摘要： A main drive shaft of a power loom reaches the rated operating rpm of the loom by the time of the first beat-up of the reed, thus avoiding start-up faults in the fabric. A flywheel mass is accelerated to a start-up rpm that is higher than the rated operating rpm before it is coupled with the main drive shaft. The start-up rpm is determined automatically and iteratively, with ever-increasing accuracy in successive starts of the loom. When the main drive shaft is coupled to the flywheel mass, the flywheel mass rpm decreases simultaneously as the main drive shaft rpm increases from standstill to the operating rpm. The actual main drive shaft rpm is measured at least at the time of the first beat-up and any deviation from the rated operating rpm is evaluated by the loom control. After each start-up, a new data set is generated based on the measured values and is used to calculate an updated or modified flywheel start-up rpm in the next start-up operation so that the main drive shaft more accurately reaches at least the rated operating rpm by the time of the first beat-up of the reed.

摘要： A picking method and apparatus for a multicolor picking loom to provide changes in the number of rotations of the loom in order to pick a desired weft. In particular, a signal generation unit outputs a weft selection signal for each weft corresponding to a picking number, and a number-of-rotations selection signal also corresponding to a picking number. A plurality of number-of-rotations patterns are preset and each pattern corresponds to one of the number-of-rotations selection signals. In addition, a plurality of picking conditions are preset which correspond to the particular weft selection signal for the selected weft and to one of the number-of-rotations patterns. Of the plurality of picking conditions, the picking condition is selected which corresponds to the weft selection signal and the number-of-rotations selection signal, which allows the desired and selected weft to be picked.

摘要： The picking mechanism has a torsion rod whose zero position is adjustable by an adjusting lever and an adjusting drive. A rigid wedge-shaped intermediate member movable by the adjusting drive is disposed between a sliding surface of the adjusting lever and a stationary sliding surface. Movement of the intermediate member produces a pivoting movement of the adjusting lever to alter the zero position. The intermediate member transfers a force exerted by the adjusting lever on to the stationary sliding surface.

摘要： A control method for a weaving machine comprises the steps of obtaining the rotational frequency to be varied by the use of the fuzzy interference on the basis of the evaluation index representing the running condition level of the weaving machine, and then varying the actual rotational frequency of the weaving machine on the basis of the obtained rotational frequency. As the evaluation index, use is made of the control allowance level of the weaving machine, the quality allowance level of woven fabric, the working allowance level of the operator, the stop level of the weaving machine, the rate of a change value of the stop level to a variation value of the rotational frequency or the operating rate of the weaving machine.

摘要： A method of controlling an operating speed of the loom for increasing the production rate by varying the present operating speed so as to be increased includes a step of estimating a stop rate at the final point of time during a predetermined period at a certain time during the predetermined period, and comparing the estimated stop rate with a predetermined limit stop rate, and setting the present operating speed to increase it when the estimated stop rate is less than the limit stop rate and to decrease it when the estimated stop rate exceeds the limit stop rate.
