SU1185402A1 - Method of applying cordel on cable conductor - Google Patents

Description

The invention relates to cable technology and can be used to overlay plastic cordell on the conductive wires of communication cables.

The purpose of the invention is to increase the production-5 of the water content of the process of applying Cordell.

FIG. 1 and 2 are given respectively a wrapper, section A-A in FIG. 1, side view in section and from above, the first va-> 0 riant; in fig. 3 - the same, side view in section, the second option.

The wrapper in the first embodiment contains a hollow vertical spindle 1 with a stabilizing ring 2 at the end of 15 c. On the spindle 1 there is a coil 3 with a cordela 4. The wrapper has a fixed glass 5, made with double walls, i.e. has an inner wall 6 and an outer wall 7, 20

forming an annular cavity 8.

The inner wall 6 of the fixed glass 5 has vertical slots or a series of holes 9, which are evenly spaced around the circumference. 25 The outer wall 7 of the cup 5 is provided with a nozzle 10 for supplying air, made, for example, in the form of a truncated pyramid or a cone. To create a uniform pressure of air over the hell of the entire circumference of the inner wall 6 of the cup 5, the latter is eccentric with respect to the outer wall 7, and the annular cavity 8 of the cup 5 is made with a section in the horizontal plane decreasing from the nozzle 10.

The wrapper yo second variant (Fig. 3) differs from the first in that the lower part of the cavity 8 of the cup 5 is made with an annular concentric inlet 11, on which the impeller of the fan 12 fixed on the spindle 1 is mounted. The impeller of the fan 12 is made

so that the velocity pressure of the air was directed upwards into the cavity of 8 cups 5.

The proposed method of imposing Cordell as follows.

The coil 3 with polyethylene cordela 4 is mounted motionless on the spindle 1. The cordel 4 is passed through the stabilizing ring 2 and fixed on the current-carrying core. During the rotation of the spindle 1, the unwinding of the cordell 4 from the coil 3 occurs due to the combined action of the pulling force from the moving core at the point of application of the cordell 4 and the centrifugal force that rolls the cordels from the coil 3 and presses them to the inner wall 6 of the fixed cup 5.

Simultaneously with the start of rotation of the spindle 1, air is injected into the annular cavity 8 of the cup 5, whose velocity head is proportional to the speed of rotation of the winding spindle 1. The air from the annular cavity 8 passes through the vertical slits 9 of the inner wall 6 of the cup 5 and creates an air cushion that squeezes the cordel 4 from the wall 6, forming a gap between them.

Ring 2 when rotating the spindle 1, rejected by centrifugal force, also rotates and stabilizes the angle of application of cordel on the core during the operation of the wrapper.

In the wrapper in the first embodiment, the air in the cavity 8 is supplied through the nozzle 10, for example, from the duct.

In the wrapper of the second embodiment, air into the cavity 8 is supplied from below to the circular concentric inlet 11 with the help of the impeller of the fan 12.
