摘要： A spinning machine includes a drafting device (7), an air-jet spinning device (9), and a yarn pooling roller (41). The drafting device (7) includes plural draft rollers, including a front roller (20), and drafts a fiber bundle (8). The air-jet spinning device (9) performs spinning to form a yarn (10) by twisting the fiber bundle (8) drafted by the drafting device (7). The yarn pooling roller (41) pools the yarn (10) formed by the air-jet spinning device (9) by winding the yarn (10) around a surface thereof. A peripheral speed of the front roller (20) during yarn discharge spinning and during regular spinning performed after yarn discharge spinning is different. A peripheral speed of the yarn pooling roller (41) during the yarn discharge spinning and during the regular spinning is different.

摘要： A flyer frame having a device for detecting a tension and constructed by photoelectric transducer units 26 arranged between a front roller 3 and a flyer top 4a for detecting a tension of a roving running to a bobbin during a data entry winding period from an empty state to a full bobbin state. A unit is provided for obtaining data for a correction of the bobbin speed, to thus obtain a desired tension. The corrected data at each corrected timing, such as a point of a change of the movement of a bobbin rail, is stored in a memory. The stored data is used instead of the tension detection for correcting the bobbin rotational speed during a usual winding period after the data entry period.

摘要： The invention concerns a method wherein at least one yarn is unwound from at least one bobbin (2) by means of a baulk (10). The unwinding speed is developed and, in co-ordination, the other related parameters of the transformation process, based on a quantity representing the amount of yarn still wound on at least one of the bobbins (2), so that said unwinding speed remains within the limits imposed by the unwinding conditions.
