Description

  The present invention relates to a method for producing a braided ring with a rubber core.

Conventionally, a braided ring with a rubber core is known in which a braided string with a rubber core covered with a braided string is formed in a ring shape. Such a braided braided ring is widely used, for example, for binding hair.
Japanese Patent Laid-Open No. 2002-240154

  By the way, as a method of manufacturing the braided ring with rubber core as described above, for example, there is a method of forming a ring body by cutting the braided braid with a predetermined length and connecting both ends thereof with connecting members. It is used. However, the ring body formed by this method has a problem that the connecting member tends to have an adverse effect during use, and the connecting member impairs the appearance. In addition, a method of forming a ring body by simply joining the cut surfaces of both ends with an adhesive without using a connecting member is also conceivable, but in this method, the braid is likely to fray or fluff near the cut portion. There was a problem.

  In order to solve such a problem, a technique such as Patent Document 1 is provided. In this technique, a cooling solidifying agent is applied to the braided braid before cutting at predetermined intervals, and then the portion where the cooling solidifying agent is applied is cut, and both ends of the cut body are joined with an adhesive. This forms a ring body. However, in this method, since it is necessary to impregnate the cooling solidifying agent over a predetermined region in the vicinity of the joint so as not to cause fraying, the stretchability is suppressed in the impregnated region and the bending becomes difficult.

  The present invention has been made on the basis of the above circumstances, and is a braided ring with a rubber core that is less likely to fray or fluff near the joint and is less likely to lose stretchability or bendability near the joint.

  As shown in the perspective view of FIG. 13, the braided ring 1 with a rubber core obtained by the manufacturing method of the present embodiment is bonded to both ends of a braided rubber string 2 cut to a predetermined length to form a ring shape. Is formed. As shown in the cross-sectional view of FIG. 14, the rubber core-containing braid 2 that is a material of the rubber core-containing braid ring 1 includes a rubber core 3 constituted by a rubber member and a braid 4 that covers the rubber core 3. ing. The rubber core 3 and the braid 4 thereof have elasticity, and as a result, the entire rubber core-containing braid ring 1 according to this embodiment is also rich in elasticity.

The manufacturing method of the braided ring with rubber core according to the present invention is roughly described as follows.
First, a covering portion forming step of forming a covering portion 12 by winding a sticking member around the rubber braided braid 2 as shown in FIG. 1 at predetermined intervals as shown in FIG. 2, and then as shown in FIG. Then, a cutting step of cutting the intermediate portion of each covering portion 12 in the braided cord 2 with rubber core to form the cut body 20 is performed. In addition, although the position to cut | disconnect should just be the intermediate part (part between both ends) of each coating | coated part 12, it is desirable to cut | disconnect the center vicinity. Further, as shown in FIG. 7 and FIG. 8, the bonding step of forming the ring body by bonding the cut surfaces 20a at both ends of the cut body 20 formed in the cutting step via the first adhesive. After that, an affixing member removing step for removing the affixing member is performed, and finally a braided ring 1 with a rubber core as shown in FIG. 13 is formed. Hereinafter, each process etc. are demonstrated concretely.

(Coating part forming step)
In the covering portion forming step, an adhesive tape 10 (adhesive tape 10 corresponds to a sticking member) longer than the outer periphery of the rubber cored braid 2 is applied to the rubber cored braid 2 of FIG. 1 as shown in FIG. The covering portion 12 is formed by winding the braided cord 2 with a rubber core. At that time, as shown in FIG. 3, both end portions 10d, 10d of the adhesive tape 10 are extended to the side of the braided cord 2 with rubber core, and both end portions 10d, 10d of the extending adhesive tape 10 are connected to each other. The bonded portion 11 is formed by bonding.

(Pressing process)
Prior to the cutting step described later, a pressing step is performed. In this pressing step, as shown in FIG. 4, both end portions 10 d and 10 d of the adhesive tape 10 are in contact with each other with respect to the base end portion of the bonding portion 11 extending laterally from the braided cord 2 with rubber core. Press to. That is, immediately after the covering portion forming step, the base end portion of the bonding portion 11 is as shown in FIG. 3, and the roller 60 is applied to the region including the base end portion of the bonding portion 11 as shown in FIG. 3, the non-joined portions of the base end portions are pressed against each other as shown by 11 ′ in FIG. 3, and the bonded portion 11 is formed to a position closer to the rubber core-containing braid 2. Such a pressing step may be omitted.

