The invention relates to process equipment for isolating the working chambers and inputs of powerful plasma torches and can be used in electrical engineering.

The purpose of the invention is to increase productivity.

FIG. 1 shows the device a general view; in fig. 2 shows section A-A in FIG. 1, along a guide roll with a changing curved surface

The device contains the delivery cassettes 1 with ribbons 2, which are drawn through the guide roller 3 and the guide roller with a curvilinear surface 4, and then are wound on the mandrel 5 with the drive.

A main supply system for the working fluid 6 fits the guide roll with a curvilinear surface, from the distribution-controlled system 7 and the power supply 8

The guide roller with a curvilinear generatrix is a set of annular sealed chambers 9 and anti-friction gaskets 10 between them in a closed cavity 11. Moreover, from the ends, the closed cavity is attached to the cheeks 12, and the cheeks screwed on the axis 13 are secured by turning the lock nuts 14.

The curvilinear forming surface 4 of the guide roll is made in the form of a shell made of an elastic composite material, for example, rubber, reinforced with a springy mesh, inside which annular sealed chambers 9 are made of an elastic material, for example rubber, all the elementary chambers in the axial direction are arranged sequentially on the axis from the inside they are adjacent to the curvilinear generatrix of the surface, and are also separated by cheeks with antifriction pads, each elementary sealed chamber is connected to a power source comprising a working fluid, such as gas, with the possibility of adjusting the pressure.

The device works as follows.

Electrically insulating tape material 2 is unwound from cassettes 1, about 0.

goes through the guide roller 3 and the guide roller 4 with a curved surface, then to the rotating mandrel 5 "

Along the axis of the wound product, winding cartridges are installed, the axes of which are parallel to the axis of the mandrel. The axes of the guide rolls are also parallel to the axis of the mandrel, but the roll with a curved surface does not rotate around its axis.

To create the required pressure or cavity in any part of the length of the wound product, it is necessary to create pressure in a ring 9 on a roll with a curvilinear surface according to a predetermined program. This can be done by varying the pressure of the working fluid by the distribution-controlled system (PPC) 7 in the respective branches of the main system supplying the working fluid 6.

The dimensions of the chambers vary according to the shape of the product being wound. The tapes 2, the passage along such a curvilinear section, on the winding product, respectively, either overlap or diverge, forming any given design of the product within the length of the mandrel 5.
