摘要： A technique for crimping multifilament threads involves a device having an injector installation and having a stuffing installation. The injector installation has a conveying duct having a thread inlet. The conveying duct of the injector installation opens into a stuffer chamber of the stuffing installation. The stuffer chamber in an upper chamber portion, between a plurality of wall portions of a chamber wall, has a plurality of slot-shaped air-exhaust openings. The wall portions of the chamber wall, in order to configure the air-exhaust openings, each have one flow edge which is aligned so as to be tangential to a chamber circle.

摘要： Techniques are directed to melt spinning, drawing, crimping and winding multiple threads. The threads are spun from a plurality of spinnerets of a spinning device and are drawn as a thread group by a drawing device and are subsequently fed for crimping next to one another to a plurality of texturing units. In order to obtain identical treatment of all threads within the thread group, the threads are guided individually with a plurality of wraps next to one another on a godet unit and, after running off from the godet unit, are guided in a straight thread run parallel next to one another into the texturing units. To this end, adjacent texturing units of the crimping device form a treatment spacing between themselves which is such that, in the case of being guided individually with a plurality of wraps on the godet unit, the threads can be guided in parallel in a straight thread run.
摘要翻译：技术涉及熔融纺丝，拉丝，卷曲和缠绕多根线。螺纹由多个纺丝装置的喷丝头纺出，并通过拉丝装置拉伸成螺纹组，并随后进给到多个纹理单元。为了对螺纹组内的所有螺纹进行相同的处理，螺纹在导丝单元上彼此相邻的多个卷绕单独引导，并且在从导丝组件移出之后，以直线平行的方式引导彼此相邻进入纹理单元。为此，压接装置的相邻的纹理单元在它们之间形成一个处理间隔，使得在单独引导导丝单元上的多个包装的情况下，可以将线形平行地引导成直线跑。

摘要： An apparatus feeds a plurality of threads to rotating godets of a melt spinning machine including a manual injector (e.g., a main manual injector) and a cutting device. In order to be able to selectively feed the threads individually or as a bunch, a transfer device and a second manual injector (e.g., an auxiliary manual injector) are associated with the manual injector.

摘要： Various techniques involve a device for entangling a plurality of individual threads of a composite thread in a melt-spinning process for the production of crimped yarns. The device to this end has a plurality of entanglement nozzles which are collectively held on a support. In order to enable a flexible utilization of the entanglement nozzles and of thread guiding, the entanglement nozzles on the support are assigned at least one thread guide in such a manner that the threads are guidable optionally in the entanglement nozzles and/or in the thread guide.

摘要： A device for pneumatically conveying and guiding a multifilament thread has a closed conveying channel which has a thread inlet opening at one end and a thread outlet opening at the opposite end. An injector zone having at least one compressed air channel which opens into the conveying channel is formed between the thread inlet opening and the thread outlet opening, wherein the compressed air channel can be connected to a compressed air source. In order to avoid blowing air from flowing back from the injector zone at the thread inlet opening, a return flow channel is formed in a channel section of the conveying channel between the thread inlet opening and the opening of the compressed air channel, which return flow channel connects the conveying channel to ambient atmosphere.
