The invention relates to a two-sided two-for-one twisting machine with rows of spindles arranged one above the other, to which an equal number of winding units is assigned.

Two-for-one twisters come in a variety of designs well known. In particular, a two-sided two-for-one twisting machine has become known in which the Spindles which are driven by a single shaft that extends over the entire length of the spindle bank, arranged offset in two rows one above the other and above the two-for-one twisting spindles associated winding units are attached (German utility model 1,900,926). However, this machine still shows significant shortcomings.

It is true that they provided an improvement over the most common single-row two-for-one twisting machines machine utilization through the arrangement of the spindles in a slightly inclined position in relation to the vertical in two rows one above the other.

This arrangement of the two-for-one twisting spindles in such a way that they are essentially perpendicular or only slightly against the

Vertical inclines, however, had the very significant disadvantage that they led to considerable construction heights, which in turn made the use of auxiliary devices necessary to reach the upper parts of the machine. Another major disadvantage of the known machine construction was, that due to the special choice of the spindle drive with the large number of pulleys, an extraordinary one strong noise development was connected, which was not behind that of the widespread over the whole machine running drive with a single endless belt lagged behind and in some cases was considerably higher than the values that should be adhered to in order to avoid damage to health. Plus, changing the drive belts was great complicated and required not only the separation of the common drive shaft, but also the solution of part of the Shaft bearing in order to be able to bring the respective belt into its working position. Other disadvantages such as poor usability, Complicated thread insertion, etc. led to the fact that, despite the advantage of saving space, the single-row machine was still preferred because it was unhandy compared to the multi-row two-for-one twisting machine previously offered considerable operating advantages.

The technical problem on which the invention is based exists now in creating a two-sided two-for-one twisting machine that has increased capacity in terms of space requirements Ease of use, low, even for a worker in the middle Size without auxiliary equipment enabling work on the entire machine and a considerable reduction the noise development.

Using the modular principle known per se, the two-for-one twisting machine is assembled from individual, identically designed groups. Each of these groups consists initially of a drive housing '1, in which storage and drive 7, 8 of the individual two-for-one twisting spindles 3, 4 are housed Openings, not shown in the drawing, for the passage of the scavenging air. The housing 1 is provided with a cover 2 which allows maintenance of the spindle bearings and the spindle drive 7, 8.

As can be seen from Fig. 2, the spindles are preferably i '-. arranged in two rows 5 and 6 and staggered. In this way, the densest packing of the spindles is necessary to achieve a "= · as compact as possible.

be divided into smaller groups if this appears appropriate; However, when assembling the ¹ number of winding units 17, 19; 18, 20 corresponding to the number of twisting spindles, their combined length must correspond to the length of the drive housing 1 comprising the respective spindle group, since otherwise it would not be possible to line up individual machine units.

The individual winding units 17, 19; 18, 20 consist of known ter way of a distribution roller 17 or 18 and the take-up reel 19 or 20. According to the invention, for each side of the machine only a single pre-take-off shaft 23; 25 is arranged. These is so that the operation of the drive housing is furthest distant take-up rows are not made difficult by their arrangement will. It is therefore expediently about at the level or, better, slightly below the lower or slightly above the upper winding row, depending on whether the winding takes place below or above the two-for-one twisting spindles 3, 4.

In the drawing (Fig. 1) are on both sides of the machine two different constructions of the pre-withdrawal shaft 23; 25 are shown. On the left-hand side of FIG. 1 there is a pre-take-off shaft 23 of a type known per se below the lower winding unit 18.20 attached, in which the lead rollers sit on the shaft itself. Two pulleys 24 are required for each, in order to obtain a sufficiently large angle of looping of the thread. ·

On the right hand side of Fig. 1 is a lead roller construction according to the invention shown, in which a large wrap angle can be achieved without the arrangement of pulleys can. For this purpose, sit above or when arranged of the winding units above the two-for-one twisting spindles below a continuous drive shaft 25, which is

Drive wheels 26 is equipped, the lead rollers 27. This are either individually on a short one, on the opposite ■ The leading roller and the drive wheel 32 have lowing ends Shaft 33 'attached between the lead roller 27 and Drive wheel 32 is mounted, or one in its length approximately the distance between two obliquely superposed twin-wire twisting spindles corresponding shaft 33 carries a pre-take-off roller 27 at both ends and the drive wheel between them 32 and a bearing, not shown.

The last-described construction has with respect to the Machine complexity certain advantages, on the other hand ensures the arrangement described first, in which each overrun roller 27 is individually attached and driven, a "rectified" Thread laying process. This means that when the machine is reloaded, experience has shown that this is done very quickly must be done, when placing the thread 29,30 on the advance rollers 27 does not need to be grasped, which is when creating to one shown in Fig * 2 in the right half of the picture Dual role would be necessary. Nevertheless, it can possibly be expedient to use the latter arrangement with two advance rollers 27 to choose on a shaft 33 *

On each side of the drive housing 1, the cover 10 covers the entire side of the machine and leaves only circular recesses free, the diameter of which is approximately the same as that of the pots 9 surrounding the individual twin-wire twisting spindles 5 and 6. The covers 10 each have openings 11 at the rear upper and lower end, which enable the rear spindle parts to be observed via mirrors 12 and 13. The arrangement of the covers makes it possible> for example in the middle between the two rows of twisting spindles on a corresponding support structure 34 covered against dirt, accidental damage and visibility necessary supply lines 35 such as electrical installation _t air * ·

Thread guide (31) and deflection devices are known per se 21,22 arranged.

The coming from den'Wickeln 5 and 6 threads 29 and 30 are through appropriate thread guides 31 down to the Leading rollers 23 and 27, respectively, and passed around them via preparation rollers 20, which they in relation to their position in such a way are assigned that the threads constantly touch them regardless of the traversing; from there they run onto the Take-up spools 19 or 20. ·

In a preferred embodiment of the invention In the machine, the spindles are driven by a continuous drive shaft 33 (Fig. 3) driven from via drive belt 15 «These drive belts 15 are designed as endless belts and are set in motion by the pulleys 14 mounted on the through shaft 33. They preferably include two spindle whorls 7 and 8 on each side of the machine and also run over a tensioning roller 16 above the continuous one Wave. This tension pulley sits on a bridge that can be tilted to increase the belt tension. The bridge can be weight or spring loaded however, spring loading is generally preferred.

This design of the belt drive makes it possible to easily replace the individual belts 15 at any time from the open cover side of the drive housing 1. Only the tensioning bridge (not shown in the drawing) has to be swiveled upwards. The belt 15 loosens däclürcn And can lind easily lifted by a "new be replaced ■ ~ ^{3 'i} ^. -

In itself, the two-for-one twisting spindles 3.4 can be used on each known type driven v / ground, for example by means of tangential belts running through the entire machine, by individual spindle drive, etc. Es. however, the one described above has developed with a continuous Drive shaft 33 coupled four-spindle drive especially proven because its structure is uncomplicated and practically insensitive to interference.

In order to make the course of the belt 15 clearer the four-spindle drive is shown again alone in a perspective view in FIG. It can be clearly seen that after lifting the tension roller 16, the belt is easily stripped from the hosts 7 and 8 and then lifted upwards can be. A new belt can then be put on in the same simple manner.

In the following claims, some summarizing expressions are used that include. be defined here for clarity. "Drive" is to be understood as any possible means of driving the individual two- for-one twisting spindles. In the case of the embodiment described with reference to the drawing , the drive consists of the drive shaft section with the associated belt pulleys 14, the hosts 7 and 8, the spindles 3 and 4, the drive belt 15 and their tensioning structure 16.
