Example Embodiment

[0028] In Fig. 1, an embodiment of a spinning machine for the production of cross-packages, ie an automatic cross-winding winder, generally designated by the reference numeral 1, is shown schematically in a side view. Such automatic cross-winding winders generally have many of the same working parts at the rear of the car (not shown in the figures), in the present case the winding head 2 .

[0029] On the winding head 2, the cops 9 produced by the ring spinning frame are rewound, as is well known and thus not described in detail here, into large rolls of cross bobbins 15 which, when completed, are operated by means of an automatic The auxiliary device and preferably the cross-package changer (not shown) is transferred to a machine-longitudinal cross-package conveyor 21 and conveyed to a package-handling station or the like located at the end of the machine.

[0030] In addition, the cross-winding automatic winder 1 has a logistical arrangement as a bobbin and bobbin transport ...

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...