(Cutting process)
In the cutting step, as shown in FIG. 5, for the braid 2 with a rubber core formed with the covering portion 12 and the bonding portion 11, the intermediate portion of the covering portion 12 and the intermediate portion of the bonding portion 11 are respectively cut. As shown in FIG. 6, the cut body 20 in which the covering portion 12 and the bonding portion 11 are provided at both ends thereof is formed. The cutting can be performed by an instrument or a machine having a cutting tool (such as scissors or a cutting tool such as a cutter knife).

(Adhesion process)
The adhesion process is configured by an application process and a bonding process. In the application step, the first adhesive 22 is applied to the central region spaced from the outer periphery on the cut surface 20a at one end of the cut body 20 formed in the cutting step. In the present embodiment, the first adhesive is applied only to the rubber core 3 on the cut surface 20 a at one end of the cut body 20. The first adhesive 22 preferably has a higher viscosity than the second adhesive 24 described later. In the present embodiment, as an example, a cyanoacrylate adhesive (for example, Taoka Chemical Industries, Ltd.). Manufactured by Cyanobond (trade name) and the like.

  In the joining step, the application portion to which the first adhesive 22 is applied at one end of the cut body 20 is pressed against the central region of the cut surface at the other end to join. Specifically, the rubber core at one end to which the first adhesive 22 is applied is pressed against the rubber core at the other end to join.

  In this bonding step, as shown in FIG. 8, a substantially cylindrical holding member 50 is used, and one end of the cut body 20 is entered from one end of the holding member 50, and the one end is placed inside the holding member 50. Similarly, the other end portion of the cut body 20 to be accommodated enters from the other end side of the holding member 50 and is accommodated in the holding member 50. Either may be entered first or at the same time. Then, in a state where both the one end and the other end of the cut body 20 are housed in the holding member 50, the one end and the other end are joined via the first adhesive 22.

  As shown in FIG. 8, the holding member 50 formed in a longitudinal shape has a notch 51 formed in the side part over the entire longitudinal direction, and one end of the cut body 20 is connected to one end of the holding member 50. And the bonded portion 11 at one end of the cut body 20 is extended to the outside of the holding member 50 through the cutout portion 51. Further, the other end of the cut body 20 is inserted from the other end of the holding member 50, and the bonding portion 11 of the other end of the cut body 20 is also connected to the outside of the holding member 50 through the notch 51. Extend. Then, the one end and the other end of the cut body 20 are joined together via the first adhesive 22 while being held by the holding member 50.

(Attaching member (covering member) removal process)
The affixing member removing step corresponds to the covering member removing step, and includes an excision step and a peeling step. As shown in FIGS. 9 and 10, the excision step is performed by attaching the bonded portions 11 and 11 at one end and the other end of the cut body 20 extending to the outside of the holding member 50 in the circumferential direction of the ring body 30. It is the process of excision along. In FIG. 9, the excision position is conceptually shown by a one-dot chain line, and in FIG. 10, the state after excision is conceptually shown.

  Moreover, a peeling process is a process of peeling the adhesive tape 10 from the ring body 30 by which the bonding part was excised. After cutting each bonding part 11 and 11 like FIG. 10, the ring body 30 is removed from the holding member 50, and the adhesive tape 11 is peeled like FIG.

(Fuzz removal process)
After the peeling step, a fluff removal step is performed prior to the solidification step described later. The fluff removal step is a step of removing the fluff portion of the joint portion 30a in the ring body 30 formed by the bonding step. In the present embodiment, a thin fiber or the like extending to the side is cut by cutting means such as scissors. The fluff may be removed with an electric razor or a hair ball remover.

