Improvements to double thread spindles for the production of fashionable yarns by twisting two or more yarns, and thereafter improved spindles.

The invention relates to improvements in spindles for the formation of a double wire in yarns made of synthetic or natural fibers.

The invention pursues the goal in detail, directly at the exit the spindle, which gives a yarn a double twist, fashionable yarns either by twisting a double twisted yarn with another thread or by twisting a double-twisted one

Yarn with two or more other yarns or generally through

309829/0790

Twisting two or more yarns to form.

Spindles are known that give a twine double twist. The invention is applicable to either Spindles that use a thread drawn off a plied bobbin, or on spindles that use take the yarn from the unbalanced bobbins and twist it directly inside the hollow spindle, or on Spindles that allow the yarn to run in the opposite direction (spindles for executing the Double wire for yarns with coarse denier).

According to a practical embodiment of the invention an axially extending channel is formed in a double wire spindle of a known type, which on the circumference, preferably emerges at the bottom of the plate so that the double thread emerges from the bottom of the plate and then again known technique rises, while the one or more coming from below along the axis bore The thread emerges at the edge (outside) and with the doubled thread either at the lower end of the balloon or is twisted together at its upper end.

According to the invention, the improvements are thus characterized in that means in the form of am Rapidly rotating from the bottom of the plate,

there are hollow rotating tubes that double the Take up thread, and rotating tubes for receiving the yarn or yarns to be twisted, there is the possibility of common outputs of the rotating rotating tubes. The invention is now explained in more detail on the basis of the following drawing, which also shows old and new forms of application, and which is only listed for the sake of explanation and without restriction. Show it:

Fig. 1, for example, the improvements to the spindles made by unwinding yarn from a Delivery plant, e.g. folded bobbin being unwound

Figure 2 illustrates a second possible solution, which involves twisting the yarns together at the beginning of the resulting balloon and

Fig. 3 shows a further possible form of solution for the formation of a fashionable yarn with three or more extra yarns that end up with the twisted yarn in the special case connect the balloon.

In the drawing, 1 denotes the unwinding head, which the Yarn 3 (in this case shown as a yarn cop 4 seated firmly in the center of the spindle) from the

309829/0790 -4-

folded coil or cop 4 unwinds and from there directs it into the hollow spindle, where it is in the with the plate 2 firmly connected channel enters, exiting it forms the balloon 3 ".

In the present case, the yarn 9 to be twisted enters the channel 7 from below, from which it forms a second balloon 9 ^{1 as} it emerges. This second yarn, which can be fed at the desired speed and by known means, not shown, is given a wrong turn after passing through the channel 7, which is also firmly connected to the plate 2.

The twisting, shown here in FIG. 1, between the yarns 3 'and 9' takes place in FIG. 5 at the end of the balloon.

The different twisting state of the two yarns, the supplied amount of yarn 9, apart from the twisting state, the color and the titer of the yarns produce the desired fashionable effect.

Through channel 7 or through several channels 7 ' (See example in Fig. 3) several yarns 9 can either be fed in under different or the same feed characteristics.

The yarns entering through 7 can also have the same or different twisting, dyeing, Have titer or surface features.

If desired, it is also intermittent Feeding of the yarn or yarns 9 is possible.

Furthermore, Cs-Fig. 2), the twisting is possible of the yarns 3 and 9 at the beginning of the balloon formation or of the yarn 3 and one or more yarns 9 to To let the start of bale formation and to supplement the fashionable yarn with further yarns 9, which are twisted at 5. As can be seen, there are many variants, the feature being consists of a double-twisted thread (which is unwound from the ply or unfolded bobbin) or several yarns (except for its own twisted state in the yarn) that get a wrong twist.

Claims

309829/0790

Claims (6)

Claim üche 1. Improvements to two-for-one spindles for creating fashionable yarns by twisting two or more together Yarns, the spindles pulling the yarn from a plied bobbin or bobbin fixed in the center of the spindle subtracts from two or more unfilled bobbins or where the double-twisted yarn is wound onto a plied or unfilled bobbin resting within the bell and the yarn to be twisted has its own characteristics, like titer, twist; Surface condition, color, etc. and the two yarns are the same or different May have features thereby characterized in that rotating rotating tubes (6 and 7), namely rotating tubes (6) for Receiving the base thread to be twisted and at least one rotating tube (7) for receiving the thread to be twisted Thread are present. 2. Improvements to twin wire spindles according to the previous one Claim, characterized in that the rotating tube C 6 and 7) with the rotating plate are firmly connected. 3. Improvements to twin wire spindles according to claims 1 and 2, characterized in that that the rotating tube (6) for the basic thread and 309829/0790 -7- d ± e rotating tube (7) for the twisted one with it Thread unite at the exit of the plate, 4. Improvements to twin wire spindles according to claim. 3, thereby gercennzeich.net, that there are also independent rotating tubes (7) for the twisting thread is present, 5. Improvements to twin-wire spindles after, one or more of the preceding claims, characterized in that the yarns to be twisted are fed at a constant speed, 6. Improvements to twin wire spindles according to claims 1 to 4, characterized in that the feed speeds of the yarns to be twisted are variable. 309829/0790 Blank page
