Description
本発明は、複数のゴム芯入り紐を編んで又は縒って、且つリング状にしたゴムリングと、それを製造する方法とに関する。 The present invention relates to a rubber ring formed by knitting or twisting a plurality of strings with a rubber core into a ring shape, and a method for manufacturing the same.
ゴム芯と当該ゴム芯を覆う伸縮性カバーとを備える１本のゴム芯入り紐の両端を接合してリング状にしたゴムリングは、主として髪止め用として、従来より広く使用されている。幾つかの用途において(例えば、ヘアバンドとして使用する場合)、このような従来のゴムリングについて、耐久性と収縮力が弱く、且つ細いという点が問題となることから、近年、複数のゴム芯入り紐を編んで又は縒ってリング状にしたゴムリングが提案されている。このようなゴムリングは、従来のゴムリングのこれら問題点を解決すると共に、色違いのゴム芯入り紐を用いることでデザイン面でも優れている。 BACKGROUND ART A rubber ring in which both ends of one rubber core-containing string provided with a rubber core and an elastic cover that covers the rubber core are joined into a ring shape has been widely used mainly for hair protection. In some applications (for example, when used as a hair band), these conventional rubber rings are problematic in that their durability and shrinkage are weak and thin. A rubber ring has been proposed in which an incoming string is knitted or rolled into a ring shape. Such a rubber ring solves these problems of the conventional rubber ring and is excellent in design by using different colored core cords.
例えば、特許文献１の図８には、２本のゴム芯入り紐を用いたゴム芯入り組紐リング(ゴムリング)が示されている。このゴム芯入り組紐リングは、２本のゴム芯入り紐を交互に撚って両端部を接合することで作製されており、その接合部では、両端部が束ねられて、糸にて縛られると共に、その上から接着面を持つ覆い布が巻かれている。
For example, FIG. 8 of
特許文献１の図８のゴム芯入り組紐リングでは、接合部が覆い布で巻かれているが、この覆い布は、特に色違いのゴム芯入り紐が用いられた場合には、デザイン的に浮いてしまう。また、２本のゴム芯入り紐を交互に撚った縒り紐の両端部が束ねられて覆い布で覆われることから、接合部だけ他の領域よりも径太になってしまう。特許文献１の図８のゴム芯入り組紐リングは、この点でもデザイン的に好ましくなく、さらには、例えば、ゴム芯入り組紐リングがヘアバンドとして使用された場合には、このような接合部は(そこだけ強く押圧するので)使用者に違和感を与えてしまう。加えて、特許文献１の図８のゴム芯入り組紐リングには、両端部を束ねて糸で縛って、その上から覆い布を巻き付けるという接合作業が面倒であるという問題もある。
In the braided ring with rubber core shown in FIG. 8 of
特許文献１の図６に示されたゴム芯入り組紐リングは、上記ゴム芯入り組紐リングの問題点を克服するものとして特許文献１に開示されており、１本のゴム芯入り紐の一端とその中程を合わせて輪部を形成し、輪部の外側に残りの部位を複数回巻き付かせた後、そのゴム芯入り紐の両端を接着することで構成されている。
The rubber cored braid ring shown in FIG. 6 of
特許文献１の図６に示されたゴム芯入り組紐リングでは、図８に示されたゴム芯入り組紐リングにおける接合部の盛り上がりや覆い布の問題は解消されている。しかしながら、１本のゴム芯入り組紐リングを用いているので、図６のゴム芯入り組紐リングは、図８に示されたゴム芯入り組紐リングのように(色違いのゴム芯入り紐を用いて)カラフルさを演出することはできない。さらに、特許文献１の図２乃至図５に示されているように、図６に示されたゴム芯入り組紐リングは、ゴム芯入り組紐の中程を押さえて、一端から中程までの間に撚りを加える工程と、加えた撚りを保ちながら、ゴム芯入り組紐の一端にその中程を合わせて輪部を形成する工程と、この輪部の外にある残りの部位を輪部に複数回巻き付かせる工程と、ゴム芯入り紐の両端を接着する工程とを必要としている。１つのゴム芯入り組紐リングを作製する毎に、撚りを加える工程と、輪部を形成する工程と、輪部以外の部位を輪部に複数回巻き付かせる工程とを手作業で行うことは極めて面倒であって、図６に示されたゴム芯入り組紐リングは、製造工程の点で、図８に示されたゴム芯入り組紐リングよりも優れているとは到底言い難い。また、製造されるゴム芯入り組紐リングに個体差が生じやすいという問題もある。

本発明の第１又は第２のゴムリングの製造方法では、前記固化剤は、膨張剤、分解菌、分解酵素、又は有機溶剤系洗浄剤を含んでおり、固化すると多孔質になってよい。 In the first or second method for producing a rubber ring according to the present invention, the solidifying agent contains a swelling agent, a degrading bacterium, a degrading enzyme, or an organic solvent-based cleaning agent, and may become porous when solidified.