(Solidification process)
A solidification process is performed after a fuzz removal process. In the solidifying step, as shown in FIG. 13, the second adhesive 24 is applied to the outer periphery of the joint portion 30a in the ring body 30 formed in the bonding step, and the outer periphery of the joint portion 30a is solidified. When the solidification process is completed, a braided ring 1 with a rubber core as shown in FIG. 13 is obtained. As the second adhesive 24, one having a viscosity lower than that of the first adhesive 22 is used. In the present embodiment, as an example, a cyanoacrylate adhesive (for example, manufactured by Taoka Chemical Industry Co., Ltd.) is used. Among them, those having a viscosity lower than that of the first adhesive 22 are used. If an adhesive having a low viscosity is used in the solidification step in this way, it easily penetrates into the vicinity of the joint and solidification is suitably performed.
In the present embodiment, since the first adhesive 22 and the second adhesive 24 are the same cyanoacrylate adhesive (more specifically, the same cyanobond (trade name)), they are used in the solidifying step. When the second adhesive 24 to be infiltrated into the rubber core 3 (see FIG. 14) side, the two adhesives 22 and 24 are difficult to separate and are positively coupled to each other. Therefore, after the solidifying step, the vicinity of the joint portion of the braid 4 mainly joined by the second adhesive 24 and the vicinity of the joint portion of the rubber core 3 mainly joined by the first adhesive 22 are integrally formed. Bonding results in a very strong joint. In the present embodiment, the first adhesive 22 and the second adhesive 24 have different viscosities, but the same effect can be obtained even when these are the same adhesive. Of course. In addition, after this solidification process, you may make it remove fluff near a junction part with scissors, a cutter knife, an electric razor, a hair ball remover, etc.

  According to the embodiment, since the braided cord with the rubber core is cut after the covering portion is formed by winding the adhesive tape 10, the cutting surface is maintained by maintaining the covering with the adhesive tape 10 immediately after cutting. Fraying and fluffing are less likely to occur in the vicinity.

  The 2nd adhesive agent is apply | coated to the outer periphery of the junction part of the both ends in the ring body formed at the adhesion process, and the outer periphery of a junction part is solidified. Therefore, the joint portion of the ring body becomes stronger, and deterioration, fluffing, fraying and the like are less likely to occur on the outer periphery of the joint portion.

  Prior to the solidification step, the fuzzed portions of the joints at both ends are removed from the ring body formed by the bonding step. Therefore, fluffing can be further suppressed, and the aesthetics of the finally formed product is improved.

  Further, in the application step, the first adhesive is applied to the central region at a distance from the outer periphery on the cut surface of the one end portion of the cut body formed in the cutting step, and in the bonding step, the first adhesive at the one end portion is applied. The application part to which the adhesive is applied is pressed against the central area of the cut surface at the other end of the cut body. Therefore, when joining the both ends of a cut body, it becomes difficult for a 1st adhesive agent to adhere to the adhesive tape 10, and it becomes easy to perform a removal process.

  More specifically, in the application step, the first adhesive is applied to the rubber core on the cut surface of one end of the cut body formed in the cutting step, and in the bonding step, the first adhesive is applied. The rubber core at one end is pressed against the rubber core at the other end of the cut body and joined. Therefore, when joining the both ends of a cut body, the rubber cores of a cut surface are joined, and adhesion of the 1st adhesive agent with respect to a braid is suppressed. Accordingly, the first adhesive is less likely to adhere to the adhesive tape 10 and the removal process is facilitated.

  In addition, since the base end portion of the bonded portion is pressed and firmly bonded before the cutting step, the bonding with the adhesive tape 10 is firmly maintained in the portion near the cut surface after cutting by the cutting step. And fraying and fluffing are extremely difficult to occur.

  Further, in the cut body after the cutting step, the covering with the adhesive tape 10 is firmly maintained, fraying and fluffing hardly occur, and both ends of the cut body provided with the covering portion and the bonding portion can be suitably joined. It becomes. Moreover, the removal of the adhesive tape 10 after joining can also be performed suitably.

  The braided braid ring 1 with a rubber core obtained by the manufacturing method of the present embodiment is also of the same configuration as in FIG. 13, and is bonded to both ends of the braided braid 2 cut into a predetermined length to form a ring shape. Is formed. The rubber core-containing braid 2 that is the material of the rubber core-containing braid ring 1 is the same as that of the first embodiment shown in FIG. 14, and includes a rubber core 3 constituted by a rubber member, and the rubber core 3. It is comprised by the braid 4 to coat | cover. The rubber core 3 and the braid 4 thereof have elasticity, and as a result, the entire rubber core-containing braid ring 1 according to this embodiment is also rich in elasticity.

