Problems solved by technology

Although such a marking winding is produced with sufficient stability on the circumference of the bobbin, it has in principle the disadvantage that the marking is only recognizable when the yarn is withdrawn from the bobbin
However, in order to form an outwardly visible marking immediately after the completion of the bobbin, the marking of the bobbin obtained by changing the crossing angle of the winding during the marking winding is not suitable.

Embodiment Construction

[0027] figure 1 A first exemplary embodiment of a device according to the invention for carrying out the method according to the invention is schematically shown in FIG. Only this device is shown here as an essential component for carrying out the method according to the invention.

[0028] A bobbin 2 is supported on a bobbin holder 3, around which a bobbin 1 is wound. The bobbin holder 3 is designed as a driven spindle 4 . For this purpose, the spindle 4 has a clamping device (not shown in the figure) on the circumference in order to fix the bobbin 2 fitted onto the spindle 4 . The drive for the spindle 4 is not shown in the figure.

[0029] A rotatably mounted pressure roller 5 is arranged upstream of the spindle 4 along the yarn flow. The pressure roller 5 or the spindle 4 is movably supported in order to be able to gradually enlarge the bobbin 1 during the winding of a yarn 18 . The pressure roller 5 is in close contact with the circumference of the bobbin 1 during th...

Abstract

The present invention relates to a method for coiling bobbin and a device thereof, wherein the yarn is guided repeatedly before doffing on a rotating-driven bobbin in a transverse stroke. Furthermore the yarn is coiled with a cross winding until a final diameter of bobbin is obtained. The yarn is doffed on the circumference of bobbin before or after obtaining the final diameter. For keep a stableand visible mark on the bobbin as possible, the yarn is coiled with a transverse stroke with at least one shortened side in the coiling process of cross winding and / or mark winding for preparing a marking step on one end plane of bobbin according to the invention. In this aspect, the invention also relates to a bobbin which is provided with a surrounded mark step on at least one end plane for marking.

Description

technical field [0001] The invention relates to a method for winding bobbins according to the preamble of claim 1 , a device for carrying out the method according to the preamble of claim 9 and a device according to the preamble of claim 9 . A bobbin according to the preamble of claim 13 . Background technique [0002] In the production, further processing and final processing of textile yarns in several process steps, it is known to wind the yarn into bobbins between the individual process steps for storage purposes. The bobbin wound up in a preceding process is then fed into the subsequent process as a feed bobbin. It is necessary for this that the specified requirements of such bobbins are sufficient for subsequent processes, which may include, for example, a quality class or a minimum amount of yarn per bobbin. In order to be able to sort such bobbins already after they have been wound, it is known to wrap the bobbins with a marking for characterizing the bobbins. [...