本発明のゴムリングでは、複数のゴム芯入り紐を編んで又は縒って構成したゴム組紐が、その両端面を接着することでリング状に構成されているので、接合部にて径太にならず、接合部がゴムリングの美観を損ねることはない。固化剤を用いることによって、ゴム組紐の両端部にて、複数のゴム芯入り紐の複数の伸縮性カバーが一体に固められており、複数のゴム芯入り紐が解けない状態で、ゴム組紐の両端面を接着できるので、本発明のゴムリングにより、ゴム組紐をリング状にする工程は簡単且つ容易になる。 In the rubber ring of the present invention, the rubber braid formed by knitting or twisting a plurality of cords with a rubber core is formed in a ring shape by bonding the both end surfaces, so that the diameter is increased at the joint portion. In other words, the joint does not impair the aesthetics of the rubber ring. By using a solidifying agent, a plurality of elastic covers of a plurality of rubber cored cords are solidified integrally at both ends of the rubber braid, and in a state where the plurality of rubber cored cords cannot be unwound, Since both end faces can be bonded, the rubber ring of the present invention makes the process of forming the rubber braid into a ring shape simple and easy.
本発明のゴムリングでは、ゴム組紐の両端部にて、各ゴム芯入り紐のゴム芯及び伸縮性カバーも一体に固められている。これによって、伸縮性カバーの端部の毛羽立ちが抑制されると共に、ゴム芯の端面が伸縮性カバー内に入って凹まないので、(特許文献１の図８のゴム芯入り組紐リングのように結束用の糸や覆い布を用いることなく)ゴム組紐の両端面を接着剤を用いて簡単に且つ強固に接合できる。さらに、固化剤が固化した固化部分が多孔質にされることで、ゴム組紐の両端面はさらに強固に接着される。 In the rubber ring of the present invention, the rubber core of each rubber core and the stretchable cover are integrally hardened at both ends of the rubber braid. As a result, fuzz at the end of the elastic cover is suppressed, and the end face of the rubber core enters the elastic cover and does not dent, so that it is bound (like the braided ring with rubber core in FIG. 8 of Patent Document 1). The both ends of the rubber braid can be easily and firmly joined using an adhesive (without using a thread or covering cloth). Furthermore, since the solidified part solidified by the solidifying agent is made porous, both end surfaces of the rubber braid are bonded more firmly.
本発明の第１及び第２のゴムリングの製造方法では、ゴム組紐を固化剤で固める工程を行い、その後、固まった部分を分断することで、複数のゴム芯入り紐が両端部にて解けない状態のゴム組紐が得られる。そして、当該ゴム組紐の両端を接着する工程が簡単且つ容易に行われる。製造されたゴムリングは、接合部にて径太にならず、接合部がゴムリングの美観を損ねることはない。さらに、ゴム組紐の両端部にて、各ゴム芯入り紐のゴム芯及び伸縮性カバーが一体に固められているので、伸縮性カバーの端部の毛羽立ちが抑制されると共に、ゴム芯の端面が伸縮性カバー内に入って凹まないので、ゴム組紐の両端面は、接着剤を用いて簡単に且つ強固に接合される。膨張剤、分解菌、又は分解酵素を含んだ固化剤を用いることで、固化剤が固化した固化部分に細孔が形成されて、ゴム組紐の両端はさらに強固に接着剤で接着される。 In the first and second rubber ring manufacturing methods of the present invention, a step of solidifying the rubber braid with a solidifying agent is performed, and then the solidified portion is divided, so that a plurality of cords with rubber cores are unwound at both ends. A rubber braid without any condition is obtained. And the process which adhere | attaches the both ends of the said rubber braid is performed simply and easily. The manufactured rubber ring does not become thick at the joint, and the joint does not impair the aesthetics of the rubber ring. Furthermore, since the rubber core of each rubber core and the elastic cover are integrally hardened at both ends of the rubber braid, fuzz at the end of the elastic cover is suppressed, and the end surface of the rubber core is Since it does not dent into the elastic cover, both end surfaces of the rubber braid are simply and firmly joined using an adhesive. By using a solidifying agent containing an expanding agent, decomposing bacteria, or degrading enzyme, pores are formed in the solidified portion where the solidifying agent is solidified, and both ends of the rubber braid are more firmly bonded with an adhesive.

