Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a support rod for attaching a drafting device to a spinning machine such that the drafting device has a support and can be attached to the support rod with the support, and the spinning frame has a roller stand. Regarding

[0002]

It is known to utilize support rods to attach drafting equipment to spinning machines. The known support rod is formed such that it is bolted to a slider mounted on the roller stand of the spinning frame. At least theoretically, the slider is slidable with respect to the roller stand, and its position is adjustable. The support of the draft device is attached to the upper surface of the support rod.

[0003]

In such a conventional apparatus, mounting and adjusting the support, the support rod, the slider, and the roller stand of the draft device on the spinning machine are very troublesome and expensive. Since the support rod must be bolted to the slider and the slider must be bolted to the roller stand, structural space problems are associated with the large span in the drafting device when locating the mounting bolts.
Furthermore, tolerances are added during assembly, resulting in poor accuracy.

Conventionally, this problem has been partially solved by integrating a slider with a roller stand and bolting a support rod to the slider. The roller stand with integrated slider is made as a die cast part. However, the roller stand made by integrating the slider does not provide flexibility when forming a gap between the support of the drafting device and the roller stand of the spinning machine. Moreover, die cast parts often have strength problems.

It is an object of the present invention to form the connection between the support of the drafting device and the roller stand of the spinning machine in such a way that the abovementioned drawbacks are eliminated.

[0006]

According to the invention, this object is achieved in that the support rod is extended towards the roller stand so that it can be mounted directly on the roller stand.

[0007]

The function and effect of the invention can be complemented by the function of the conventional slider by directly installing the support rod on the roller stand. With such an arrangement only a few parts are required to attach the support to the roller stand. Since the support rod is attached directly to the roller stand, only a fixing means between the support rod and the roller stand is required. Therefore, there is no structural space problem and the total tolerance is small.

The use of the support rod according to the invention also has the advantage that the roller tonds can simply be made universally and on which various support systems can be mounted. The installation of the extended support rods also has an advantageous effect on the strength of the support rods, which results in less bending and twisting of the support rod.

German Patent Application No. 434273
Supports such as those described in No. 3 are anchored to the support rods by residual stresses while avoiding the adjustment mechanism. This allows the support to be easily releasably attached to the support rod and the support rod extended.

The support rod can be attached to the roller stand by various methods. In order to mount the support rod on the roller stand in a releasable and possibly slidable manner, it is advantageous to provide the support rod with a hole through which a bolt is passed.

Alternatively or additionally, recesses are also provided at both ends of the support rod. These recesses make it possible to arrange a bolt between the two support rods, which is pressed against the support rod, for example via a shim plate, so that the support rod is rigidly connected to the roller stand.

The support rods are made in various heights in order to vary widely the spacing between the support and the roller stand. In principle, it is also possible to compensate for height differences by means of shim plates or spacers between the support rod and the roller stand.

The support rod can easily be manufactured from an extruded profile and can have skirts or ribs mounted thereon or integral with it as extensions.

Embodiments Embodiments shown in the drawings will be described in detail below.

The draft device 10 shown in FIG. 1 is connected to a spinning machine via a support rod 11. FIG.
Only the roller stand 12 is shown for the spinning machine. The draft device 10 mainly includes a lever 13 and a holder 1.
4, consisting of load elements 15, 16, 17 and support 18. The draft device 10 is attached to the support rod 11 via a support 18.

In FIG. 2, the support 18 and the roller stand 1 are shown.
The bond structure with 2 is shown in detail. The support 18 has a substantially semicircular shape on the lower side, and is in contact with the support rod 11. Support rod 1 in the transition range of both
1. A plurality of stopper projections 19 that cooperate with the support 18
A, 19B and 19C are provided. The support rod 11 has, on the lower side, two extensions 20A and 20B that are tapered toward the roller stand 12. To attach the support rod 11 to the roller stand 12, bolts 21 (shown in dashed lines) are threaded through the stepped vertical holes 22 in the support rod 11.

Instead of bolting the vertical hole 22, the bolt 21 can be provided between the two support rods 11. For this purpose, it is advantageous for the end face of the support rod 11 to have a semi-circular recess in which the bolt 21 can pass.
