member (4) with a slit (5). The association of the weft thread presenting devices (1) with the clamps (3a-3f) guarantees that there is no cross-over of the tracks of the weft threads, and the displacement of the clamps in the reference plane (6) does not influence these tracks. The weft thread is presented to the gripper in the reference plane (6), through matching of the movements of the clamp and of the associated weft thread presenting device (1) so that contact between the weft threads is prevented.