図４に示すように、ゴム組紐(11)に含浸した固化剤(51)が固化して固化部分(53)が形成されることによって、ゴム組紐(11)の第１端部(19a)では、ゴム芯入り紐(13a)(13b)のゴム芯(15a)(15b)の各々とそれを覆う伸縮性カバー(17a)(17b)とも一体に固められている。同様に、第１端部(19a)では、ゴム芯入り紐(13c)のゴム芯(15c)とそれを覆う伸縮性カバー(17c)も一体に固められている(図示せず)。また、ゴム組紐(11)の第２端部(19b)においても、ゴム芯入り紐(13a)(13b)(13c)のゴム芯(15a)(15b)(15c)の各々とそれを覆う伸縮性カバー(17a)(17b)(17c)とは一体に固められている。 As shown in FIG. 4, the solidifying agent (51) impregnated in the rubber braid (11) is solidified to form a solidified portion (53), whereby the first end (19a) of the rubber braid (11) is formed. Each of the rubber cores (15a) and (15b) of the rubber core-containing strings (13a) and (13b) and the elastic covers (17a) and (17b) covering the rubber cores (15a) and (15b) are integrally hardened. Similarly, at the first end portion (19a), the rubber core (15c) of the string (13c) with the rubber core and the elastic cover (17c) covering the same are firmly fixed (not shown). Also, at the second end (19b) of the rubber braid (11), each of the rubber cores (13a), (13b) and (13c) of the rubber cores (15a), (15b) and (15c) and the expansion and contraction covering them.

図５は、図４に示されているゴム芯入り紐(13b)の断面を拡大したものであって、固化剤(51)が固化した固化部分(53)に多数の細孔(55)が形成されている模様を模式的に示している。本発明では、このように、固化部分(53)に多数の細孔(55)が形成されることが好ましい。ゴム組紐(11)の両端面を接着剤(31)で接着する際に、固化部分(53)の細孔(55)に接着剤(31)が浸透することで、接着面積が増大するからである。 FIG. 5 is an enlarged view of the cross section of the rubber core-containing string (13b) shown in FIG. 4, and a large number of pores (55) are formed in the solidified portion (53) where the solidifying agent (51) is solidified. The pattern currently formed is shown typically. In the present invention, it is preferable that a large number of pores (55) are formed in the solidified portion (53) as described above. When the both ends of the rubber braid (11) are bonded with the adhesive (31), the adhesive (31) penetrates into the pores (55) of the solidified portion (53), thereby increasing the bonding area. is there.
図６(ａ)乃至(ｄ)は、各々がゴム芯とそのゴム芯を覆う繊維糸製伸縮性カバーとを備える複数のゴム芯入り紐を編んで(又は縒って)リング状にしたゴムリングを製造する本発明の第１の製造方法の実施例であって、上記ゴムリング(1)を製造する工程を示している。 6 (a) to 6 (d) show a ring-shaped rubber made by knitting (or twisting) a plurality of strings with a rubber core each having a rubber core and a fiber yarn stretchable cover covering the rubber core. It is an Example of the 1st manufacturing method of this invention which manufactures a ring, Comprising: The process of manufacturing the said rubber ring (1) is shown.
本実施例では、まず、図６(ａ)に示すように、長尺のゴム組紐(11')が準備される。長尺のゴム組紐(11')は、長尺のゴム芯入り紐(13a')(13b')(13c')を編み機等を用いて三つ編みにすることで作製されている。 In the present embodiment, first, as shown in FIG. 6A, a long rubber braid (11 ′) is prepared. The long rubber braid (11 ′) is produced by braiding the long rubber core-containing strings (13a ′), (13b ′), and (13c ′) using a knitting machine or the like.
次に、図６(ｂ)に示すように、長尺のゴム組紐(11')の長さ方向に所定の間隔(或いは所定の周期又は距離)で離れた複数の箇所にて、長尺のゴム組紐(11')に液状の固化剤(51)を含浸させる工程が行われる。当該所定の間隔は、作製されるゴムリング(1)の周長又は展開長さＬを踏まえて設定される。当然のことなから、当該工程において、長尺のゴム組紐(11')が引き伸ばされている場合には、当該所定の間隔は、ゴムリング(1)の周長Ｌよりも長くなる(しかしながら、図６(ｄ)に示す切断工程の後に得られる１又は複数の短尺のゴム組紐(11)の長さは、ゴムリング(1)の周長Ｌと等しくされる)。 Next, as shown in FIG. 6 (b), the long rubber braid (11 ') is elongated at a plurality of locations separated by a predetermined interval (or a predetermined cycle or distance) in the length direction. A step of impregnating the rubber braid (11 ′) with the liquid solidifying agent (51) is performed. The predetermined interval is set based on the circumferential length or the developed length L of the rubber ring (1) to be manufactured. Of course, when the long rubber braid (11 ′) is stretched in the process, the predetermined interval is longer than the circumferential length L of the rubber ring (1) (however, The length of one or more short rubber braids (11) obtained after the cutting step shown in FIG. 6 (d) is made equal to the circumferential length L of the rubber ring (1)).
