Problems solved by technology

[0003] The disadvantage of this anti-rotational fixing of the slider is that in order to adjust the range of the drafting zone by moving the slider in the bracket, a certain gap must be left between the flat rail and the outer wall of the slider, which may be related to the machining accuracy change
This variable gap directly affects the accuracy of the parallel maintenance of the slider relative to the bracket, and further affects the parallel maintenance accuracy of the top roller on the grip frame in the drafting device relative to the corresponding matching bottom roller
The varying machining accuracy negatively affects parallelism

Embodiment Construction

[0038] exist Figure 1 to Figure 6 The view of the drawing shows the bracket 1 for the top roller support and the pressing arm of the drafting device of the spinning frame and at least one preferably U-shaped slider 2 arranged in the bracket 1, the bracket 1 is configured as U-shaped shaped part that opens downwards. The at least one slider 2 is used to accommodate and load the top roller of the drafting device and is fixedly connected to the carriage 1 during the working of the drafting device. It is generally provided that the slide 2 is displaceable along the longitudinal axis L of the carriage 1 in order to adjust the drafting range which is relevant for the function of the drafting device. Such as figure 2 As shown in the illustration of FIG. 1 , the carriage 1 has on its closed upper side recesses 6 configured as elongated holes, within which recesses 6 the slide 2 can be moved so that the drafting range can be adjusted. The movability and fixability of the slider 2 ...

Abstract

The present invention relates to an upper cylinder carrying and load arm for a stretching unit of a spinning machine. The upper cylinder carrying and load arm is provided with a U-shaped bracket (1) with a downward opening. The U-shaped bracket is internally provided with at least one slider (2, 20, 30). The slider comprises a pressuring component (5), a holding frame (3) for receiving an upper roller, and an adjustment and fixing device (4). The slider (2, 20, 30) can move along a longitudinal direction relatively to the bracket (1) by means of the adjustment and fixing device and can be fixed to the upper side (9) of the bracket (1), wherein, for fixing the slider (2, 20, 30) in the U-shaped bracket (1) without rotation relatively to a vertical axis in the fixed state, the slider (2, 20, 30) closely clings to at least one inner surface (7) of the bracket (1) with at least one selected from the side surfaces (8, 9, 21).

Description

technical field [0001] The invention relates to a top roller support and a pressing arm used for a drafting device of a spinning frame. The top roller support and a pressing arm have a U-shaped bracket that opens downward, and at least A slider comprising a pressurizing element and a holding frame for receiving the top roller and an adjustment device, by means of which the slider can move longitudinally relative to the carriage and can be fixed on On the bracket, wherein, in order to fix the slider in the U-shaped bracket against rotation about the vertical axis of the slider, the slider uses at least one side wall to cling to the bracket the inner side of the Background technique [0002] German patent DE 39 02 859 A1 discloses a top roller support and pressing arm, which is composed of two flat rails with the same structure, and these two flat rails are arranged on the end side by The spacers are connected to each other and kept parallel to each other. Between the two f...
