Yarn-joining prism, method of manufacturing same, and insert for yarn-joining prism

Abstract

The present invention relates to yarn-joint prisms, methods of making the same, and inserts for yarn-joint prisms. Yarn splicing device for knot-free joining of two ends of yarn in a station (2) of a textile machine for the manufacture of cross-wound bobbins, in which the yarn splicing prism (23) has two splicing channel cavities capable of receiving the action of the airflow (17, 18) of the yarn-joining channel (41), the axes (26, 27) of the yarn-joining channel cavity are arranged at mutually staggered positions in the axial direction. The invention provides that the yarn joining prism (23) has a support slot (19) arranged between said yarn joining channel cavities (17, 18), in which support slot the insert (30) can be positioned or be positioned, The insert is provided with an inlay seam (34) with rounded edges forming the butt joint that occurs between the splicing channel cavities (17, 18) when the insert (30) is mounted edge.

Description

technical field [0001] The invention relates to a splicing prism for a splicing device for knot-free joining of two ends of yarn in a station of a textile machine for the manufacture of cross-wound bobbins, wherein the splicing prism comprises two In the yarn-joining channel of the yarn-joining channel cavity, the axes of the yarn-joining channel cavity are arranged at mutually staggered positions in the axial direction. Background technique [0002] In the textile industry, yarn splicing devices for knot-free joining of two yarn ends have long been known in various embodiments. [0003] Such a yarn joining device known especially in connection with the stations of automatic winding machines allows to produce almost yarn-like yarn splices by means of the airflow swirling of the two yarn ends, which not only have a similar strength to the yarn , also has a similar appearance to yarn. [0004] In connection with the stations of automatic winding machines it is known that whe...

AI Technical Summary

Problems solved by technology

[0020] This yarn splicing device comprising the yarn splicing prism of which the yarn splicing channel has two slightly staggered yarn splicing channel cavities ensures that the yarn end is relatively reliably positioned in the yarn splicing channel during the yarn splicing process, but has no The unnoticeable disadvantage is that the manufacture of such yarn-joint prisms is relatively complex and thus expensive

That is, the butt edges of the splicing tunnel cavities that occur between the splicing tunnel cavities have to be carefully machined, i.e. complicated and slowly smoothed, in order to avoid damaging the yarn ends during the The location inside the channel is not easy