固化剤(51)としては、固化作用成分を溶媒に溶解させたものが使用される。さらには、上述したように、固化剤(51)が固化した固化部分(53)に細孔(55)を形成するために、膨張剤が固化剤(51)に含められる。例えば、溶媒として水を、固化作用成分としてポリビニールアルコール系糊を、膨張剤として炭酸水素ナトリウムを含んでいる固化剤(51)が使用されてよい。 As the solidifying agent (51), a solidifying component dissolved in a solvent is used. Further, as described above, an expansion agent is included in the solidifying agent (51) in order to form pores (55) in the solidified portion (53) where the solidifying agent (51) has solidified. For example, a solidifying agent (51) containing water as a solvent, polyvinyl alcohol-based glue as a solidifying component, and sodium hydrogen carbonate as an expanding agent may be used.
固化剤(51)の溶媒としては、水以外に、有機溶剤などが使用されてよい。固化作用成分としては、ポリビニールアルコール系糊の他に、小麦粉、でんぷん粉や上新粉などがあるが、これらに限定されない。膨張剤としては、炭酸水素ナトリウムの他に、炭酸水素アンモニウム、塩化アンモニウム、炭酸アンモニウム、酒石酸、酒石酸水素カリウム、焼ミョウバン、イーストパウダー、ベーキングパウダーなどがあるが、これらに限定されない。本発明で使用可能な膨張剤には、発泡剤として一般に認識又は使用されているものも含まれる。 As a solvent for the solidifying agent (51), an organic solvent or the like may be used in addition to water. Examples of the solidifying component include, but are not limited to, wheat flour, starch powder, and superfine powder in addition to the polyvinyl alcohol-based paste. Examples of the swelling agent include, but are not limited to, ammonium bicarbonate, ammonium bicarbonate, ammonium chloride, ammonium carbonate, tartaric acid, potassium hydrogen tartrate, baked alum, yeast powder, baking powder, and the like. The swelling agents that can be used in the present invention include those that are generally recognized or used as blowing agents.
本実施例では、上記所定の間隔で配置された複数のノズル(71a)(71b)を介して液状の固化剤(51)をゴム組紐(11')に滴下することで、ゴム組紐(11')に固化剤(51)を塗布又は付着させている。長尺のゴム組紐(11')は、直線状に水平に配置されており、その上に一列に配置された複数のノズル(71a)(71b)が、放出口を下側にして配置される。複数のノズル(71a)(71b)の上流側は、固化剤(51)を貯蔵したタンクと繋がっており、当該タンクと複数のノズル(71a)(71b)と繋ぐ流路には、固化剤(51)の滴下を制御するバルブ等の機構が設けられている(何れも図示せず)。図６(ｂ)では、２本のノズル(71a)(71b)のみが図示されているが、ノズル(71a)(71b)の数、つまり、液状の固化剤(51)を含浸させる箇所(又は、固化剤(51)で固められる箇所)の数が３以上であってよいのは当然のことである。 In this embodiment, the liquid braid (51 ′) is dropped onto the rubber braid (11 ′) via the plurality of nozzles (71a) (71b) arranged at the predetermined intervals, thereby the rubber braid (11 ′ ) Is applied or adhered to the solidifying agent (51). The long rubber braid (11 ′) is arranged in a straight line and horizontally, and a plurality of nozzles (71a) and (71b) arranged in a row thereon are arranged with the discharge port on the lower side. . The upstream side of the plurality of nozzles (71a) (71b) is connected to a tank that stores the solidifying agent (51). A mechanism such as a valve for controlling the dropping of 51) is provided (none is shown). In FIG. 6 (b), only two nozzles (71a) and (71b) are shown, but the number of nozzles (71a) and (71b), that is, a place (or a position where liquid solidifying agent (51) is impregnated (or Of course, the number of the solidifying agent (51) can be 3 or more.
