Pneumatic coupling of two yarn ends designed of this type Yarn splicing devices for textiles producing packages with the working locations of the winding machines, for example, the coil autoinjectors. they have been known for a long time in connection with and numerous patents are described in detail in the specification.

With such yarn splicers, for example, a yarn breakage or two yarn ends formed by a controlled cleaning cut pneumatically, an almost twisted thread-like joint they can be connected in a way that will occur.

The surface of, for example, a package after a yarn break The upper thread collected on it is removed with the help of a suction jet and the thread is into the joining channel of the coupling prism of the coupling device. is placed.

Almost simultaneously, the lower thread, via a coupling tube, from a processing coil deployed in an unwinding position taken and likewise, the upper thread and the lower thread are then pneumatically merging channel in which they are mixed with each other in a swirling manner is placed inside.

However, such yarn connections have an almost twisted yarn-like they have an appearance and are approximately twisted yarn. different 'prerequisites' have been fulfilled for them to be in good health it has to be.

Both thread ends to be connected eg `First fully must be cut to length and carefully joined together It must be prepared and then fully assembled to measure the prism of the they must be positioned within the joining channel.

Known yarn splicing devices are referred to different devices for this purpose, small holding pipes and small unwind pipes as well as a thread As noted above, in practice both yarn ends are combined with a suction jet or area of the yarn splicer via the coupling tube they are moved into and here specifically, the merge each time to the yarn message allocated to the end side of the splicing channel of the cap They are wrapped in the joining channel by being shipped by means of their sheets. into the joining channel of the coupling prism of the coupling device. is placed.

The described method as well as the associated devices themselves in practice, Combining blends of fibers and synthetic fibers is also quite they have proven.

However, the situation is just right when the problem convict threads are to be combined. on the contrary, it is difficult to shape.

For example, compact conjugated yarns have high circuit including convict yarns or elastic synthetic fiber convict yarns The problem is in convicted yarns, known yarn splicing thread connections that can be manufactured with they require improvement.

Thus, in principle, by, for example, cotton fibers elastic having a high elastic '62 thread surrounded synthetic fiber twisted yarns, due to the highly elastic `Core yarn, a intense shrinkage during thread cutting, ie intense they tend to curl up sadly.

This means that such elastic synthetic fiber spun yarns, above when connected to one of the yarn splicers described, often on the one hand, small holding pipes of the thread ends and small twisting and preparation of unwind pipes and/or thread ends of the splicing prism of the yarn splicer overlapping in the joining channel, relatively strong shrinkage is the emergence of the problem of insufficient oliria due to curling, 'It is wherein the minimum part of the yarn ends after splicing outward from the merging channel of the merging prism.

Both events are, in principle, either failure to create or the splice connection causes it not to comply with the quality requirements.

Another problem is yarn splicing, which is also known in twisted yarns. in the application of the assemblies, during the joining process of the yarn ends through the merging channel of the merging prism as a minimum blowing out and forming yarn splicing The danger of low-value connections cannot be excluded.

The problem of this kind is to reliably split twisted yarns. therefore, different suggestions have already been made in the past.

Especially in conjunction with elastic synthetic fiber convicted yarns For example, in different shapes, into the joint canal region or in small In addition to the area of tether tubes and small unwinding tubes, yarn longitudinally cut ends by means of thread trimmers It is proposed to allocate locking means that fix it afterwards.

These locking tools ensure that the longitudinally cut thread ends are too shriveled and improperly prepared or during the joining process, the merging prism blowing completely or partially out of the duct they should prevent it.
