Abstract
A loom is provided with a closed path for the weft yarn from a yarn package to a picking nozzle. A first yarn guiding passage extends from a yarn clamp to a weft yarn storage device while a second yarn guiding passage extends from the storage device to the picking nozzle. Sensors are disposed along the path of the yarn in order to sense the presence or absence of a thread for searching/rethreading purposes. The second yarn guiding passage is articulated to the storage device and the picking nozzle in order to follow movements of the picking nozzles relative to a reed.
