Problems solved by technology

However, having the ring on the spool is a disadvantage, i.e. each spool must be equipped with a ring, which is a not insignificant cost factor
Furthermore, there is still a high risk of injury as the spool must be changed frequently by the operator and the teeth can injure the operator holding it

Embodiment Construction

[0038] figure 1 A side view of the spindle 1 is shown. The cop 3 is located on the shaft 2 of the spindle 1 . Adjacent to the shaft 2 of the spindle 1 there is a clamping crown 4 . In addition, the cutting device 5 separate from the clamping crown is arranged on the clamping crown 4 , although hardly visible here, but designed to be flat and located on the clamping crown 4 . Cutting means, cutting edges, etc. are suitable as cutting means 5, as described in the examples below.

[0039] Figure 2a The clamping crown 4 is shown in more detail in the open state, as it appears shortly before the cop 3 is removed from the spindle 1 . The clamping sleeve 6 has been pulled down in the process, so that the lower winding area 7 is opened. Then, several turns of wire are wound onto the lower winding area 7 . Between the cop 3 and the lower winding area 7 , the thread travels through the notch in the clamping ring 8 and thus also over the cutting device 5 .

[0040] Then, as in ...

Abstract

The invention relates to a spindle (1) for a work station of a textile machine, in particular a ring spinning machine, the spindle (1) having a shaft (2) for accommodating a tube, the shaft (2) due to the winding the wire becomes the cop (3); and the cutting device (5, 15, 20) for cutting the wire when the cop (3) is removed from the spindle (1), wherein the cutting device (5, 15) , 20) has a cut (11) for closing the shaft (2), an inner area (12, 24) adjacent to the cut (11) and a cut-off area (10, 16, 21). According to the invention, the inner region (12, 24) of the cutting device (5, 15, 20) has at least one clamping region (13, 25) for clamping the cutting device (5, 15, 20) to the shaft (2) on. Furthermore, the invention relates to a cutting device (5, 15, 20) for cutting the thread when removing the cop (3) from the spindle (1).

Description

technical field [0001] The present invention relates to a spindle according to the application for a work station of a textile machine, in particular a ring spinning machine. The invention also relates to a cutting device and a ring spinning machine with a plurality of workstations. Background technique [0002] Ring spinning machine spindles are known, for example, from EP 911 434 B1 with a cutting device for cutting the spun yarn when removing the cop, wherein the cutting device is guided by a collar on the top of the spindle and fixed to the spindle by means of protrusions On the top of the spindle, the protrusion engages behind the groove in the top of the spindle. However, this type of fastening assumes a groove in the top of the spindle, which is known to be provided on only a few particular spindles. Therefore, the cutting device cannot be used for any other spindles. [0003] EP0292856A1 discloses an upper ring with a cut-off area and a flange. This ring is attac...