複数のノズル(71a)(71b)から固化剤(51)を滴下する手法以外の手法を用いて、ゴム組紐(11')に固化剤(51)が塗布又は付着されてもよい。例えば、固化剤(51)は、複数のノズル(71a)(71b)からゴム組紐(11')に向かって噴出されてよい。また、ゴム組紐(11')に沿って１本のノズルを水平移動させることで、所定の間隔で固化剤(51)がゴム組紐(11')に塗布又は付着されてもよい。さらには、固化剤(51)が付着又は含浸した部材(例えば、ハケやスポンジ)をゴム組紐(11')に当てることで、所定の間隔で固化剤(51)がゴム組紐(11')に塗布又は付着されてもよい。 The solidifying agent (51) may be applied or adhered to the rubber braid (11 ′) using a technique other than the technique of dropping the solidifying agent (51) from the plurality of nozzles (71a) (71b). For example, the solidifying agent (51) may be ejected from the plurality of nozzles (71a) (71b) toward the rubber braid (11 ′). Further, the solidifying agent (51) may be applied or adhered to the rubber braid (11 ') at a predetermined interval by horizontally moving one nozzle along the rubber braid (11'). Further, the solidifying agent (51) is applied to the rubber braid (11 ′) at a predetermined interval by applying a member (for example, a brush or sponge) adhered or impregnated with the solidifying agent (51) to the rubber braid (11 ′). It may be applied or attached.
図６(ｂ)に示すように長尺のゴム組紐(11')に液状の固化剤(51)を含浸させる工程が行われると、ゴム組紐(11')に含浸した固化剤(51)を乾燥させて固化させる工程が行われる。この工程は、自然乾燥によって行われてもよいが、例えば、長尺のゴム組紐(11')に温風を当てることで、固化剤(51)の乾燥が促進されてもよい。固化剤(51)の乾燥中に、固化剤(51)中の水分や揮発性成分は、蒸発又は気化して、乾燥した固化部分(53)には、それら蒸発や気化によって多数の微細孔が残り、多孔質となる。膨張剤は、それら微細孔を拡大させて細孔(55)を形成する働きをする。例えば、固化剤(51)が膨張剤として炭酸水素ナトリウムを含んでいる場合には、炭酸水素ナトリウムは６５℃以上で分解するので、ゴム組紐(11')の温度はそれを超える温度(例えば、７０℃程度)にされるのが好ましい。 When the step of impregnating the long rubber braid (11 ′) with the liquid solidifying agent (51) is performed as shown in FIG. 6B, the solidifying agent (51) impregnated in the rubber braid (11 ′) is removed. A step of drying and solidifying is performed. This step may be performed by natural drying. For example, drying of the solidifying agent (51) may be promoted by applying warm air to the long rubber braid (11 ′). During the drying of the solidifying agent (51), moisture and volatile components in the solidifying agent (51) are evaporated or vaporized, and the dried solidified portion (53) has a large number of fine pores due to the evaporation and vaporization. The remainder becomes porous. The swelling agent functions to enlarge the micropores to form pores (55). For example, when the solidifying agent (51) contains sodium bicarbonate as an expanding agent, sodium bicarbonate decomposes at 65 ° C. or higher, so that the temperature of the rubber braid (11 ′) exceeds that (for example, About 70 ° C.).
固化剤(51)が乾燥して固化部分(53)が形成されると、図６(ｃ)に示すように、固化剤(51)が含浸したゴム組紐(11')の部分(21a)(21b)が固められる。当該部分(21a)(21b)では、先に説明したように、長尺のゴム芯入り紐(13a')(13b')(13c')の各々のゴム芯及び伸縮性カバーが一体に固められており、さらに、ゴム芯入り紐(13a')(13b')(13c')が離れないように、それらの伸縮性カバーも一体に固められている。 When the solidifying agent (51) is dried to form a solidified portion (53), as shown in FIG. 6 (c), the rubber braid (11 ′) portion (21a) (21a) impregnated with the solidifying agent (51) ( 21b) is hardened. In the portions (21a) and (21b), as described above, the rubber cores and the elastic covers of the long rubber core-containing strings (13a ′), (13b ′), and (13c ′) are solidified integrally. Furthermore, the elastic covers are also solidified so that the strings (13a '), (13b'), and (13c ') with rubber cores are not separated.
