The invention relates to a device for producing strands of hair for wigs and artificial parting by means of twisted ones, holding the tufts of hair firmly and forming the soul Threads. The innovation is that the threads in the shape of a V with the Vertex into a resilient hook and fastened with the free ends to nuts are on revolving and revolving

ίο Screw spindles are stored in such a way that they approach each other as the threads are twisted.

The thread ends are guided in such a way that the angle which is to be twisted Include thread trough], remains the same during the entire work process. Through this get all turns the same pitch, so that the distance between the tufts of hair and the distances on which strands are to be tied in by the number the revolutions of the drive wheel can be precisely determined.

The drawing illustrates an embodiment of the new device.

Fig. Ι shows the entire device from the side,

Fig. 2 shows an opened nut from above,

Fig. 3 and 4 this nut closed in plan and side views.

5 and 6 show the device for tensioning the thread in two different ways Positions.

The drive shaft α is rotatable in the bearing b to which a ring gear c is attached. A handwheel f on the one hand and a bearing piece d on the other hand are rigidly connected to the shaft α. On the bearing piece sit two bevel gears e, e, which engage in the ring gear c , rotatably mounted and secured against axial displacement. Screw spindles g are connected to the bevel gears e, e in such a way that their axes coincide. Two-part nuts i are placed on the spindles g , which can be opened and closed around a hinge k and opened and closed by pivoting a bracket I around. In one jaw of the nuts i , hooks j for hanging the ends of the thread t are rotatably attached.

A camp j> is set up opposite camp b , which the. Receives device for tensioning the thread. This consists of a hook n which is attached to a bolt m which can be displaced in a sleeve 0. The bolt m and the sleeve 0 are secured against rotation in a known manner. A split pin q is inserted through the outer end of the bolt m. Between this split pin and the bearing φ there is one pushed onto the sleeve 0

Clamped helical spring r , which constantly presses the bolt m and thus also the hook η outwards against a lifting thumb s. By turning the lifting thumb clockwise, the bolt m can be pushed inwards while compressing the spring r.

A comb ν is arranged in front of the device.

The operation of the device is as follows:

The nuts i are first placed on the outer ends of the spindles g and closed by closing the bracket I.

Now one end of the thread t is hooked into the hook j of one of the screw nuts i , the thread is pulled through the hook η and the lifting thumb is turned clockwise so that the bolt m moves inward; then you hang the other end of the thread in the hook / the other nut and let go of the lifting thumb, the spring s pulling the hook η outwards and tensioning the two thread legs t evenly.

The tension of the legs t prevents the nuts i from rotating with the spindles g during the following process.

If you now turn the handwheel f, the spindles g are rotated by the bearing piece d in the vertical plane, and at the same time the bevel gears e roll on the fixed ring gear c so that the spindles g also rotate around themselves in opposite directions . Since the nuts i cannot turn with them, they migrate inwards while the legs t are wound around each other. The pitch of the thread of the spindles g and the bevel gears are dimensioned so that the nuts are always brought closer to one another in proportion to the progress of the winding of the legs t and the angle enclosed by them remains the same. With each turn of the handwheel f , the thread legs wind around each other by an equal distance.

If, after a certain number of revolutions of the handwheel, a tuft of hair combed out in the comb ν is pushed into the apex of the angle formed by the thread legs, it will be clamped firmly between the threads during the following revolutions of the drive wheel f. It is therefore up to you to determine the distance between the successive tufts of hair and the width of the latter by turning the handwheel accordingly, by inserting hair during a certain number of turns. In this way a consistently uniform product is achieved without any demands being placed on the skill of the worker.
