Problems solved by technology

[0014] However, the disadvantage of this very advantageous yarn suction device is that, with the device designed in this way, it is possible to ensure optimal application of the force in the area of ​​the suction nozzle contour even after winding interruptions due to yarn breaks or controlled cutting. suction flow, thus reliably winding the upper side yarn from the winding bobbin, when changing batches, whereby the lower side yarn originating from the yarn supply bobbin needs to be conveyed directly to the Empty tubes for winding bobbins, supplying new underside yarns by means of a suction device is somewhat complex and time-consuming
This means that with such a yarn suction device arranged at one end of a substantially closed yarn guide channel and equipped with a pivot plate, the underside yarn originating from the unwinding bobbin is correctly transferred to the newly wound bobbin ETC is relatively time-consuming and difficult

Embodiment Construction

[0034] figure 1Shown is a first advantageous embodiment of a station 1 of a textile machine for the production of cross-wound bobbins, comprising in the area of ​​its winder 4 a yarn suction device 21 designed according to the invention, the yarn suction device 21 being arranged At the end of the substantially closed thread guiding channel 6, the thread guiding channel 6 surrounds the thread path.

[0035] As is already known, textile machines for the production of cross-wound bobbins, for example cross-winding winders, usually have a plurality of identically designed stations 1 in which the yarn supply bobbins 2 are rewound in large volumes. On the winding bobbin 5, the yarn supply bobbin 2 is usually a spinning bobbin produced on a ring spinning machine, holding only a relatively small amount of yarn material, and the bulky winding bobbin 5 is usually a cross-winding bobbin.

[0036] The final cross-wound bobbin 5 is then removed by the operator or transferred to the figu...

Abstract

The invention relates to a workstation (1) of a textile machine for creating cross-wound spools. The workstation comprises a winding device (4). The winding device (4) is provided with a bobbin framework (11) installed in a pivoted way and for a rotary installation of a cross-wound spool casing pipe (40) of a winding bobbin (5), a roller (34) and a yarn absorbing device (21), wherein the winding bobbin (5) is supported on the roller (34) during winding; the yarn absorbing device (21) has an upper setting plate (22) and a lower setting plate (23) capable of being movably installed. According to the invention, the yarn absorbing device (21) has a suction opening (28) filled with negative pressure and a flexible slide member (7) configured to be controlled in a limited way and having a yarn receiving opening (20).

Description

technical field [0001] The invention relates to a station of a textile machine for the production of cross-wound bobbins, comprising a winding device having: a pivotally mounted bobbin frame for rotatably mounting a cross-wound bobbin sleeve for winding bobbins a tube; a roller on which the winding bobbin is supported during the winding process; and a yarn suction device including a movably mounted upper pivot plate and a movably mounted lower pivot plate. [0002] In an advantageous embodiment, the yarn suction device forms an end piece of the yarn guiding channel which encircles the yarn path between the unwinding bobbin and the winding bobbin during the winding process. Background technique [0003] In the station of such a textile machine (also known as a cross-winder) that produces cross-wound bobbins, the unwinding machine (for example a ring spinning machine) arranged upstream in the operating process has produced the unwound Bobbins, such as spinning bobbins, each h...
