もの等が一般に使用されてきた。Conventionally, carrier tape reels 3 have generally been made from processed paper such as Z-ticle board, injection molded from thermoplastic resin such as acrylic, or processed from metal such as aluminum.

られなかった。Although paper reels have the advantage of being relatively inexpensive, paper dust easily falls off the reel 3 due to friction between the reel 3 and the carrier tape 1, and such paper dust easily falls off the carrier tape 1 due to static electricity. The problem of unavoidable problems is that these substances are often adsorbed by substances and mixed into products.

を目的としたものである。Furthermore, paper reels are sensitive to changes in humidity and have problems in terms of shape retention such as peeling. Plastic reels obtained by injection molding do not themselves generate dust, but
If the antistatic coating is not sufficiently applied, static electricity may be generated and dust in the air may be attracted. Furthermore, injection molding is not an economical method because the mold production costs are high. Metal reels have a beautiful appearance, do not generate static electricity, and have excellent strength, but the material cost is extremely high. Because of its heavy weight, it could not meet the demands of the times for weight reduction.0 [Object of the Invention] The present invention was made in view of the above-mentioned problems of the conventional products. The object of the present invention is to provide a method for manufacturing a carrier tape reel that is highly productive and economical.

? A reamer or a copolymer with vinyl chloride containing 3 to 10% by weight of vinyl acetate and having an average degree of polymerization (P) of 650 to 850 is suitable, and a mixture of the two may also be used. If the average degree of polymerization CP') is less than 650, it is unsuitable in terms of impact strength and rigidity! ! If the diameter is larger than 7.850, it will be difficult to process the sheeting, making it suitable for cinema.

適でらる。The copolymers whose main components are butadiene and styrene used in the present invention are butadiene-styrene-methyl methacrylate terpolymer (MBS), acrylonitrile-butadiene, styrene terpolymer (ABS), butadiene-styrene terpolymer (ABS),
Styrene copolymers (BS) are preferred. If the copolymer containing butadiene and styrene is less than 5 parts by weight, the gelation of the resin will be slow and sheeting processing will be difficult. It is unsuitable because it causes a decrease in elongation during heat molding. Moreover, if the weight is larger than 400, the rigidity of the reel molded product will be poor and it will not be suitable for cinema.

00 fd/100 f or more, more preferably a specific surface area of 95 or 11/f or more, and a DBP oil absorption of 350 tae/f.
Highly conductive carbon of 1002 or higher is the best.

ある。If the amount of highly conductive carbon is less than 3% by weight, it will be unsuitable in terms of surface electrical resistance, and if it is more than 15% by weight, carbon will scatter during mixing, mechanical load will increase during cross-rolling, etc. Not only does it become difficult to process, but it is also unsuitable because it causes a decrease in impact strength and elongation during heat molding as a secondary process.
本発明で使用されるプラスチックシートの成形前の厚み
は０．６ｍから１．５−が適当である。The appropriate thickness of the plastic sheet used in the present invention before molding is from 0.6 m to 1.5 m.
厚みが０．６ ｗよシ薄いと、リールのガイド板４及び
７の硬さが不足し保形性が悪くなる。If the thickness is as thin as 0.6 w, the hardness of the guide plates 4 and 7 of the reel will be insufficient, resulting in poor shape retention.
厚みが１．５Ｗよシ厚くなると硬さは改善されるが材料
費が高価になる。又厚みが１．０ｗ以上になるとカレン
ダー等でのシーテイングが極めて困難になるので別工程
で薄手のシートを２枚以上貼シあわせてシートを形成す

さと経済性の兼合いから′厚みは０．６ ｍから１．０
ｍの間が望ましい。If the thickness is increased by 1.5W, the hardness will be improved, but the material cost will be higher. Furthermore, if the thickness exceeds 1.0 W, sheeting using a calendar or the like becomes extremely difficult, so it is necessary to form a sheet by laminating two or more thin sheets together in a separate process. Therefore, the thickness of the reel guide plates 4 and 7 is between 0.6 m and 1.0 m in view of the hardness and economy.
A range between m is desirable.
しかし、この範囲の厚みでは硬さに問題が残りたので鋭
意検討した結果、ソールのガイド板４及び７０表面に凹
凸状のリプを配置することによって補強することが可能
となった。However, with the thickness within this range, there remained a problem with hardness, and after careful consideration, it became possible to strengthen the sole by arranging uneven lips on the surfaces of the guide plates 4 and 70 of the sole.

This method is suitable as an industrial manufacturing method for carrier tape reels, since it can overcome the disadvantages of low economic efficiency due to weight and the like.