A method of manufacturing the rubber cored braid ring 1 (see FIG. 13) according to the second embodiment is roughly described as follows.
First, a braid containing rubber core 2 (see FIG. 14) similar to that of the first embodiment is prepared, and a covering portion forming step for forming the covering portion 115 as shown in FIG. 18 is performed, and thereafter, as shown in FIG. A cutting process is performed in which each covering portion 112 in the braided braid 2 is cut to form a cut body 125 as shown in FIG. In addition, the position to cut | disconnect should just be each coating | coated part 115 (part covered with the film member 110 in the braid 2 with a rubber core). Furthermore, as shown in FIGS. 24 and 25, the ring bodies (FIG. 11 and FIG. 11) are bonded by bonding the cut surfaces 125A at both ends of the cut body 125 formed in the cutting step via the first adhesive 122. A bonding process for forming a similar ring body) is performed, and then a covering member removing process for removing the covering member (film member 110) is performed. Finally, a braided ring 1 with a rubber core as shown in FIG. 13 is formed. Hereinafter, each process etc. are demonstrated concretely.

(Cut process)
In the present embodiment, the cutting step is performed prior to the covering portion forming step.
As shown in FIG. 15, this cutting process is performed by converting the rubber cored braid 2 having the same internal configuration as that of the first embodiment (see FIG. 14) to the length of the finished product (that is, the rubber cored braid ring shown in FIG. 13). This is a step of forming the first cut body 120 cut slightly longer than the length (1). In addition, the cutting method in a cutting process should just be a method which can cut | disconnect the braid 2 with a rubber core, may use a cutting machine etc., and may use cutting tools, such as a scissor and a cutter.

(Coating part forming step)
When the cutting process is completed, a covering portion forming process is performed.
In the covering portion forming step, the heat shrinkability is longer in the vicinity of both ends of the rubber cored braid 2 (ie, the first cut body 120) formed in the cutting step of FIG. The film member 110 is wound as shown in FIG. At that time, as shown in FIG. 17, both end portions 110D and 110D of the heat-shrinkable film member 110 are extended to the side of the braided cord 2 with rubber core, and the extending both end portions 110D and 110D are extended. Are superimposed on each other. In the example of FIG. 17, the covering member 115 is formed by winding the film member 110 so that the end portions 120 </ b> A and 120 </ b> B of the first cut body 120 are completely covered. When coated in this manner, the amount of braid with rubber core removed in the cutting step described later can be reduced, but the end portions 120A and 120B of the first cut body 120 are the outer end portions of the film members 110 and 110, respectively. The end portions 120A and 120B may protrude beyond the outer end portions of the film members 110 and 110, respectively.

  After that, as shown in FIG. 18, a part (specifically, a part near the outer peripheral surface of the first cut body 120) of the overlapping parts of the film member 110 is melted to form the welded part 111. When the welded portion 111 is formed, the film member 110 is wound around both end portions of the first cut body 120 as shown in FIG. As the heat-shrinkable film member 110, a shrink film made of PP (polypropylene), PVC (vinyl chloride), PET (polyethylene terephthalate), or the like can be used. The material of the film member 110 is not limited to these, and various resin materials having heat shrinkability can be used.

  After the film member 110 is wound around the both ends of the first cut body 120 as shown in FIG. 18, a heating step of heating the film member 110 as shown in FIG. 19 is performed. The heating step is a step of heating the covering member disposed around the braided cord 2 with the rubber core. Specifically, the film member 110 is heated by the heater while the film member 110 is wound around the braided cord 2 with the rubber core. Then, the film member 110 is contracted. When the film member 110 is contracted, the vicinity of the end portions 120 </ b> A and 120 </ b> B of the first cut body 120 is tightened by the film member 110. In this state, as shown in FIG. 21, the film member 110 is tightly wound around the braided cord 2 with rubber core substantially without loosening. In the heating step, only the vicinity of the film member 110 may be heated, or the entire first cut body 120 may be heated (for example, the first cut body 120 is passed through a tunnel-shaped heating furnace). The whole thing can be heated).

(Cutting process)
In the cutting step, a part of the covering portion 115 is cut to each braided cord 2 with the covering portion 115 formed, and the covering portion 115 is provided at both ends as shown in FIG. A body 125 is formed. In the present embodiment, a predetermined cutting position as shown by a broken line C in FIG. 20 (specifically, a position where the film member 110 is disposed and a position inside the end portions 120A and 120B) is cut. Become. The second cut body 125 corresponds to a “cut body” in the claims, and both end portions 125A and 125B of the second cut body 125 are configured at the end portions of the braided cord 2 with a rubber core. The cut surface is exposed. The cutting may be performed by a cutting machine or the like, or may be performed by an instrument or a machine having a cutting tool (such as a cutting tool such as scissors or a cutter knife).

