the storage rack of the first reel of the rod 11 passes through the looping ring 4, the guide element 5, the guide roller 7 and further through the descaler 9, where it is subjected to preliminary descaling. The wire is then passed through a cleaning device 10 for final release from the remaining scale. Having passed all the stages of cleaning, preliminary and final, the wire gets on the drawing mill 13, and then on the precision machine 14.

The looper 4 on the rocker arm with the emergency shutdown unit serves to catch the loops of the tangled rod and stop the line. The guide element 5 is designed to prevent the likelihood of the wire 12 slipping from the groove of the guide roller 7 mounted on the front end of the trunk 6.

Swinging trunk 6 with counterweight 8 is blocked with an emergency shutdown assembly (not shown) and serves to turn off the line in case of excessive tension in the initial stage of winding.

 The transportation of the reels of the rod to the viewing device is provided by the drive of the storage rack.

The NIN of the calcined steel 9 U-shaped yoke 27, the adjusting screw 28 with the flywheel 33 are installed on the opposite side of the stand of the viewing device.

Having passed the pre-cleaning stage in the descaler, the wire enters the cleaning device for

final cleaning operation

The cleaning device works as follows.

The wire 12 is passed through the half-cylinder 38c beforehand, and the inner space through the receiving funnel 55 is filled with a filler 56, for example a shotgun.

At the time of filling the mouthpiece of the cleaning part 34, the actuator 35 is activated. During operation of the device, the filler 56 under the action of a pulse of inertial movement forces generated by the reciprocating actuator 35 is connected in small portions through the outlet of the tip 57 into the receiving funnel 69 of the transporting part 36. From the latter, the filling 56 through the outlet of the neck 71 enters the receiving funnel 55. Continuously cleansing medium during operation moves in a closed loop. Such a character- ation of the cleaning medium ensures an adequate density of the shot adjacent the surface of the wire being cleaned, therefore, the required quality of cleaning. The bottom of the tube 67 is perforated, whereby the cleaning fluid is free from scale during movements. Dross is poured into pallet 74.

During the next filling of the cleaning rod with a rod, it is necessary to release the mouthpiece of the cleaning part 34 by about half of the filler. For this, it is necessary in individual order to let the cleaning device work for some time. After replacing the neck 71 with

neck 88 opposite direction. Then the required amount of cleaning medium is poured into the pan

89. After filling the mouthpiece of the cleaning part 34 with a rod of metal, cleaning it. the medium from the pallet 89 is back-through the funnel 55 to the mouthpiece of the cleaning part, for which

pre-replace the neck 88 on the neck 71.

Due to the difference in the speeds of the reciprocating movement of the carriage 44, the cleaning medium receives an inertial impulse of displacements, which is achieved by the presence in the drive 35 of the clutch 63 of overtaking, the crank mechanism 66 and the return spring 52. When moving forward, the carriage 44 gets

given the speed of the drive, with the return movement of the carriage under the action of the spring 52 receives a sharp push back due to the actuation of the overtaking clutch. Thus, it turns out

difference in carriage speeds in reciprocating motion.

For effective operation of the cleaning device it is necessary that the speed of the reciprocating movement

clearing of the device, 1.5-2.0 times exceeded the speed of dragging. The technical and economic effect of the insertion of the invention is provided by an increase in productivity as compared with the known device.
