However, the magnetic rolls shown here are so-called solid rolls having no space from the roll surface to the axial center. As shown in FIG. 7, the conventional magnetic roll is arranged so that a driven roll 3 driven by a drive source 1 such as a motor is driven by a pure drive roll 2 made of a ferromagnetic material. Now, when the coils 6 and 7 are energized and the magnetic poles 4 and 5 are excited, N and S poles are generated in the magnetic poles 3 and 4, and the magnetic force lines M flow from the N pole to the S pole, so that the drive roll 2 and the driven roll 3 are Get excited. When the drive source 1 rotates the drive roll 2 counterclockwise through a rotation transmission mechanism such as a gear or a belt, the driven roll 3 is also attracted to the drive roll 2 and rotates clockwise by friction transmission. When a work 8 such as a magnetic tape is inserted between the rolls 2 and 3, it is fed in the direction of the arrow and pressed by the rolls 2 and 3.

がある。As described above, when the magnetic force lines M flow the N and S poles through the rolls 2 and 3 and rotate the rolls 2 and 3, eddy currents are generated in the rolls 2 and 3. However, for this reason, the entire roll, including the inside and the surface of the roll, generates heat. The eddy current generated in the roll is generated in proportion to the square of the rotation speed of the roll and in proportion to the electric conductivity of the material of the roll, and the braking force is generated according to Fleming's law with respect to the rotation force of the roll. Therefore, the heat generated by the eddy current not only adversely affects the work, but also causes an inconvenience of spending an extra rotational driving force for this braking force. Therefore, it is necessary to make the heat generated by the eddy current have an appropriate controlled temperature required by the work. Further, it is necessary to reduce the braking force that hinders roll rotation as much as possible.

The heat medium is press-fitted, and the heat medium reaches the second peripheral passage 12c from the second outer passage over the opening groove 18c, then passes through the opening groove 17c, and passes through the first outer passage 20b to the first outer cylinder. Reaching 20a,
It is guided to a rotary joint (not shown) through a space between the outer diameter portion of the first inner cylinder 20a and the first outer cylinder 24a, and is returned to a heat exchanger (not shown). These heat exchangers (not shown) cool (heat) the heat medium that has passed through the magnetic roll 11 and whose temperature has risen (falls), and then recirculates it back into the magnetic roll 11. In the above-described embodiment, the heat medium of the fluid is distributed to the magnetic roll 11 by a two-system circuit, that is, a circuit in which the fluid flows from the first inner cylinder 17a to the second inner cylinder 18a and the second outer cylinder 21a to the first inner cylinder 18a. The magnetic roll 1 is formed by the circuit flowing to the outer cylinder 20a.
Although the temperature control of No. 1 is shown, this is an embodiment of the present invention which is desirable when the magnetic roll 11 is efficiently and uniformly cooled by circulating the heat medium from both ends of the magnetic roll 11. It is shown, and the present invention can be implemented by passing the heat medium through other routes. Further, the material of the roll outer shell 23 is not limited to one made of only a material such as stainless steel, a silicon steel plate or a non-ferrous metal, which generates a small amount of heat by electromagnetic induction, and the outer shell surface thereof is made of an elastic material such as rubber or cotton. It is also possible to use a compounding device which is suitable for use as a so-called calendar device for coating a magnetic tape or the like with this roll. Further, some work requires a high temperature for the roll, and in such a case, it is not necessary to use a material having a low generation of eddy current as a material for the outer shell of the roll. That is, in such a case, a material that is a ferromagnetic material such as silicon steel and has a relatively high specific electric resistance (about 5 to 10 times that of low carbon iron) may be used instead. In the above-mentioned embodiment, the structure and shape of the rotary joint and the heat exchanger are well known, and therefore detailed description and illustration are omitted.

Also, since a material having a high electric resistance, such as silicon steel or stainless steel, is used as a material of a magnetic roll constituting member that constitutes a magnetic circuit such as an outer plate or a roll outer shell, it is caused by an eddy current when the magnetic roll is rotationally driven. The brake is extremely small compared to a mere iron-free roll, and the loss of rotational driving force can be suppressed to a minimum. Further, according to the present invention, since the temperature of the outer shell of the roll can be controlled by the heat medium of the fluid to be in an arbitrary temperature range, it is possible to perform the rolling at the surface temperature most suitable for the work. Furthermore, according to the present invention, as shown in the above-mentioned embodiment, the temperature of the outer peripheral surface of the magnetic roll is uniformly cooled by passing the heat medium of liquid such as liquid or gas from the left and right ends of the magnetic roll. It can be (heated).
