Abstract

PURPOSE:To perform an accurate calendering process by using the 1st columnar metallic roll and the 2nd metallic roll which is covered with an elastic material except for an area where a magnetic recording medium passes through and set beside the 1st roll. CONSTITUTION:A metallic roll 2 has a recessed area as its center part since the elastic matters 3 are provided at both ends of the roll 2. A magnetic recording medium is put through said recessed area and rolled with pressure together with a metallic roll 1. Thus a calendering process is carried out to obtain the smooth surface of the magnetic recording medium. Both rolls 1 and 2 get close to each other in a calendering mode and the recording medium is pressed between both rolled to be rolled out. Both elastic materials 3 don't support all pressure of both rolls and support the pressure via the recording medium even though both materials 3 are deformed with mutual approximation between both rolls 1 and 2. This ensures accurate calender processing.

Description

【発明の詳細な説明】 産業上の利用分野 本発明は磁気記録媒体の製造に使用されるカレンダー装
置に関する。DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a calender device used in the manufacture of magnetic recording media.

従来の技術 従来のこの種のカレンダル装置は、例えば特開昭５６−
１１７３３５号公報に示されているような構造となって
いた。BACKGROUND OF THE INVENTION A conventional calendaring device of this type is disclosed in, for example, Japanese Patent Application Laid-Open No. 1986-
It had a structure as shown in Publication No. 117335.

すなわちメタルロールと弾性ロールを使用して表面平滑
化処理であるカレンダーを実施していた。That is, calendering, which is a surface smoothing process, was carried out using metal rolls and elastic rolls.

発明が解決しようとする問題点 ところが、このような構造のものではカレンダーのかか
り具合に限度があった。その理由は両ロールの接触する
部分で弾性ロールが変形してしまうことで圧力が変動す
ることが原因と考えられる。Problems to be Solved by the Invention However, with such a structure, there is a limit to how far the calendar can be applied. The reason for this is thought to be that the pressure fluctuates due to deformation of the elastic roll at the part where both rolls come into contact.

そこで、本発明はカレンダーが確実に実施できるように
するものである。Therefore, the present invention enables the calendar to be implemented reliably.

た第２の金属ロールとにより構成したものである。Means for Solving the Problems and Technical Means of the present invention for solving the above problems include a cylindrical first metal roll, a first metal roll that is covered with an elastic material except for a portion through which a magnetic recording medium passes; It is composed of one metal roll and a second metal roll attached thereto.

作　　用 この技術的手段による作用は次のようになる。For production The effect of this technical means is as follows.

ダ一時のメタルロール同志の接触を防ぎ、メタルロール
のたわみを減少させ、従ってカレンダーが確実にかかる
こととなる。That is, when calendering is performed between metal rolls, the rotation of the metal rolls and the accompanying heat generation causes deflection in the contact portion, making it difficult to calender properly. Therefore, in order to achieve good calendering performance between the metal rolls, one side of the metal rolls is covered with an elastic material except for the part where the magnetic recording medium passes through, thereby preventing the metal rolls from contacting each other during calendering. Decreases deflection and therefore ensures reliable calendering.

実施例 以下本発明の一実施例を添付図面にもとづいて説明する
。図において１と２はメタルロールである。３はメタル
ロール２の両端を覆った弾性体である。EXAMPLE Hereinafter, an example of the present invention will be described based on the accompanying drawings. In the figure, 1 and 2 are metal rolls. 3 is an elastic body that covers both ends of the metal roll 2.

メタルロール２の両端に弾性体３があることにより中央
部に凹所が出来る。そこでとの凹所に磁気記録媒体（図

ることにより磁気記録媒体の表面平滑化処理であるカレ
ンダーを実施する。Since there are elastic bodies 3 at both ends of the metal roll 2, a recess is formed in the center. There, a magnetic recording medium (not shown) is passed through the recess and rotated together with the metal roll 1 under pressure to carry out calendering, which is a surface smoothing process for the magnetic recording medium.

カレンダ一時には両ロール１，２が接近することで磁気

近することで変形することが　′あっても両ロール１．
２の圧力をすべて支える訳ではなく磁気記録媒体により
圧力を支えるかっこうとなっている。従ってカレンダー
が確実にかかることとなるのである。At the time of calendering, both rolls 1 and 2 come close to each other, so that the magnetic recording media come into contact with each other, are pressurized by rolls 1 and 2, and are fed out one after another. Even if the elastic bodies at both ends are deformed when both rolls 1.2 come close to each other, both rolls 1.
It does not support all of the pressure in 2, but the pressure is supported by the magnetic recording medium. Therefore, the calendar will definitely be used.

果は大なるものがある。Effects of the Invention The present invention ensures the calendering of metal rolls.By covering both ends of one metal roll with an elastic material, the calendering is applied reliably and the surface of the magnetic recording medium is made uniform. The characteristics of the recording medium can be made stable with little variation, and this has great practical effects.
