Description

Device for spinning wires, strands, ropes or the like. Object the invention is a device for spinning wires, strands, ropes and. Like., In particular for electrical engineering purposes. Such core threads often have to with threads or plied spun material made of cotton, natural, synthetic, glass silk or similar, often mechanically very sensitive materials are wound. For this are generally spinners in use in which the spun material from the supply bobbins is withdrawn and fed to the spinning point via guide means. It is in order to the spinning on the object to be wrapped as tightly as possible grant, very important that the spun material with constant tension on the spun Object runs up. So far, the supply reels have been braked for this purpose. You also have to adjust the tension in the thread of the respective, during the spinning process to make constantly decreasing diameter of the supply reel independent, a drain brake arranged between the supply reel and the spinning point.

In these spinners, the supply bobbins are removed by the withdrawal of the spinning material set in rotation. Since one cannot generally expect that the focus a wound supply reel coincides with its axis of rotation, occur in the Rotation of the coil under the action of centrifugal forces different tensile stresses in the thread. In addition, the coil bearings are additionally loaded by the centrifugal forces, thereby impairing their mobility. This circumstance also causes an increase in thread tension. One is therefore to avoid the risk of thread breaks forced to walk the path. to use high quality bearings for the coils and limit the supply on the bobbins.

A spinning head is already known in which the spinning thread passes through a radial guide member encircling the winding bobbin is unwound, which when Spinning process as a result of the effective thread withdrawal on the journal of the spinning plate rotates and is under adjustable, axial braking effect. However, this is where the thread is concerned depends on the bobbin filling. In addition, the spinning is used in this spinner more or less dense depending on the bobbin filling.

Also, a machine for making ropes has been around for a long time known, in which the supply reels are attached to discs, but in which no measures are provided to achieve a constant thread tension, so that this device for even and clean spinning of elongated Objects with threads of great mechanical sensitivity is not suitable. The difficulties outlined are eliminated by a spinning device, according to the invention by the interaction of supply spools on the spinner are arranged stationary, and braking rollers, which are designed as Scholl disks are, is excellent. In the case of such a spinning device, they have so far been the case required high-quality bearings for the supply reels and the associated ongoing maintenance away. Furthermore, it is no longer necessary to increase the supply quantity to limit the coils taking into account the centrifugal forces. Finally there is the thread the supply reel no longer needs to be turned, rather it needs to be turned upside down from the supply reel is removed, the previously associated tensile stress on the thread falls away, d. That is, the thread is removed from the supply spool with practically no tension. The constant thread tension required at the spinning point is given to the thread by an intermediate Supply reel and spinning point switched brake roller, which is designed as a Scholl disc and is braked by an adjustable brake. This constant Thread tension depends on centrifugal forces and the amount of thread on the supply spool independent. The training of the brake rollers as Scholl disks is also insofar of particular advantage than the curling movement of the thread windings Self-cleaning of the brake roller from any lint is achieved.

Scholl disks per se are used in technology, e.g. B. in wire drawing, known. These are disks that have a conical edge own, on which the turns receive a lateral thrust.

In order to be able to brake the Scholl disc as softly and constantly as possible, are they after another Feature of the invention by coal blocks, which are under adjustable spring tension, can be braked.

It is also advisable to keep the threads on their way from the clod disks to the spinning point to keep them level, on the edge of the fixed or revolving spinning nipple that attaches the strand to be spun to the axis of the top conical thread star aligns to support. This ensures that everyone The thread runs freely in the right place at the one forming on the surface of the strand finds multiple and regular helix.

The spinning nipple can also, for. B. still for stripping off any Use excess impregnating agent that has previously been applied to the strand and into which the spun material is then spun.

The spinning device according to the invention allows a uniformly thin, clean and economical spinning with surprisingly simple means to be carried out, with subsequent smoothing generally being dispensed with can. The device also makes it possible in particular to follow the supply reels to give the length-measured supply, whereby it is achieved that all coils empty at the same time if possible.

In the drawing, an embodiment of the invention is partially shown schematically in longitudinal section and partly in side view.

With 1 two supply bobbins are referred to, which are arranged according to the invention stationary on the spinning plate 2 of the rotating spinner. The threads 3 are removed overhead from the supply reels 1 , passed through bores 4 and fed to the easily rotatable brake rollers 5, which are designed as disk disks according to the invention and which are braked by adjustable brakes. The threads 3 are looped sufficiently often around the clod disks 5 and then run onto the object 7 to be spun at the same height with support at the edge of the spinning nipple 6.

The invention is by no means limited to the exemplary embodiment described limited. In particular, a larger one, in each case corresponding to the number of threads, can also be used Number of supply bobbins and discs on the spinner, distributed regularly to the spinner axis, be arranged.