(Smoothing process)
In the present embodiment, after the above-described cutting step, a smoothing step for smoothing the cut surface is performed prior to the bonding step (described later). In this smoothing step, the fluffed portion (see the fluffed portion 101 in FIG. 23) and the like in the vicinity of the cut surface is removed at both end portions 125A and 125B of the second cut body 125 formed in the cutting step to smooth the cut surface. This is a process for realizing the process. Further, since there is a possibility that the braid 4 protrudes from the rubber core 3 by the cutting process, in the case of such a protrusion, the braid 4 is partially cut away or the braid 4 and the rubber core 3 are partially cut away. A process of aligning the end and the end of the rubber core 3 is performed. In the present embodiment, the thin fibers extending to the side and the protruding portion of the braid 4 are cut off by cutting means such as scissors and a cutter knife. Moreover, in this embodiment, since the coating | coated part 115 is formed without joining with respect to the braid 2 with a rubber core with a heat-shrinkable material, when the film member 110 slip | deviates by a cutting process, the braid 2 with a rubber core is formed. Since the film member 110 may protrude from the end portion, in some cases, a part of the film member 110 is removed with scissors or the like, and the entire cut surface is smoothed. In this smoothing step, the fluffed portion or the like may be cut out with an electric razor or a hair ball remover to smooth the cut surface.

(Adhesion process)
An adhesion process is performed after the above-mentioned smoothing process. The adhesion process is configured by an application process and a bonding process. In the application step, the first adhesive 122 is applied on the cut surface of the one end portion 125A of the second cut body 125 formed in the cutting step. As the first adhesive 122, it is desirable to use one having a higher viscosity than a second adhesive (second adhesive similar to that in the first embodiment) described later. A cyanoacrylate adhesive similar to the first adhesive (for example, cyanobond (trade name) manufactured by Taoka Chemical Co., Ltd.) is used. In the coating process of the present embodiment, the entire cut surface is applied by attaching the entire cut surface of the one end portion 125A of the second cut body 125 formed in the cutting step to the adhesive layer Q having a larger area than the cut surface. The first adhesive 122 is applied to the substrate. Specifically, one end portion 125A enters substantially perpendicularly to the surface of the adhesive layer Q, and the one end portion 125A is attached to the adhesive layer Q. As a result, a layered adhesive is placed on the entire cut surface of the one end 125A as shown in FIG.

  In the joining step, as shown in FIG. 25, the one end 125A applied with the first adhesive 122 in the cut body 125 is pressed against the cut surface of the other end 125B (see FIG. 22) to join. Since this bonding step uses the same method as in FIG. 8, it will be described with reference to FIG. Specifically, a substantially cylindrical holding member 50 is used, and one end portion 125A of the second cut body 125 is entered from one end side of the holding member 50, and the one end portion 125A is accommodated in the holding member 50. Similarly, the other end portion 125 </ b> B of the cut body 125 enters from the other end side of the holding member 50 and is stored inside the holding member 50. Either may be entered first or at the same time. Then, in a state where the one end portion 125 </ b> A and the other end portion 125 </ b> B of the second cut body 125 are both housed in the holding member 50, the one end portion and the other end portion are joined via the first adhesive 122. .

  As shown in FIG. 8, the holding member 50 formed in a longitudinal shape is formed with a notch 51 extending in the entire longitudinal direction on the side portion, and in this embodiment, the one end 125 </ b> A of the second cut body 125 is also formed. While inserting from the one end side of the holding member 50, both end portions 110 </ b> D in the vicinity of the one end portion 125 </ b> A of the second cut body 125 are extended to the outside of the holding member 50 through the notch portion 51. Further, the other end 125B of the second cut body 125 is inserted from the other end of the holding member 50, and both end portions 110D of the other end 125B are also connected to the outside of the holding member 50 through the notch 51. Extend. Then, the one end portion 125A and the other end portion 125B of the second cut body 125 are joined together via the first adhesive 122 while being held by the holding member 50. In addition, although the example joined using the holding member 50 is shown here, it is not necessary to use a holding member. That is, as shown in FIG. 25, the one end 125A coated with the first adhesive 122 may be pressed and joined to the other end 125B as it is.

