ゴム帯１を製造するための装置３としては、図２に示すように、酸液を貯えた凝固槽４と、洗浄液中に略横向きの腕部６aを有する案内具６を配した洗浄槽５とを備えたものを示してある。 Preferred embodiments of the present invention will be described below with reference to the drawings.
FIG. 1 is a schematic sectional view showing an example of a rubber band produced by the method for producing a rubber band of the present invention, FIG. 2 is a schematic side view showing an example of a rubber band production apparatus of the present invention, and FIGS. It is the figure which showed the guide tool which is a component of the rubber belt manufacturing apparatus shown in FIG.
As shown in FIG. 1, the rubber band 1 is formed by adhering an appropriate number of round rubber yarns 2 in parallel so that the side surfaces are in contact with each other in one direction.
As shown in FIG. 2, the apparatus 3 for manufacturing the rubber band 1 includes a coagulation tank 4 in which an acid solution is stored and a cleaning tank 5 in which a guide 6 having a substantially lateral arm 6a is disposed in the cleaning liquid. The one with is shown.

凝固槽４は、酢酸などの酸液を貯めた槽であり、ノズル７から押出されたラテックス配合物を凝固させ、適宜数の丸ゴム糸２を連続形成するものである。
丸ゴム糸２の材料としては、用途に適合させ、天然ゴム（NR）、スチレンブタジエンゴム（SBR）、クロロプレンゴム（CR）等適宜材料を使用でき、これらをラテックスに配合し、ラテックス配合物とすることができる。 The coagulation tank 4 is a tank storing an acid solution such as acetic acid, and coagulates the latex compound extruded from the nozzle 7 to continuously form an appropriate number of round rubber yarns 2.
As the material of the round rubber thread 2, it is possible to use natural rubber (NR), styrene butadiene rubber (SBR), chloroprene rubber (CR), etc. as appropriate according to the application. can do.

洗浄槽５は、水などの洗浄液を貯めた槽であり、洗浄液中に案内具６を丸ゴム糸２の送り方向に適宜間隔で配したものである。腕部６aは、送り方向に対して直交状となるように配してある。
案内具６は、横向きの腕部を有する形状としてあり、複数の丸ゴム糸を、送り方向に引張した状態で腕部に接触して通すことにより、隣接する丸糸ゴムの側面を当接させて接着するものである。
本実施形態では、案内具６は、図３、４に示すように、棒材を折曲形成したものとすることができ、垂直方向の支持部６ｂの先端部を横方向に折曲し、上方膨出の湾曲状に折曲して腕部６aを形成し、腕部６ａは、複数の丸ゴム糸が送り方向に引張された状態で下側に接触して横一列状に並列し互いに圧接し合うように形成してある。なお、腕部６aは、下向き傾斜の直線状や下方膨出の湾曲状などに形成することもでき、また、腕部６aを別体として形成してもよい。
案内具６は、洗浄槽５に２箇所設けてあるが、これに限定するものではなく、少なくとも一の案内具６が設けてあればよい。
また、本実施形態では洗浄液中に案内具６を設けてあるが、これに限定するものではなく、ゴム糸２が送入してくる箇所や送出していく箇所など洗浄液外に設けてもよい。 The cleaning tank 5 is a tank in which a cleaning liquid such as water is stored, and guides 6 are arranged in the cleaning liquid at appropriate intervals in the feed direction of the round rubber thread 2. The arm 6a is arranged so as to be orthogonal to the feed direction.
The guide tool 6 has a shape having a lateral arm part, and a plurality of round rubber threads are passed through the arm part while being pulled in the feeding direction, thereby bringing the side surfaces of the adjacent round rubber threads into contact with each other. To be bonded.
In this embodiment, as shown in FIGS. 3 and 4, the guide 6 can be formed by bending a bar, and the front end portion of the vertical support portion 6 b is bent in the lateral direction. The arm 6a is formed by bending upwardly into a curved shape, and the arms 6a are in contact with each other in a state where a plurality of round rubber yarns are pulled in the feeding direction, and are arranged in parallel in a horizontal row. It is formed so as to be in pressure contact with each other. In addition, the arm part 6a can also be formed in the downward inclined linear shape, the downward bulging curved shape, etc., and the arm part 6a may be formed separately.
Although the guide tool 6 is provided in two places in the washing tank 5, it is not limited to this, The at least 1 guide tool 6 should just be provided.
In this embodiment, the guide 6 is provided in the cleaning liquid. However, the present invention is not limited to this. The guide 6 may be provided outside the cleaning liquid, such as a place where the rubber thread 2 is fed in or a place where the rubber thread 2 is sent out. .

