摘要： A yarn feeder is provided with a drum which is driven to rotate by a motor controlled by a control unit for drawing yarn from a reel and winding it upon itself in the shape of loops forming a stock. The control unit estimates the stock on the drum on the basis of an information indicative of the amount of yarn which is unwound from the drum upon request from a downstream machine, and of an information indicative of the amount of yarn which is wound on the drum, and retroactively controls the motor to substantially stabilize the stock on a reference value. The control unit also performs a parallel correction routine in which compares the stock with the reference value to estimate a stock status RES

摘要： The tension is modulated by a weft-braking device controlled by a tension control block programmed for comparing the measured tension with a reference tension, and for transmitting a braking level signal to the weft-braking device, which braking level signal is adapted to minimize the difference between the measured tension and the reference tension. The yarn consumption speed is calculated, then the yarn consumption speed is compared with a predetermined threshold speed, and if the calculated consumption speed overcomes the predetermined threshold value, the tension control block is enabled, while, if the calculated consumption speed is lower than the threshold value, the tension control block is disabled and the last signal generated by the latter is maintained as braking signal, until the yarn consumption speed overcomes again the threshold value.

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 method and apparatus for monitoring the scanning conditions when controlling a yarn feeding device including a storing surface for the yarn, a drive motor, a sensor device having at least one sensor oriented towards a scanning zone defined in the yarn feeding device, and a control circuit connected to the sensor device. The sensor generates an object-output signal for control purposes in response to the movement, absence or presence of an object in the scanning zone. A test signal is formed from and substantially synchronously with the object-output signal, and the signal level of the test signal is compared with an alarm threshold value representing a just barely acceptable deterioration level of the scanning conditions. An alarm signal is generated when the signal level of the test signal falls below a predetermined threshold value.

摘要： In a yarn feeder (2), the yarn feed may be effected by a yarn reserve (11) support spool (2), which is arranged to rotate by means of a motor (60). The yarn is taken up by and unwound from the spool as the latter rotates. Unwinding of the yarn reserve on the spool is not controlled. The size of the yarn reserve is monitored and yarn take-up is controlled accordingly. The unit also includes electrically contactless sensing and control devices (3), which are preferably located immediately adjacent to the rotary spool. The unit (3) is designed to sense the presence and quantity of yarn on the yarn reserve support surface (10) of the spool. The unit also controls the said motor.

摘要： A thread-delivery device is disclosed including a storge body formed by bars disposed in the shape of a polygon. The bars form two axially-spaced sections of approximately equal circumferential length. A cylindrical member having sawtooth-shaped threading grooves is rotated between the bars of the first section. The bottom of the threading grooves is located radially inwardly of lines interconnecting the bars. A ring having a conical face is disposed at the thread entrance opening adjacent to one end of the first section and a sensing device is provided to sense the endmost thread wound on the second section.

摘要： The thread storage and supply arrangement comprises a storage drum having a peripheral thread storage surface onto which is to be wound a succession of adjoining turns of thread, the thread storage surface comprising a thread infeed region at one axial end of the storage surface and a thread outfeed region at the other axial end. A thread infeed structure located at the thread infeed region guides thread onto the peripheral storage surface to form a succession of adjoining turns of thread. A thread outfeed structure located at the thread outfeed region feeds off the storage drum thread which is to be pulled off. The peripheral storage surface, at the thread infeed region thereof, curves radially inward in the direction from the infeed to the outfeed region and, at the thread outfeed region thereof, curves radially outward in the direction from the infeed to the outfeed region. Relative rotation between the storage drum, on the one hand, and the infeed and outfeed structures, on the other hand, is effected by a controllable drive motor or by a controllable coupling which can be coupled to a continuously operated drive motor. An electrooptical control device activates and deactivates the motor or coupling in dependence upon the extent to which thread is wound about the peripheral storage surface of the storage drum.
