<p>The present invention relates to a yarn storing, feeding and measuring device (1), particularly for jet looms, having a stationary drum (2) onto which an intermediate yarn store is wound by a winding-on device (3) and from which the yarn (F) is withdrawn, yarn sensing means (6) detecting the withdrawal of the yarn from the drum generating pulse signals indicating that the yarn passes a detection area of the yarn sensing means (6), a plurality of yarn stopping devices (10) being arranged at angular intervals around the storage drum (2) and a control device (8) adjustable to desired yarn lengths to be withdrawn, said control device being responsive to said pulse signals such that an actuating signal is transmitted to a selected yarn stopping device (10) whose angular position corresponds to the position rendered by the yarn when said desired yarn length has been withdrawn. Prior art devices of the above mentioned type required a great number of yarn sensors, said great number resulting in high costs of said device. The present invention improves this state of art by a device in accordance with the above mentioned type, wherein the yarn sensing means consists of yarn sensors (6), the number thereof being lower than and independent from the number of yarn stopping devices (10), and wherein said</p> |
