摘要： The present invention provides a method and apparatus which enables thread to be wound onto the motor driven storage drum of a thread storage and feeding device for a thread processing machine strictly continuously and uniformly with the aim of ensuring that the thread as wound off the thread supply bobbin is wound onto the storage drum in such a way that variations in the tension of the thread as pulled off the storage drum are eliminated. This is achieved by controlling the number of revolutions of the motor in response to a control signal which is derived from the thread intermediate supply on the drum and the actual thread consumption, i.e., the average speed of the thread leaving the drum.

摘要： A motorized rotary drum supported on a motor housing bears a plurality of yarn loops wound thereon, such loops being adapted to be unwound upon request from a downstream machine. A yarn-unwinding sensor comprises light-emitting elements and light-receiving elements both of which are integral with the motor housing. Light-guiding elements which are integral with the drum guide the light from the light-emitting elements to a window which is defined on the rotary drum in a position such that it is repeatedly engaged by the yarn during its rotary unwinding motion, and vice versa. A reflecting surface reflects the light coming out of the window back towards the window. Light-deviating elements which are integral with the motor housing deviate the light coming back from the window towards the light-receiving elements. The unwinding of a yarn loop from the drum is determined on the basis of the variation of light resulting from the yarn transiting on the window.

摘要： A feeler for monitoring a thread reserve in weft feeders, comprising a light-emitting device constituted by a light source which directs light rays onto a thread wound in spaced turns on the drum of the feeder, and a receiver which collects the light rays and converts them into electrical signals that indicate the presence or absence of turns of thread. A first focused optical transmission system forms a first pointlike luminous image of the light source on the turn being monitored and, in the absence of the turn, a second pointlike luminous image of the light source located on a screen surface which is arranged below the turns. A second focused optical projection system selectively projects the first or second luminous image, along respective differentiated optical paths, onto at least one optical sensor which emits discriminated signals that correspond to the length of the corresponding optical paths.

摘要： For determining the movement of a thread supply boundary on the storage surface of a thread storage and feed device, different scanning properties of at least two circumferentially offset circumferential sections of the storage surface are scanned simultaneously and converted into storage surface signals which are nonidentical among themselves and which are discriminated from thread signals which are identical among themselves. The thread signals are generated by sensors which scan a scanning zone on the storage surface and formed on the basis of a scanning property of the thread windings when the thread supply is present in the scanning zone. The thread storage and feed device is provided with first and second circumferential sections on the storage surface differing from one another with respect to their scanning properties, and a plurality of sensors. The sensors are spaced approximately in the circumferential direction of the storage body in such a way that at least a first circumferential section of the storage surface can be scanned by one sensor and, simultaneously, a second circumferential section of the storage surface can be scanned by at least one additional sensor.

摘要： A weft feeder comprising weft sensors with movable magnetic elements that cooperate with respective detectors located outside the feeder drum; the detectors react with a signal, without contact, when the position of the corresponding weft sensor changes. Each detector in turn comprises an acquisition sensor capable of providing an analog signal, in terms of voltage, that can vary in a linear manner as the angular positions of the movable magnetic elements of the weft sensors vary. The acquisition sensors are operatively connected to a microprocessor for controlling the motor of the feeder, which is programmed to automatically set the values of the weft presence threshold and of the weft absence threshold and to filter the values of said signals.

摘要： In a sensing and analyzing system for a yarn feeder with yarn storing unit, one or more sensor elements which may be coupled to one or more circuits are used for evaluating or sensing sensor information. At least one sensor element is placed in the unit, from a yarn detection standpoint, in an uncritical relationship to the unit's yarn transporting surface and a yarn turn travelling forward on this. The transmitting members are designed to relay information from each sensor element in the unit in unprocessed or processed form to receiving members located outside the unit. Energy emitting members within the unit ensure energy supply to the sensor elements and the circuits belong thereto. When using optical emitting elements, these are included in an arrangement which supplements or alternatively substantially reduces the influence of vibrations in the unit on the sensing or analyzing result.
