    摘要: The wall of the friction spinning element has bores or holes with a predeterminate bore diameter and a coating on their side facing a fiber feed duct, the coating extending over the bore edges into the bores. Each bore or hole thus formed has a diameter at the bore or hole entrance or inlet which is smaller than the bore diameter of the related bore or hole. Each bore or hole has a cross-sectional area of less than 0.283 mm.sup.2, but amounting to at least 0.07 mm.sup.2. In this way, the undesirable penetration of fibers or fiber parts into the bores or holes is prevented as far as possible when air flows through the bores or holes at the side of the coating, while retaining a hole form or configuration which is favorable from the standpoint of airflow and blockage of the bores or holes.

    摘要: In the manufacture of friction spinning drums, in order to be able to select the size of the holes or perforations, on the one hand, to oppose technological fiber loss and jamming of sucked in foreign particles and, on the other hand, to provide airflow advantages, it is proposed to manufacture the friction spinning drum from a thick-walled support and a thin-walled perforated body. As a result, holes or perforations having a sufficiently small cross-section to counteract the above-mentioned fiber loss can be formed in the thin-walled perforated body. On the other hand, holes or perforations having a large enough cross-section to prevent jamming of sucked in foreign particles or other contaminants can be provided in the thick-walled support.

    摘要: The method of, and apparatus for, producing a yarn uses a friction spinning device comprising a perforated first friction spinning drum and a second friction spinning drum which can also be perforated. Two fiber feed passages project to the first friction spinning drum and are each supplied by opening assemblies which individualize or individually separate the fibers. The fibers are transported toward the first friction spinning drum using a feed air stream in the fiber feed passages. This feed air stream is produced by the first friction spinning drum which is maintained under sub-pressure. Advantageously, the fiber double-feed to the friction spinning drum permits supplying two different fiber types to the same yarn end. Also, different inclinations of the fibers at the friction spinning drum can be obtained by different inclinations of the fiber feed passages in order to produce yarns of different character. The first and second friction spinning drums can be each divided into cooperating drum sections to define a first pair of coacting drum sections and spaced therefrom a second pair of coacting drum sections. The respective pairs of drum sections can be operated at different rotational speeds and can be subjected to different vacuum conditions.

    摘要: In a false twist spinning unit a fiber sliver is removed from a fiber sliver can and fed into a drafting mechanism. The fiber aggregation delivered by the drafting mechanism is received by a suction portion of a spinning unit and is passed to a twist-imparting element which produces a spun yarn. The spun yarn is withdrawn by a roller pair and passes via a yarn monitoring device to a winding unit. The suction pressure required for the suction portion is produced by a suction device. In the event of blockage of the suction portion, a cleaning element or device is activated. After cleaning of the suction portion is completed, spinning is restarted.

    摘要: To piece up a yarn in a friction spinning device, fibers supplied to a yarn formation position of a friction spinning drum are twisted to form a twisted fiber structure until the latter has sufficient strength for grasping by a suction device moved towards the twisted fiber structure end opposite to yarn withdrawal. The suction device grasps this end and stops such twisted fiber structure. Further fibers wound about the now substantially stationary twisted fiber structure strengthen the so it can be withdrawn by the suction device. Due to such withdrawal and constant further supply of fibers, a yarn-like structure is formed adjoining the twisted fiber structure and such yarn-like structure is also withdrawn. To subsequently again form the actual yarn, withdrawal rollers are engaged so the yarn produced at the yarn formation position is withdrawn at production speed or with a reduced speed still sufficient for forming a yarn. Then the twisted fiber structure and the adjoining yarn-like structure are taken-up by the suction device. Thereafter, taken-up yarn can be transferred to a wind-up device. In the event of a yarn break, the newly-produced yarn is supplied at its yarn end to a yarn-connecting or piecing device which also simultaneously receives a yarn end from the unfinished package. The two yarn ends are interconnected and during such time, the continuously delivered, newly-produced yarn is taken-up by an intermediate storage device, the stored yarn being taken-up again by the package after connection of the two yarn ends.
