DETECTION METHOD OF YARN SUPPLY ON SURFACE OF YARN STORAGE AND SUPPLY FACILITY AND THE YARN STORAGE AND SUPPLY FACILITY PER SE

摘要

To determine the movement of the yarn stock limit on the storage container surface of the yarn storage device and the yarn supply, different sensed properties of at least two circumferentially spaced peripheral sections of the storage container surface are sensed simultaneously by sensors and these sensed properties are converted to storage tank surface signals that are non-identical to each other and which are distinguished from yarn signals that are identical to each other. The yarn signals are generated in said sensors and are produced based on the sensed property of the fiber winding when the yarn supply reaches the sensing zone. The yarn storage device (F) and yarn supply device (F) has a first and a second storage surface peripheral section (8, 9) that are mutually different in terms of their sensed properties (A, B), and a plurality of sensors (S.sub.An). , S.sub.Bn, S) which are spaced apart from the periphery of the storage container (1) such that at least a first peripheral portion (8) of the storage container surface
