Problems solved by technology

[0010] A disadvantage of the method according to DE 10 2012 016 853 A1 and such a winding station is that the procedure is very complex and expensive, since each first suction nozzle located at each separate winding station must be divided into two, and the head of the suction nozzle The parts must be rotatably mounted and must be provided with respective drives

Embodiment Construction

[0042] figure 1 An automatic winder generally indicated with the reference numeral 1 , which in the exemplary embodiment is a cross-winder winder, is schematically shown in side view. Such winders 1 generally have a plurality of similar stations, also called winding stations 2 , between their (not shown) end frames.

[0043] In said winding station 2 , the bobbin 9 produced on the ring spinning machine is rewound into a large package cross-wound bobbin 15 , as known and thus not described in greater detail. The bobbin 9 is thus the unwinding bobbin from which the yarn 50 is unwound. The cross-winding bobbin 15 is formed as a winding bobbin on which the yarn is wound.

[0044] After the bobbins have been produced, the cross-wound bobbins 15 are transferred to the longitudinal cross-wound bobbin conveyor 21 by means of an automatically operated service unit, preferably a (not shown) cross-wound bobbin changer, and conveyed to A bobbin supply station or similar device at the e...

Abstract

The invention relates to a method for connecting an upper thread and a lower thread at a winding station of a winding machine, as well as a winding station for carrying out the method. According to the invention, a first suction nozzle (12) has a rear-side guide contour (45) for guiding the lower thread (55) received by a second suction nozzle (25) and held before the thread connecting device (10), and a control device (29) is designed to drive the second suction nozzle (25) and the first suction nozzle (12); the rear-side guide contour (45) of the first suction nozzle (12) moves the lower thread (55) to a yarn connection device (10) to form a coil, until the upper thread (52) is captured by a yarn guide component to be placed in the yarn connection device (10); then the first suction nozzle (12) and the second suction nozzle (25) are controlled to rotate from two suction nozzle pivots to a primary position; the first suction nozzle (12) can release the lower thread (55) in a controlled manner at the latest during the run-up of the reel drive, thereby loosening the formed thread loop.

Description

technical field [0001] The invention relates to a method for joining a top yarn connected to a winding bobbin and a bottom yarn connected to an unwinding bobbin at the winding station of a winding machine, wherein the first suction nozzle is positioned during the winding process Because the suction slot of the first suction nozzle is in the initial position in the area of ​​the winding package, after the yarn breaks in winding, the top yarn from the winding package is caught, received and supplied to the yarn by means of the first suction nozzle connecting device, and the ground yarn is caught, received and also provided to the yarn connecting device by means of the second suction nozzle, and subsequently, the two yarn ends are connected to each other through the yarn connecting device, and also involves the method for performing the The winding station of the automatic winding machine of the method. Background technique [0002] At the winding station of the automatic wind...