次に、図６(ｄ)に示すように、固化剤(51)で固められた複数の部分(21a)(21b)の各々が分断されるように長尺のゴム組紐(11')を上記の所定の間隔で(長さ方向と直交して)切断する工程が行われる。このように長尺のゴム組紐(11')が切断されることで、両端部(19a)(19b)が固まっている１又は複数の短尺のゴム組紐(11)が得られる。固化剤(51)で予め固められた(21a)(21b)が分断されることで、第１端部(19a)及び第２端部(19b)にて、切断に起因したゴム芯入り紐(13a)(13b)(13c)の毛羽立ちが抑制されると共に、ゴム芯(15a)(15b)(15c)が収縮して、それらの端面が伸縮性カバー(17a)(17b)(17c)内に入り込む事態が防止される。その結果、ゴム組紐(11)の第１端部(19a)及び第２端部(19b)の端面は、突き合わせて接着し易いように(巨視的に)平坦にされる。 Next, as shown in FIG. 6 (d), the long rubber braid (11 ′) is attached so that each of the plurality of portions (21a) and (21b) solidified by the solidifying agent (51) is divided. A step of cutting at a predetermined interval (perpendicular to the length direction) is performed. By cutting the long rubber braid (11 ′) in this way, one or a plurality of short rubber braids (11) having both ends (19a) (19b) solidified are obtained. (21a) (21b) preliminarily solidified with the solidifying agent (51) is divided, so that the first end (19a) and the second end (19b) have rubber core-cored strings ( 13a) (13b) (13c) fuzz is suppressed, the rubber core (15a) (15b) (15c) shrinks, the end surfaces of them in the elastic cover (17a) (17b) (17c) Intrusion is prevented. As a result, the end surfaces of the first end portion (19a) and the second end portion (19b) of the rubber braid (11) are flattened (macroscopically) so that they can be abutted and bonded easily.
図６(ｄ)に示す切断工程の後、切断工程で得られた各ゴム組紐(11)の両端面が接着剤(31)を用いて接着されることで、図１に示すようなゴムリング(1)が作製される。接着工程では、例えば、一方の端面に接着剤(31)を塗布した後に、両端面どうしを突き合わせて、突き合わせ方向に加圧することで、ゴム組紐(11)の両端面が接合される。接着剤(31)としては、浸透性を有しており、且つ非水溶性の接着剤が使用されるのが好ましく、例えば、シアノアクリレート系接着剤が使用されてよい。 After the cutting step shown in FIG. 6 (d), the rubber braids (11) obtained in the cutting step are bonded to each other using an adhesive (31), so that a rubber ring as shown in FIG. (1) is produced. In the bonding step, for example, after the adhesive (31) is applied to one end surface, both end surfaces are butted together and pressed in the butting direction, whereby both end surfaces of the rubber braid (11) are joined. As the adhesive (31), a penetrable and water-insoluble adhesive is preferably used. For example, a cyanoacrylate adhesive may be used.
ゴム組紐(11)の両端面の接合は、図１に示すように、ゴム組紐(11)を構成するゴム芯入り紐(13a)(13b)(13c)の各々の端面どうしを突き合わせて接着することが、デザイン的には好ましいが、必ずしもそのように接合する必要はない。例えば、異なるゴム芯入り紐(13a)(13b)(13c)の端面を突き合わせて接着してもよい。 As shown in FIG. 1, both ends of the rubber braid (11) are bonded to each other by bringing the end faces of the rubber core-containing cords (13a), (13b) and (13c) constituting the rubber braid (11) into contact with each other. This is preferable in terms of design, but it is not always necessary to perform such joining. For example, the end surfaces of different rubber-cored cords (13a), (13b), and (13c) may be abutted and bonded.
図７(ａ)乃至(ｃ)と図８(ａ)及び(ｂ)は、各々がゴム芯と前記ゴム芯を覆う繊維糸製伸縮性カバーとを備える複数のゴム芯入り紐を編んで(又は縒って)リング状にしたゴムリングを製造する本発明の第２の製造方法の第１実施例であって、上記ゴムリング(1)を製造する工程を示している。 7 (a) to 7 (c) and FIGS. 8 (a) and 8 (b) are knitted with a plurality of rubber core cords each having a rubber core and a fiber yarn stretchable cover covering the rubber core ( Or, it is a first embodiment of the second manufacturing method of the present invention for manufacturing a ring-shaped rubber ring, and shows a process for manufacturing the rubber ring (1).
