工程に供せられる。 FIG. 1 shows an outline of a magnetic recording medium manufacturing apparatus according to the present example, in which a support 1 wound around a source roll 2 is shown.
are conveyed to the magnetic paint application means 3 to form a coating film containing magnetic particles. Here, 3a is a coating roll. After applying the magnetic paint, the paint film is subsequently passed through a drying section 4 to dry it to form a magnetic layer, and then transferred to one of a plurality of calender sections 7-1 and 7-2 consisting of a combination of calender rolls 7a. It is guided to one side (7-1 in the drawing), subjected to calender treatment, and wound onto a winding roll 22. The thus manufactured magnetic recording medium is subjected to the next slitting process (not shown) or punching process into a disk shape.

変化させることができる。 What should be noted in FIG. 1 is that when one (7-1) of the plurality of calender parts 7-1, 7-2 is used, the support 1 is
(The reverse is also possible, and the bypass of the support 1 is shown by a broken line.) The calender part, which is not used, is thoroughly cleaned and inspected during that time. It is designed to be applied to Therefore, when cleaning the calender section, the application section 3 and drying section 4
There is no need to stop the line at all (or the downtime can be significantly reduced).
A high operating rate can be maintained. Moreover, this can be achieved with a simple configuration. In other words, 1 in the figure
0, 11, and 12 are splicers arranged before, after, or in the middle of each calender section, and these splicers cut the support film 1.
By performing film pasting such as gluing, the path of the film 1 can be selectively changed from a solid line to a broken line or from a broken line to a solid line.

ダー処理される。 In the apparatus according to this example, only one calender section 7 is installed at the latter stage of the coating/drying line, splicers 10 and 12 are provided before and after the calender section 7, and the film 1 passing therethrough is changed from a solid line to a broken line. During this time, the calender section can be sufficiently cleaned without stopping the coating/drying line. However, the support 1 guided through the bypass as shown by the broken line is directly wound onto the roll 22 and then calendered later by another calender device (not shown).

構成にて実現できる。F. Effects of the Invention As described above, the present invention selectively uses the first pass in which the support passes through the calender section and the second pass in which the support is guided outside the calender section. While being guided through the second pass, cleaning, inspection, and other measures can be taken on the calendar section. Therefore, there is no need to stop the coating line (or the stopping time can be significantly reduced) when cleaning the calender section, etc., so the operating rate can be maintained at a high level. Moreover, this can be achieved with a simple configuration.
