The housing recess is formed ⁿ a covering object, such as harness ilitruboprovod. Two gears (satellites) 7 are installed inside the housing with the possibility of rotation around their axes, the distance between which is greater than the cutout and the housing.

The gearbox consists of a housing 8, a rotary gear 9 and a removable drive roller 10 mounted on a lever. A drive roller with a worm 11, a distribution axis 12 with a worm gear 13, a gear 14, a worm 15 and a roller 16 with a worm gear 17 are mounted rotatably around their axes in the housing; The drive roller with the worm 11 is connected to the output axis electric motor 2 with coupling 18.

In the housing 19 of the rotary gear of the gearbox 3, mounted on the roller 16 with the possibility of rotation around the latter, there are gear 20, gear 21 and gear 22 rigidly mounted on the roller 16.

At the output end of the axis of the gear 22, a removable drive roller 10 is attached. The housing 19 is mounted on the bracket 5 with a nut 23.

The impeller 4 is made! ’The cutout is identical to the cutout of the housing 1 and; the crown of the internal gear gear. Brackets 24 are mounted on the impeller, the axes of which are mounted with the possibility of rotation of the bobbin 25 in the form of coils with a tape.

The elbow consists of an arm 26 mounted on the housing 1, and the elbow 27 itself, which is mounted on the arm 26 for rotation around the axis 28 and secured with a nut 29. A support roller 30 is mounted on the elbow 27 on the axis 31.

A handle 32 is mounted on the engine 2, on which there is a control lever 33 and wiring 34.

The tape winding device operates as follows.

Coils of protective (winding) material, for example, tape 35, are mounted on the bobbins 25. The impeller 4 is turned until its cutout is aligned with the cutout a of the housing 1, after which the device is mounted on an object, for example, a tourniquet or pipeline Зб, in a position in which the cutouts a cover his. The level v • 4 of the installation relative to the object is regulated by turning the gear 9 and the knee 27 with fixing with nuts 23 and 29, respectively. "

Replaceable air roller 10 should have a diameter j t · Lr.k.

^d ep - mm, where ^ t is the winding pitch in mm; Lrk. ” impeller revolutions per minute;

° b ° Company of the leading roller per minute.

The ends of the winding material (flax * 5 thou) are attached, for example, glued, to the initial boundary of the winding of the object - a bundle or pipeline. By pressing the control lever 33, the engine 2 is turned on, the shaft rotation of which is 2 ° through the coupling 18, the worm 11 and the worm wheel 13 of the gearbox 3 are transmitted in two directions:

-through gear 14 and satellites 7 on the impeller 4;

-through the worm 15 and the worm gear 17, the gears 20,21 and 22 of the rotary gear 9 on a removable drive roller 10. ¹

3 ° When the impeller 4 rotates, two bobbins rotate around the object. 25, on the axes of which loops of protective material are freely mounted. la for example PVC insulation tape

3S 0.20. In this case, the protective material wraps around the object, and due to the translational movement of the device at the appropriate speed from the rotating interchangeable drive roller 10, a winding with a specific step (t) takes place. The tension of the tape during winding is realized due to the friction of the bobbins 25 about the axis of the brackets 24.

<5 The technical solution allows you to: reduce material and monetary costs for the work of applying protective material to electrical harnesses, cables and pipelines, including with 50 branches, due to the elimination of the need for their dismantling; reduce the cost of the device and reduce its dimensions while ensuring stable quality and high productivity of wrapping operations due to the use of leading rollers of different diameters instead of gearboxes.