凝固槽４で形成した複数の丸ゴム糸２を、直ちに洗浄槽５に送り出し、図３、４に示すように、複数の丸ゴム糸２が腕部６a下側に並列するように配する。丸ゴム糸２には、送り方向に張力が働いているので、腕部６a下側と摺れる状態となり、丸ゴム糸２が腕部６aの頂点側に集束して隣接する丸ゴム糸２の側面同士が当接する。この際、丸ゴム糸２は、酸により凝固しているものの、表面は粘着性があるので、各丸ゴム糸２同士が接着してゴム帯１を形成できる。
この後、乾燥、加硫などを施し、製品とすることができる。 The plurality of round rubber threads 2 formed in the coagulation tank 4 are immediately sent out to the washing tank 5 and arranged so that the plurality of round rubber threads 2 are juxtaposed below the arm portion 6a as shown in FIGS. Since the tension is acting on the round rubber thread 2 in the feeding direction, the round rubber thread 2 is slid to the lower side of the arm portion 6a, so that the round rubber thread 2 converges on the apex side of the arm portion 6a and the adjacent round rubber thread 2 The side surfaces abut. At this time, although the round rubber thread 2 is solidified by acid, the surface is sticky, so that the round rubber threads 2 can be bonded together to form the rubber band 1.
Then, drying, vulcanization, etc. can be given and it can be set as a product.

図５に示すように、洗浄槽５を連続して設けてもよい。この場合、各洗浄槽５１、５２、５３、５４には、並列して案内具６が配してあり、下流工程の洗浄槽の案内具６ほど腕部６aの突き出し長さが長くなるように形成してある。これにより、ゴム帯同士を接着して幅広のゴム帯を形成できる。
例えば、凝固槽４で形成した丸ゴム糸２を、第一の洗浄槽５１で接着して適宜幅のゴム帯１１を形成する。さらに、第二の洗浄槽５２でゴム帯１１同士を接着してゴム帯１２とし、第三の洗浄槽５３でゴム帯１２同士を接着してゴム帯１３とし、第四の洗浄槽５４でゴム帯１３同士を接着して幅広のゴム帯１４を形成する。 As shown in FIG. 5, you may provide the washing tank 5 continuously. In this case, the guides 6 are arranged in parallel in each of the cleaning tanks 51, 52, 53, 54, and the protruding length of the arm portion 6 a becomes longer as the guide tool 6 of the cleaning tank in the downstream process. It is formed. Thereby, rubber bands can be bonded together to form a wide rubber band.
For example, the round rubber thread 2 formed in the coagulation tank 4 is bonded in the first cleaning tank 51 to form a rubber band 11 having an appropriate width. Further, the rubber bands 11 are bonded to each other in the second cleaning tank 52 to form a rubber band 12, the rubber bands 12 are bonded to each other in the third cleaning tank 53 to form the rubber band 13, and the rubber in the fourth cleaning tank 54. A wide rubber band 14 is formed by bonding the bands 13 together.

凝固槽４で太い丸ゴム糸２、例えば直径０．１ｍｍ〜２ｃｍを形成し、上記によりゴム帯を形成した後、ゴム帯を乾燥させる前に、所定間隔で上下に配したローラー間にゴム帯を挿入して押圧し、所定の厚みのゴム帯とすることもできる。   After forming a thick round rubber thread 2, for example, a diameter of 0.1 mm to 2 cm in the coagulation tank 4 and forming the rubber band according to the above, before drying the rubber band, the rubber band is placed between rollers arranged vertically at predetermined intervals. Can be inserted and pressed to form a rubber band having a predetermined thickness.

この製造方法により製造されたゴム帯は、丸糸ゴムの周面に粘着性があるうちに当接させて接着するので、強固に接着でき、使用中にほぐれることがないものであり、紙おむつ、衣料品など幅広い用途で使用できる。   The rubber band manufactured by this manufacturing method is bonded to the peripheral surface of the round thread rubber while it is sticky, so it can be firmly bonded and is not loosened during use. Can be used in a wide range of applications such as clothing.
