Embodiment Construction

[0034] In the following description of the alternative embodiments, the same reference numerals are used for identical and / or at least similar features of technical solution and / or operating principle. Unless otherwise stated, the technical solutions and / or working principles of these features are equivalent to the technical solutions and working principles of the previously described features.

[0035] figure 1 is a schematic diagram of a longitudinal section of a spinning machine, in particular a ring spinning machine with a compression device 20 . Several components of the spinning machine, namely the drafting device 2 and the spinning device 10 are schematically shown in the figure. The drafting device 2 is composed of three roller pairs: an input roller pair 3 , a belt roller pair 4 and an output roller pair 5 . The delivery roller pair 5 is formed by a delivery top roller 6 and a delivery roller 7 . The two rollers of a roller pair abut together and form a pinch point...

Abstract

The invention relates to a drawing frame for a spinning machine for drawing a fiber composite (8), comprising top and bottom rollers and a loading arm (19) on which the top rollers of the drawing frame (2) are mounted, an output roller pair (5) which is formed by an output top roller (6) and an output cylinder (8) arranged thereunder, and a pneumatic compaction device (20) arranged downstream of the output roller pair (5) of the drawing frame (2) for compacting the drawn fiber composite (8) having a suction tube (17) which can be subjected to suction. The suction tube (17) is mounted on a bearing shell (25) and the bearing shell (25) is mounted on the output cylinder (7). In a compaction device for a drawing frame having a suction tube (17) which can be subjected to suction, the suction tube (17) is mounted on a bearing shell (25) and the bearing shell (25) is provided to be mounted on the output cylinder (7).

Description

technical field [0001] The invention relates to a drafting device for a spinning machine for drafting a fiber assembly, with a top roller and a bottom roller, with a load arm on which the top roller of the drafting device is arranged, with The pair of output rollers is composed of the output top roller and the output roller arranged below it, and has a pneumatic compression device for compressing the drawn fiber assembly downstream of the output roller pair of the drafting device, the compression device With a suction tube that can be sucked, and to a compression device for a stretching device with a suction tube that can be sucked. Background technique [0002] A drafting device for a spinning machine comprises at least two roller pairs, between which the fiber assembly (Faserverband) is drafted based on the different rotational speeds of the roller pairs. In the case where the drafted fiber aggregate leaves the drafting device after a pair of rollers and is sent to the sp...