本実施例では、まず、先の実施例と同じく、図６(ａ)に示すような長尺のゴム組紐(11')が準備される。次に、図７(ａ)に示すように、長尺のゴム組紐(11')の長さ方向に所定の間隔(或いは、所定の周期又は距離)で離れた複数箇所において、長尺のゴム芯入り紐(13a')(13b')(13c')を、破断可能な結束部材(91)を用いて結束する工程が実行される。本実施例では、結束部材(91)である帯体が所定の間隔でゴム組紐(11')に巻き付けられている。帯体としては、例えば、市販の粘着テープが使用されてよい。結束部材で結束される箇所の間隔は、作製されるゴムリング(1)の周長又は展開長さＬと結束部材(91)の幅を考慮して決定される。なお、先の実施例と同様に、長尺のゴム組紐(11')が引き伸ばされている場合には、当該所定の間隔は、その伸びを考慮して設定される。図７(ａ)には、２つの結束部材(91)のみが図示されているが、結束部材(91)の数、つまり、長尺のゴム組紐(11')のゴム芯入り紐(13a')(13b')(13c')を結束する箇所の数は、３以上であってよいのは当然のことである。 In this embodiment, first, as in the previous embodiment, a long rubber braid (11 ′) as shown in FIG. 6A is prepared. Next, as shown in FIG. 7 (a), the long rubber braid (11 ') is elongated at a predetermined interval (or at a predetermined cycle or distance) at a plurality of locations. A step of binding the cored strings (13a ′), (13b ′), and (13c ′) by using a breakable binding member (91) is performed. In the present embodiment, the band as the binding member (91) is wound around the rubber braid (11 ′) at a predetermined interval. As the band, for example, a commercially available adhesive tape may be used. The interval between the portions to be bound by the binding member is determined in consideration of the circumferential length or the developed length L of the produced rubber ring (1) and the width of the binding member (91). As in the previous embodiment, when the long rubber braid (11 ′) is stretched, the predetermined interval is set in consideration of the stretch. FIG. 7 (a) shows only two binding members (91). However, the number of the binding members (91), that is, the long rubber braid (11 ′) of the rubber core-cored cord (13a ′) is shown. Of course, the number of locations where () (13b ′) (13c ′) are bound may be three or more.
次に、図７(ｂ)に示すように、結束部材(91)の各々が分断されるように長尺のゴム組紐(11')を上記の所定の間隔で切断する工程が行われる。このように長尺のゴム組紐(11')が切断されることで、分断された結束部材(93a)(93b)で両端が結束された１又は複数の短尺のゴム組紐(11'')が得られる。本実施例では、各結束部材(91)は、幅が等しい２つの結束部材(93a)(93b)に分断される。短尺のゴム組紐(11'')の長さＬ'は、ゴムリング(1)の周長又は展開長さＬに結束部材(91)を加えた値よりも長くされる。 Next, as shown in FIG. 7 (b), a step of cutting the long rubber braid (11 ′) at the predetermined interval is performed so that each of the binding members (91) is divided. By cutting the long rubber braid (11 ′) in this way, one or a plurality of short rubber braids (11 ″) bound at both ends by the split bundling members (93a) and (93b) are obtained. can get. In this embodiment, each binding member (91) is divided into two binding members (93a) and (93b) having the same width. The length L ′ of the short rubber braid (11 ″) is made longer than the value obtained by adding the bundling member (91) to the circumferential length or developed length L of the rubber ring (1).
次に、切断工程で得られた１又は複数の短尺のゴム組紐(11'')の各々について、各結束部材(93a)(93b)に隣接又は近接した部分に液状の固化剤(51)を含浸させる工程が行われる。固化剤(51)を含浸させる部分は、これら結束部材(93a)(93b)の間に位置している。言い換えると、含浸工程では、少なくとも、各結束箇所からゴム組紐(11'')の長さ方法に沿って内側にある部分、つまり結束部材(93a)(93b)の各々からゴム組紐(11'')の長さ方向について内側にある部分にて、液状の固化剤(51)をゴム組紐(11'')に含浸させる。本実施例では、本工程は、図７(ｃ)に示すように、容器又は漕に入れられた固化剤(51)に、(分断された)結束部材(93a)(93b)が固化剤(51)の液面下に位置するようにゴム組紐(11'')の両端部の各々を浸漬することで実行される。 Next, for each of one or a plurality of short rubber braids (11 '') obtained in the cutting step, a liquid solidifying agent (51) is applied to a portion adjacent to or adjacent to each binding member (93a) (93b). An impregnation step is performed. The portion impregnated with the solidifying agent (51) is located between the binding members (93a) and (93b). In other words, in the impregnation step, the rubber braid (11 '' from each of the binding members (93a) and (93b), that is, at least the part located inside along the length method of the rubber braid (11 '') from each binding location. The rubber braid (11 ″) is impregnated with a liquid solidifying agent (51) at a portion on the inner side in the length direction. In this example, as shown in FIG. 7 (c), in this step, the (divided) binding members (93a) and (93b) are added to the solidifying agent (51) in the solidifying agent (51) placed in a container or a basket. 51) It is carried out by immersing each end of the rubber braid (11 ″) so as to be located below the liquid level.
