この発明は、ビデオテープレコーダ、テープレ
コーダ等の音響機器の回転部分に用いられる摺接
部材の製造方法に関するものである。DETAILED DESCRIPTION OF THE INVENTION [Field of Application in the Acid Industry] The present invention relates to a method of manufacturing a sliding contact member used in a rotating part of an audio device such as a video tape recorder or a tape recorder.
テープレコーダの回転ヘツドスキヤナにおける
回転シリンダ（回転ドラム）の芯触れを防止した
り、テープ供給リール台の回転軸に制動をかけた
りするために、適宜な補強シートで裏打ちした帯
状フエルトから成る摺接部材を回転部分のまわり
に押当てることが、従来から行われている。
A sliding contact member made of a band-shaped felt lined with an appropriate reinforcing sheet to prevent the rotating cylinder (rotating drum) of a rotating head scanner of a tape recorder from touching, or to brake the rotating shaft of a tape supply reel stand. Conventionally, it has been done to press the material around the rotating part.
従来の摺接部材は、第５図に示すように、燐青
銅から成る補強シート１の片面に、その両端部を
残して同じ幅のフエルトで成る摺接部２を接着
し、補強シート１の両端部にそれぞれ取付穴３を
形成したのである。 As shown in FIG. 5, the conventional sliding contact member is made by bonding a sliding contact portion 2 made of felt of the same width to one side of a reinforcing sheet 1 made of phosphor bronze, leaving both ends of the reinforcing sheet 1. Attachment holes 3 were formed at both ends.
上記のごとき摺接部材を製造する従来の方法
は、補強シート１と摺動部２を別々に仕上がり寸
法に切断したのち、両者を１本づつ接着し、しか
るのちに両端部に取付穴３をあけることにより、
仕上げるというものであつた。 The conventional method for manufacturing the above-mentioned sliding contact members is to cut the reinforcing sheet 1 and the sliding part 2 separately to the finished dimensions, then glue them together one by one, and then drill the mounting holes 3 at both ends. By opening the
The idea was to finish it.
上述の従来の製造方法によると、補強シート１
は予め仕上がり幅に形成されており、また摺接部
２も所定の仕上がり幅、仕上がり長さに形成され
ているため、接着剤の塗布や重ね合せを行なう工
程に精密さが要求される。また１本づつ製作され

ある問題があつた。
According to the conventional manufacturing method described above, the reinforcing sheet 1
is pre-formed to a finished width, and the sliding contact portion 2 is also formed to a predetermined finished width and finished length, so precision is required in the adhesive application and overlapping processes. In addition, since each tube was manufactured one by one, there was a problem that there was a limit to the improvement in production efficiency.
更に、接着剤の塗布不良があると、補強シート
１と摺接部２との接合面から接着剤が滲出するこ
とがあり、滲出した接着剤が摺接部２を形成する
フエルトを部分的に硬化せしめ、摺接特性に悪影
響を及ぼす問題もあつた。 Furthermore, if the adhesive is poorly applied, the adhesive may ooze out from the joint surface between the reinforcing sheet 1 and the sliding contact part 2, and the oozing adhesive may partially damage the felt that forms the sliding contact part 2. There were also problems with hardening and adversely affecting sliding contact properties.
そこで、この発明は、これらの問題点を解決し
た摺接部材の製造を提供することを目的とする。 Therefore, an object of the present invention is to provide a method for manufacturing a sliding contact member that solves these problems.
上記の問題点を解決するために、この発明は、
プラスチツクシート又は金属シートでなる補強シ

In order to solve the above problems, this invention
A reinforcing sheet material made of a plastic sheet or a metal sheet and a sliding contact material made of felt are bonded together to form a composite material having a width more than twice the finished width, and then mounting holes are drilled, By cutting the strip to a predetermined width and length so as to include the mounting holes at both end portions in the length direction, a strip-shaped sliding contact member having mounting holes at both end portions in the length direction is obtained.
