である。 Recently, amorphous metal ribbons have been frequently produced by a molten metal quenching method. A schematic diagram of the single roll method, which is one of the typical manufacturing methods, is shown in FIG. According to this one-roll method, the master alloy of metals and alloys is melted in a crucible and maintained at an appropriate temperature, and then the pressure inside the crucible is increased to transfer the molten metal into a slit-like hole. A nozzle sprays onto the outer circumferential surface of a metal roll rotating at high speed. The molten metal coming out of the nozzle is stretched by rolls,
Then, it is rapidly cooled and made into a thin plate. After the thin plate rotates with the roll, it is forcibly peeled off from the roll by a gas jet, magnetic peeling, or other method. The thin plates thus produced will accumulate on the floor unless they are rolled up. When a large number of thin plates are produced continuously, a large amount accumulates, and it takes an extremely complicated process to turn it into a coil for the next process.
Therefore, it is extremely important to directly wind up the film on a winding device other than the cooling roll after peeling it off. For this purpose, a device as shown in FIG. 2 has been devised, and attempts have been made to directly wind the material. That is, the thin plate stuck to the cooling roll is peeled off, and at the same time, it is wound magnetically, mechanically, or by other methods around a take-up roll that rotates at approximately the same circumferential speed as the cooling roll. This is a method of winding up the continuous thin sheet that is being produced.

合には、ゆる巻きになる等の事故が多かつた。 However, according to the conventional winding method described above, it is difficult to make the circumferential speeds of the cooling roll and the take-up roll exactly the same. If the circumferential speed of the take-up roll was slower than that of the cooling roll, there were many accidents such as loose winding of the ribbon.

新規に発見して、本発明をなしたものである。 In other words, by connecting the take-up roll and the motor that drives it with a magnetic coupling, the take-up roll is rotated at a constant torque, and the thin strip is wound up in an extremely stable manner. can be rolled up, and
The present invention was made based on the new discovery that the shape of the coil after winding becomes orderly.

ができた。Example Using an apparatus as shown in FIG. 3, an Fe-based amorphous ribbon was produced by a single roll method. At this time, the diameters of the cooling roll and the winding roll were 500φ and 250φ, respectively. The cooling roll was rotated at 1000 rpm, and the rotation speed of the drive motor for the take-up roll was set to 2400 rpm.
Then, the take-up roll and its driving force motor were connected with a magnetic cut-off spring. First, the cooling roll and take-up roll are brought into contact,
After the mutual rotational speeds were completely matched, the contact was released, and immediately after that, the molten metal was spewed out, the production of the ribbon was started, and the winding was started. The take-up roll attempts to increase the rotation speed with constant torque toward the set value of 2400 rpm, but it remains at 2000 rpm due to the torque from the ribbon. In other words, a constant tension is applied to the ribbon as it is wound up. As a result of this experiment, it was possible to wind it up in an extremely orderly manner without cutting it.

The engineering opinion of this invention is great.
