Embodiment Construction

[0028] In FIG. 1 , an embodiment of a spinning machine for producing cross bobbins, ie an automatic cross-winding winder, is shown schematically in side view, generally designated 1 . This automatic cross-winding winder generally has many identical working parts at its rear (not shown in the figure), which is exactly the winding head 2 in the existing case.

[0029] On the winding head 2, as is well known and therefore not described in detail here, the bobbin 9 produced by the ring spinning machine is rewound into a large roll cross bobbin 15, which when completed, is crossed bobbin 15 by means of an automatic working Auxiliary devices and preferably a cross bobbin changer (not shown) are transferred to a machine longitudinal cross bobbin conveying device 21 and conveyed to a bobbin loading station or similar device located at the end of the machine.

[0030] Furthermore, the cross-winding automatic winder 1 has a logistics device as bobbin and tube transport system 3 . In th...

Abstract

A yarn splicing device (10) used to pneumatically connect the end of two yarn has a splice channel with a compressed air inlet. The assembly has two rotating prisms (27, 28) which each turn from a thread pick-up presentation to a splice presentation. The yarn splicing device 10 has two rotatably supported prism parts (27, 28), both of which can pivot between a yarn receiving position (I) and splicing position (II). The prism parts (27, 28) are so formed that the splicing channel (44) is formed between both prism parts (27, 28) while the prism parts are in the splicing position (II).

Description

technical field [0001] The invention relates to a yarn splicing device according to the preamble of claim 1 . Background technique [0002] Yarn splicing devices for splicing two yarn ends pneumatically are known long ago in connection with automatic cross-winding winders and are described in numerous patent-claimed applications. [0003] Therefore, not only know such a kind of yarn splicing device, wherein be located at the yarn feeding gap of the splicing channel in so-called splicing head and keep not closed during the splicing process, also know a kind of yarn splicing device, In this case, the threading gap is closed by a special cover during the splicing process. [0004] For example, DE3935536C2 describes a yarn splicing device with a splicing head whose splicing channel has an almost circular cross section. The compressed air inlet leads tangentially into the splicing channel. In addition, the splicing channel also has a straight-through slot in its upper part, th...
