Description

The proposed torsional winding machine, equipped with a device for automatic regulation of thread tension, has the peculiarity that it uses a cylinder freely mounted on the spindle, carrying a butterfly on top to coil the thread on the spool, and a brake device on the bottom. To regulate the tension of the thread inside the cylinder freely mounted on the spindle, there is a second cylinder rigidly connected to the spindle, covered by a helical spring fitted with a thumb at the upper end for passing the thread coming from the exhaust cylinders and the lower end attached to the cylinder freely attached to the spindle .

The drawing shows a longitudinal section of a torsional-winding apparatus in an exemplary form of its implementation.

The hollow 1-spindle 9 is provided at the upper end with a fine thread for attaching to the cylinder spindle /. A cylinder 2 is mounted on the sleeve of this cylinder / freely mounted, having in the lower part wings 4 for hydraulic braking and channel 5 for a brake device in the form of an adjustable spring or pellet.

In the upper part of the cylindrical space between the cylinders 1, 2, a screw spring 6 made of steel wire is freely disposed, the lower end of which is attached to cylinder 2. To improve the operation of the apparatus c. 111, it is advisable to use the spring 6 made of steel wire, the thickness of which gradually increases towards the lower end. The upper end of the spring 6 through the cutout at the upper edge of the cylinder 2 leaves the space between the cylinders and has a wing 7 at the end for passing the thread 3 coming from the exhaust cylinders and then to the coil through the cylinder 8 of the cylinder 2. At the opposite side of the cylinder 2 there can be an appropriate counterweight is attached.

Through the spindle channel 9, the spindle Yu is tightly (in grinding), which carries the coil at the upper end and rotates together with the spindle 5. The JO spindle and the spindle have a vertical reciprocating movement from the vater mechanism, etc. of the machine.

The walls and the bottom of the cylinders 1, 2 have small holes to prevent moisture accumulation. Cylinders /, 2 must be strictly balanced to avoid a beat.

Thread 5 from the exhaust cylinders goes through thumb 7 of spring b to form a balloon. Having passed through the movable lamb 7 and through the lamb 8, the already twisted yarn is wound into a spool. .

The coil — and the cylinder / rotates together with the spindle 5, and the cylinder 2, together with the sheep 7 and 5 attached to it, lags by an amount corresponding to the winding y. Cylinder 2 lags due to its braking, which gives a constant torque that is directed in the direction opposite to the rotation of the spindle, and is designed to overcome the torque from the yarn Eat at the maximum winding diameter and friction between the cylinder sleeves 1, 2. When the diameter, of the winding is less than the maximum, the additional torque for cylinder 2, directed in the direction of rotation of the spindle, causes friction. cylinder /, which requires some slight increase in thread tension. The magnitude of this friction depends, other things being equal, on the number of turns of the spring 6. The tension of the thread 7 of the lamb 7 tends to approach the wing 8 against the action of the moment of friction force of the spring 6 on cylinder I.

In the case of an increase in the tension of the thread, the lamb 7 approaches

the wing 8, the diameter of the turns of the spring 6 is reduced, and consequently, the friction of the spring on cylinder 1 increases, which reduces the lag of the cylinder 2 from the cylinder / and reduces the tension of the thread. In the case of a decrease in the tension of the thread, the reverse occurrences occur.

For an apparatus that requires a lower tension, the threads in the balloon, bar, shears 8, are made double, and the thread goes first to the lamb 8, then to the lamb 7 and again through the lamb 8 to the spool.

Lamb 7 can be attached to a ring freely rotating on the upper edge of cylinder 2. The upper end of spring 6 is also attached to the same ring.
