Problems solved by technology

[0003] The disadvantage of this anti-rotational fixing of the slide is that, in order to adjust the draft zone range by moving the slide in the carriage, a certain clearance must be left between the flat rail and the outer surface of the slide, which may be incompatible with the machining Accuracy varies with respect to
This varia...

Embodiment Construction

[0044] exist figure 1The view in FIG. 1 shows a bracket 1 for the top roller support and pressure arm of the drafting device of a spinning frame, which is designed as a U-shaped profiled part that is open to the bottom. The carriage 1 is equipped with at least one slide 2 for receiving and loading the top rollers. The slider 2 is fixedly connected with the bracket 1 during the working of the drafting device. It is usually provided that the slide 2 is displaceable in order to adjust the drafting range which is relevant for the function of the drafting device. The movability and fixability of the slider 2 on the carriage 1 is realized by adjusting means 4, such as bolts, in order to fix the slider 2 in a defined position. The slide 2 comprises a pressing element 10 and a grip frame 3 for receiving the top roller.

[0045] In operation, the pressing element 10 applies a pressing force to the upper roller, which is transmitted from the cradle 3 to the upper roller. Furthermore...

Abstract

The present invention relates to an upper roller supporting and pressurizing arm used for a drafting device of a spinning machine. The upper roller supporting and pressurizing arm is provided with a U-shaped bracket (1) that is open downwards. The U-shaped bracket (1) is internally provided with at least one slider (2) which comprises a pressurizing component (10), a holding frame (3) for receiving the upper roller, and a regulating device (4). The slider (2) can move along a longitudinal direction relatively to the bracket (1) by means of the pressurizing component (10) and can be fixed at the upper side (9) of the bracket (1), wherein, for fixing the slider (2) in the U-shaped bracket (1) with a rotation prevention mode relatively to a vertical shaft, a contact surface (8) of the slider(2) has a surface structure (6) which is jointed with a surface structure (5) that is correspondingly matched with the inner surface of the upper side (9) of the bracket (1) for obtaining shape matching.

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 opened downward, and at least one a slider comprising a pressing element and a grip frame for receiving the top roller and an adjusting device, by means of which the slider can move longitudinally relative to the bracket and can be fixed on the on the upper side of the bracket. 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 of identical construction, which are connected to each other by spacers arranged on the end sides and are connected to each other. keep parallel. Between the two flat rails, a slide with a gripping frame for receiving the top roller and a pressure element are arranged. The slide can be moved longitudinally between the flat rails in order to set different dra...