含浸工程は、例えば、分断された結束部材(93a)(93b)で結束された箇所から(ゴム組紐(11'')の長さ方向について)内側にある部分に、ゴム組紐(11'')に液状の固化剤(51)を塗布又は付着させることで実行されてもよい。図７(ｃ)に例示した工程では、結束部材(93a)(93b)で結束された部分にも、ゴム組紐(11'')に固化剤(51)が含浸するが、固化剤(51)が含浸、塗布又は付着される部分又は箇所は、結束部材(93a)(93b)から若干離れていてもよい。固化剤(51)については、先の実施例と同様である。 In the impregnation step, for example, the rubber braid (11 '') from the portion bound by the divided binding members (93a) and (93b) to the inner part (in the length direction of the rubber braid (11 '')) It may be carried out by applying or adhering a liquid solidifying agent (51) to the surface. In the process illustrated in FIG. 7C, the rubber braid (11 ″) is impregnated with the solidifying agent (51) even in the portion bound by the binding members (93a) and (93b). The portion or the place where the material is impregnated, applied or adhered may be slightly separated from the binding members (93a) and (93b). The solidifying agent (51) is the same as in the previous example.
含浸工程の後、各ゴム組紐(11'')に含浸した固化剤(51)を乾燥させて固化させる工程が行われる。この工程は、先の実施例と同様に、自然乾燥によって行われてもよいが、例えば、ゴム組紐(11'')に温風を当てることで、固化剤(51)の乾燥が促進されてもよい。 After the impregnation step, a step of drying and solidifying the solidifying agent (51) impregnated in each rubber braid (11 ″) is performed. This step may be performed by natural drying as in the previous embodiment.For example, by applying warm air to the rubber braid (11 ''), drying of the solidifying agent (51) is promoted. Also good.
固化剤(51)が乾燥すると、図８(ａ)に示すように、各結束部材(93a)(93b)に隣接又は近接した含浸部分(23a)(23b)にて、ゴム組紐(11')が固められる。言い換えると、少なくとも、各結束箇所からから(ゴム組紐(11'')の長さ方向について)内側にある部分(23a)(23b)、つまり少なくとも結束部材(93a)(93b)から内側の部分(23a)(23b)にて、ゴム組紐(11')が固化剤(51)で固められる。当該部分(23a)(23b)では、先に説明したように、ゴム組紐(11'')を構成するゴム芯入り紐(13a'')(13b'')(13c'')の各々のゴム芯及び伸縮性カバーが一体に固められており、さらに、ゴム芯入り紐(13a'')(13b'')(13c'')が離れないように、それらの伸縮性カバーも一体に固められている。 When the solidifying agent (51) is dried, as shown in FIG. 8 (a), the rubber braid (11 ′) at the impregnated portions (23a) and (23b) adjacent to or close to the binding members (93a) and (93b). Is hardened. In other words, at least from each binding location (in the length direction of the rubber braid (11 '')) the inner part (23a) (23b), that is, at least the inner part from the binding members (93a) (93b) ( In 23a) and 23b, the rubber braid (11 ') is hardened with the solidifying agent (51). In the parts (23a) and (23b), as described above, each rubber of the rubber cored cords (13a '') (13b '') (13c '') constituting the rubber braid (11 '') The core and elastic cover are solidified together, and the elastic cover is also solidified so that the string with rubber core (13a '') (13b '') (13c '') is not separated ing.
次に、図８(ｂ)に示すように、固められた部分(23a)(23b)が分断されるようにゴム組紐(11'')の両端部を(長さ方向と直交して)切断して除去する工程が行われる。当該工程は、切断後の長さがゴムリング(1)の周長Ｌと同じになるように実行され、その結果、両端部(19a)(19b)が固まっているゴム組紐(11)が得られる。その後、先の実施例と同様な接着工程によってゴム組紐(11)がリング状にされることで、図１に示したゴムリング(1)が完成する。 Next, as shown in FIG. 8 (b), both ends of the rubber braid (11 ″) are cut (perpendicular to the length direction) so that the hardened portions (23a) and (23b) are divided. Then, the removing step is performed. This process is executed so that the length after cutting is the same as the circumferential length L of the rubber ring (1), and as a result, the rubber braid (11) in which both ends (19a) (19b) are solid is obtained. It is done. Thereafter, the rubber braid (11) is formed into a ring shape by the same bonding process as in the previous embodiment, whereby the rubber ring (1) shown in FIG. 1 is completed.