(Removal process)
The removal process includes an excision process and a peeling process, and the same method as in the first embodiment is used for both. Therefore, description will be made with reference to FIGS. 9 and 10 shown in the first embodiment. In FIGS. 9 and 10, the covering portion is formed by the adhesive tape 10, but in the present embodiment, this will be described by replacing it with the film member 110. The removing step is a step of cutting the both end side portions 110 </ b> D that extend to the outside of the holding member 50 in the film member 110 along the circumferential direction of the ring body 30. Specifically, both ends 110D are removed in the same manner as in FIG. 10 by cutting the vicinity of the one-dot chain line shown in FIG. 9 with cutting means such as scissors or a cutter knife.

  Further, the peeling step is a step of peeling the film member 110 from the ring body 30 from which both end portions 110D are cut from the film member 110. Specifically, as in FIG. 10, after cutting both end portions 110 </ b> D, the ring body 30 is removed from the holding member 50 and the film member 110 is peeled off as in FIG. 11. In addition, in this embodiment, since it becomes the structure which heat-shrinks and tightens the film member 110, it is the structure by which the film member 110 is not affixed with respect to the braid 2 with a rubber core. Therefore, it can be easily and satisfactorily peeled off. More specifically, for example, if the ring body 30 is slightly stretched to reduce the diameter of the braided portion with rubber core, the gap between the outer peripheral surface of the film member 110 and the braided cord with rubber core 2 and the inner peripheral surface of the film member 110 is reduced. A gap can be formed. If such a gap is formed, it becomes easy to insert a cutting tool such as scissors, and the work can be facilitated.

(Fuzz removal process)
After the peeling step, a fluff removal step is performed prior to the solidification step described later. Since the fuzz removal process is the same as the fuzz removal process of Embodiment 1, it will be described with reference to FIG. Specifically, in the ring body 30 formed by the bonding process, the fluffed portion of the joint portion 30a (in this embodiment, the boundary portion excluding the film member 110 by joining the one end portion 125A and the other end portion 125B) is removed. It is a process to do. In the present embodiment, a thin fiber or the like extending to the side is cut by cutting means such as scissors. The fluff may be removed with an electric razor or a hair ball remover.

(Solidification process)
After the fluff removal step, the same solidification step as in the first embodiment is performed. As in FIG. 13, the solidifying step is a joint 30a in the ring body 30 formed in the bonding step (in this embodiment, the boundary portion excluding the film member 110 by joining the one end 125A and the other end 125B). The 2nd adhesive agent 24 similar to Embodiment 1 is apply | coated to the outer periphery of this, and the outer periphery of the junction part 30a is solidified. When the solidification process is completed, a braided ring 1 with a rubber core as shown in FIG. 13 is obtained. As the second adhesive 24, one having a viscosity lower than that of the first adhesive 122 is used. In the present embodiment, as an example, a cyanoacrylate adhesive (for example, manufactured by Taoka Chemical Industry Co., Ltd.) is used. Among them, those having a viscosity lower than that of the first adhesive 122 are used. If an adhesive having a low viscosity is used in the solidification step in this way, it easily penetrates into the vicinity of the joint and solidification is suitably performed. In the present embodiment, the first adhesive 122 and the second adhesive 24 have different viscosities, but the same effect can be obtained even when the same adhesive is used. Of course. In addition, after this solidification process, you may make it remove fluff near a junction part with scissors, a cutter knife, an electric razor, a hair ball remover, etc.

<Embodiment 3>
Embodiment 3 of the present invention will be described with reference to the drawings.
FIG. 26 is an explanatory view showing a covering portion forming step in Embodiment 3, and FIG. 27 is an enlarged perspective view showing the appearance of the covering portion. Moreover, FIG. 28 is explanatory drawing which shows the heating process of Embodiment 3, and FIG. 29 is explanatory drawing which shows the cutting process of Embodiment 3. FIG.

(Cut process)
In the third embodiment, the same cutting process as in the second embodiment is used. After the cutting step, a covering portion forming step as shown in FIGS. 26 and 27 is used.
(Coating part forming step)
In this embodiment, as shown in FIGS. 26 and 27, the covering member is constituted by a heat-shrinkable tube member 130. In the covering portion forming step of the present embodiment, the tube members 130 are respectively arranged around the first cut body 120 as shown in FIGS. In the example of FIG. 26, the covering member 115 is formed by covering the tube members 130 so that the end portions 120A and 120B of the first cut body 120 are completely covered. When covered in this manner, the amount of braid with rubber core removed in the cutting step described later can be reduced, but the end portions 120A and 120B of the first cut body 120 are the outer end portions of the tube members 130 and 130, respectively. The end portions 120A and 120B may protrude beyond the outer end portions of the tube members 130 and 130, respectively. As the heat-shrinkable tube member 130, a shrink film made of PP (polypropylene), PVC (vinyl chloride), PET (polyethylene terephthalate), or the like can be used. The material of the tube member 130 is not limited to these, and various resin materials having heat shrinkability can be used.

