Embodiment Construction

[0036] FIG. 1 shows a sealing area V known in the prior art for the mechanical sealing of a (not shown) fiber strip coming from a drafting device. The sealing is achieved by a fixed sealing device 1, which is arranged between the delivery roller 2 and the delivery roller 3 of the drafting device and the delivery roller 7 and is attached to the delivery roller due to the magnetic attraction of the permanent magnet 6 7 on. The sealing device 1 comprises a lower open sealing chamber 4 and is supported on a stationary shaft 5 of a delivery roller 3 . Furthermore, the sealing device 1 is pressed against the output drum 7 by means of the permanent magnet 6 (see also FIG. 2 ). Instead of permanent magnets, it is also possible to press the sealing device 1 against the delivery drum 7 , for example by means of springs or load-operated devices.

Abstract

The invention relates to a sealing area arranged downstream of a drafting device of a spinning machine, the sealing area includes an output roller (37) and an output pressure roller (32) of the drafting device, and a sealing chamber (34) with a lower opening The sealing device (31) and the delivery pressure roller (33) driven by the output roller (37) of the drafting device, wherein the lower opening type sealing cavity (34) of the sealing device (31) is loosely attached to the output roller (37), and the sealing device is supported on the shaft (35) of the delivery pressure roller (33) by means of at least one leading edge (313), wherein the at least one leading edge (313) of the sealing device (31) is defined by α< The angle of 90° intersects the line (30) extending through the center point (311) of the delivery nip roller (33) and the center point (312) of the output roller (37).

Description

technical field [0001] The invention relates to a sealing zone arranged downstream of a drafting device of a spinning machine. Background technique [0002] In the current state of the art, in order to increase the strength and reduce the hairiness of the yarn to be spun, the sealing zone of the fiber sliver is arranged downstream of the drafting device of the ring spinning machine. The sealing of the fiber strip can be achieved mechanically or pneumatically before the fiber strip from the drafting device is spun into finished yarn. A rather simple sealing zone for a mechanical seal is produced, for example, by arranging delivery pressure rollers downstream of the delivery pressure roller of the drafting device, wherein the two pressure rollers are supported, for example, on a delivery roller and A sealing device is arranged between the roller and the delivery pressure roller, which is pressed towards the delivery roller, usually by means of magnets or elastic forces. The ...
