Problems solved by technology

[0012] However, the pin strip known from EP 0 398 415 A1 is not only relatively expensive to produce, but also not entirely convincing in practice.

Embodiment Construction

[0028] figure 1 A station 2 of a textile machine for producing cross-wound bobbins, which in this exemplary embodiment is a so-called automatic cross-winding device 1 , is shown schematically in side view. As is known, such automatic cross-winding devices 1 usually have a large number of such stations 2 of the same type arranged side by side. As is also known and not further explained, at these stations 2 the spinning packages 3 produced on the ring spinning machine are rewound into bulky cross-wound packages 5 .

[0029] After the cross-wound bobbin 5 has been produced, it is handed over to the cross-wound bobbin conveyor 7 arranged in the longitudinal direction of the machine by means of a (not shown) automatically working service unit (preferably a cross-wound bobbin changer) and then conveyed To the bobbin loading station set on the end side of the machine, etc.

[0030] As shown in the exemplary embodiment, such an automatic crosswinder 1 usually also has a supply devic...

Abstract

The invention relates to a suction nozzle for a workstation of a textile machine which produces crosswound bobbins. The suction nozzle has a suction port for the pneumatic picking of a yarn breakage or a controlled thread cut accumulated on the surface of a cross-wound bobbin end. The suction port is provided with a comb strip for fixing the bobbin end. The comb strip (19) is produced by a photo-chemical etching process and formed with large and small teeth (20, 21) of different heights. The large teeth (20) with a height (H) alternatively appear with the small teeth (21) with a height (h).

Description

technical field [0001] The invention relates to a suction nozzle according to the preamble of claim 1 for a textile machine station for the production of cross-winding bobbins. Background technique [0002] In connection with the operation of textile machines for the production of cross-wound bobbins, in particular automatic cross-winders, it has always been common that in the event of winding interruptions, e.g. In the case of changing the feeding bobbin, the automatic device for yarn connection of the station itself is activated by the station computer. [0003] That is to say, as described in DE 40 05 752 A1, the workstation computer is responsible for initially placing the so-called suction nozzle with its suction opening on the surface of the winding bobbin slowly rotating counter to the winding direction and applying a negative pressure. Here, the suction nozzle attempts to pick up, with its suction opening, the yarn end of the upper yarn pneumatically from the surfac...