After covering the tube member 130 on both ends of the first cut body 120 as shown in FIGS. 26 and 27, a heating step of heating the tube member 130 as shown in FIG. 28 is performed. The heating step is a step of heating the covering member disposed around the braided cord 2 with the rubber core. Specifically, the tube member 130 is heated by the heater while the tube member 130 is covered around the braided cord 2 with the rubber core. Then, the tube member 130 is contracted. When the tube member 130 is contracted, the vicinity of the end portions 120A and 120B of the first cut body 120 is tightened by the tube member 130, similarly to the film member 110 of the second embodiment. In this state, the rubber cored braid 2 is firmly tightened by the tube member 130 without being loosened. In the heating process, only the vicinity of the tube member 130 may be heated, or the entire first cut body 120 may be heated (for example, the first cut body 120 may be passed through a tunnel-shaped heating furnace). The whole thing can be heated).
(Cutting process)
In the cutting step, a part of the covering portion 115 is cut to each of the braided braids 2 with the covering portion 115 formed, and the covering portions 115 are provided at both ends as shown in FIG. A body 125 is formed. In the present embodiment, a predetermined cutting position (specifically, a position where the tube 130 is disposed and a position inside the ends 120A and 120B) as shown by a broken line in the upper diagram of FIG. 29 is cut. Become. The second cut body 125 corresponds to a “cut body” in the claims, and both end portions 125A and 125B of the second cut body 125 are configured at the end portions of the braided cord 2 with a rubber core. The cut surface is exposed. The cutting may be performed by a cutting machine or the like, or may be performed by an instrument or a machine having a cutting tool (such as a cutting tool such as scissors or a cutter knife).
(Smoothing process)
In the present embodiment, after the above-described cutting step, a smoothing step for smoothing the cut surface is performed prior to the bonding step (described later). Since this smoothing step is the same as the smoothing step of the second embodiment, it will be described with reference to FIG. Specifically, in both end portions 125A and 125B of the second cut body 125 formed in the cutting step, the fuzzed portion in the vicinity of the cut surface (the fuzzed portion similar to the fuzzed portion 101 in FIG. 23) and the like are removed to obtain a cut surface. It is the process of aiming at smoothing. Further, since there is a possibility that the braid 4 protrudes from the rubber core 3 by the cutting process, in the case of such a protrusion, the braid 4 is partially cut away or the braid 4 and the rubber core 3 are partially cut away. A process of aligning the end and the end of the rubber core 3 is performed. In the present embodiment, the thin fibers extending to the side and the protruding portion of the braid 4 are cut off by cutting means such as scissors and a cutter knife. Moreover, in this embodiment, since the coating | coated part 115 is formed without joining with respect to the braid 2 with a rubber core with a heat-shrinkable material, when the tube member 130 shifts | deviates by a cutting process, the braid 2 with a rubber core is formed. Since the tube member 130 may protrude from the end portion, in some cases, a part of the tube member 130 is removed with scissors or the like, and the entire cut surface is smoothed. In this smoothing step, the fluffed portion or the like may be cut out with an electric razor or a hair ball remover to smooth the cut surface.

(Adhesion process)
An adhesion process is performed after the above-mentioned smoothing process. The bonding process is constituted by an application process and a bonding process. Since the application process is the same as that of the second embodiment, the description will be made with reference to FIGS. 24 and 25. In this application process, the cutting surface of the one end portion 125A of the second cut body 125 formed in the cutting process is used. The first adhesive 122 is applied. As the first adhesive 122, it is desirable to use one having a higher viscosity than a second adhesive (second adhesive similar to that in the first embodiment) described later. A cyanoacrylate adhesive similar to the first adhesive (for example, cyanobond (trade name) manufactured by Taoka Chemical Co., Ltd.) is used. In the coating process of the present embodiment, the entire cut surface of the one end portion 125A of the second cut body 125 formed in the cutting process is applied to the adhesive layer Q having a larger area than the cut surface, as in the second embodiment. By attaching, the 1st adhesive agent 122 is apply | coated to the whole cut surface. Specifically, one end portion 125A enters substantially perpendicularly to the surface of the adhesive layer Q, and the one end portion 125A is attached to the adhesive layer Q. As a result, as shown in FIG. 25, the layered adhesive is placed on the entire cut surface of the one end portion 125A (FIG. 25 and the present embodiment are different from the first example in that the film member 110 is replaced with the tube member 130. The application method and application mode of the adhesive 122 are the same).
In the joining step, as shown in FIG. 25, the one end 125A applied with the first adhesive 122 in the cut body 125 is pressed against the cut surface of the other end 125B (see FIG. 22) to join. Since this bonding step uses the same method as in FIG. 8, it will be described with reference to FIG. Specifically, a substantially cylindrical holding member 50 is used, and one end portion 125A of the second cut body 125 is entered from one end side of the holding member 50, and the one end portion 125A is accommodated in the holding member 50. Similarly, the other end portion 125 </ b> B of the cut body 125 enters from the other end side of the holding member 50 and is stored inside the holding member 50. Either may be entered first or at the same time. Then, in a state where the one end portion 125 </ b> A and the other end portion 125 </ b> B of the second cut body 125 are both housed in the holding member 50, the one end portion and the other end portion are joined via the first adhesive 122. . The tube member 130 according to the present embodiment does not need to be extended from the notch 51 because there is no such thing as the bonded portion 11 of the first embodiment or the both end portions 110D of the second embodiment. . In addition, although the example joined using the holding member 50 is shown here, it is not necessary to use a holding member. That is, the one end 125A (that is, the same application manner as in FIG. 25) to which the first adhesive 122 is applied may be pressed and joined to the other end 125B as it is.
(Removal process)
In the removing step, a part of the tube member 130 in the ring body 30 (which is obtained by replacing the attaching member of the ring body 30 in FIG. 8 with the tube member 130) having the same configuration as in FIG. The tube member 130 is removed by cutting in the direction. In the present embodiment, since the tube member 130 is heat-shrinked and tightened, the tube member 130 is not attached to the braid 2 with a rubber core. Therefore, it can be easily and satisfactorily peeled off. More specifically, for example, if the ring body 30 is slightly stretched to reduce the diameter of the braided portion with rubber core, the outer peripheral surface of the tube member 130, the braided cord 2 with rubber core, and the inner peripheral surface of the tube member 130 A gap can be formed between them. If such a gap is formed, it becomes easy to insert a cutting tool such as scissors, and the work can be facilitated.
(Fuzz removal process)
After the removing step, a fluff removing step is performed prior to the solidifying step described later. Since the fuzz removal process is the same as the fuzz removal process of Embodiment 1, it will be described with reference to FIG. Specifically, in the ring body 30 formed by the bonding process, the fluffed portion of the joint portion 30a (in this embodiment, the boundary portion excluding the tube member 130 by joining the one end portion 125A and the other end portion 125B) is removed. It is a process to do. In the present embodiment, a thin fiber or the like extending to the side is cut by cutting means such as scissors. The fluff may be removed with an electric razor or a hair ball remover.
(Solidification process)
After the fluff removal step, the same solidification step as in the first embodiment is performed. As in FIG. 13, the solidifying step is a joint 30a in the ring body 30 formed in the bonding step (in this embodiment, the boundary portion excluding the film member 110 by joining the one end 125A and the other end 125B). The 2nd adhesive agent 24 similar to Embodiment 1 is apply | coated to the outer periphery of this, and the outer periphery of the junction part 30a is solidified. When the solidification process is completed, a braided ring 1 with a rubber core as shown in FIG. 13 is obtained. As the second adhesive 24, one having a viscosity lower than that of the first adhesive 122 is used. In the present embodiment, as an example, a cyanoacrylate adhesive (for example, manufactured by Taoka Chemical Industry Co., Ltd.) is used. Among them, those having a viscosity lower than that of the first adhesive 122 are used. If an adhesive having a low viscosity is used in the solidification step in this way, it easily penetrates into the vicinity of the joint and solidification is suitably performed. In the present embodiment, the first adhesive 122 and the second adhesive 24 have different viscosities, but the same effect can be obtained even when the same adhesive is used. Of course. In addition, after this solidification process, you may make it remove fluff near a junction part with scissors, a cutter knife, an electric razor, a hair ball remover, etc.
