Description

[0001]
[Technical field to which the invention belongs]
The present invention relates to an adhesive double-sided adhesive tape for bonding a tubular tire for a bicycle and a method for bonding to a tubular rim.
[0002]
[Prior art]
Conventionally, as shown in FIG. 4, in order to bond a bicycle tubular tire (hereinafter simply referred to as a tire) 5 to a tubular rim (hereinafter simply referred to as a rim) 6, a viscous liquid or paste called rim cement is used. The adhesive 7 is applied to the rim surface (the outer periphery where the tire is mounted), and further applied to the tire side 6a surface, then the tire is mounted on the rim, and the rim cement 7 is naturally cured to bond the two together. It is common.
[0003]
[Problems to be solved by the invention]
The conventional method of applying the rim cement and bonding the tire to the rim has many contents that require experience such as the application of the rim cement, and it is difficult for anyone to obtain stable adhesiveness.
That is, uneven coating occurs, and individual differences occur in the finish. Since it is a liquid or paste-like adhesive, it adheres to areas other than the bonded part of the tire when the tire is mounted, and it becomes dirty with the adhesive and the aesthetic appearance is impaired. Similarly, there are problems such as protruding adhesive when the tire is mounted. There is a possibility that the brake performance may be impaired by protruding from the brake surface of the rim. In order to remove the protruding adhesive, it is not good for the working environment such as using a solvent. Since it is liquid and pasty, it is difficult to form a rim and an adhesive layer that moves when pressure is applied and absorbs irregularities on the adhesion surface of the tire. In addition, it is difficult to perform the adjustment work of aligning the tire running surface called “centering” after the tire mounting to the center of the rim with respect to the traveling direction in a state where adhesion or adhesion is not stable. In addition, this work becomes a secondary factor such as rim cement protrusion. When changing tires, it is necessary to scrape or use a solvent to remove the hardened rim cement, but the hardened rim cement does not easily fall off and the rim cement coated surface on the rim cannot be restored. There are disadvantages.
[0004]
The object of the present invention is to eliminate such drawbacks and to enable anyone to easily and securely bond a tire to a rim without protruding adhesive.
[0005]

DETAILED DESCRIPTION OF THE INVENTION
A non-woven fabric as a support for the adhesive layer, the adhesive layer is made of an acrylic closed-cell adhesive, and the adhesive layer has sufficient strength to prevent it from being damaged during installation. An adhesive double-sided tape for bonding tubular tires for bicycles constructed on paper.
[0011]
【Example】
Hereinafter, an adhesive double-sided adhesive tape for a bicycle tubular tire (hereinafter simply referred to as a tire) according to the present invention will be described with reference to the drawings shown in FIG. In the middle of the first pressure-sensitive adhesive surface 2a and the second pressure-sensitive adhesive surface 2b of the adhesive layer 2 formed to the required thickness, and corresponding to the first pressure-sensitive adhesive surface 2a and the second pressure-sensitive adhesive surface 2b, The adhesive double-sided adhesive tape 4 includes a non-woven fabric 3 as a support.
[0012]
Next, with reference to FIG. 2 showing an example of a method of bonding the tire 6 to a tubular rim (hereinafter simply referred to as a rim) 5 with the adhesive double-sided adhesive tape 4, oil and dust on the bonding surface 5a of the rim 5 will be described. Next, the adhesive double-sided adhesive tape 4 is attached to a valve hole (not shown) as a starting point, so that the valve hole is confirmed and the first adhesive surface 2a is pressed against the rim 5 from the side of the valve hole. Affix it to the rim 5 in the same way as affixing office tape. At this time, the release paper 1 does not stretch because it has sufficient strength to resist pulling. Therefore, the adhesive layer 2 does not stretch and does not decrease in thickness, and adheres to the tire. It is configured so that a sufficient adhesion effect can be exhibited without lowering the properties. Then, when the adhesive double-sided adhesive tape 4 goes around the rim 5 and approaches the valve hole, the adhesive double-sided adhesive tape 4 is cut at the arrival point. At this time, both end portions of the release paper 1 are peeled off by a required length and pulled out and placed outside the rim 5.
[0013]
Next, after dust on the adhesion surface side of the tire 6 to be mounted is removed, a valve (not shown) of the tire 6 is inserted into a valve hole of the rim 5 and the tire 6 is mounted on the rim 5. There is no stickiness of the rim cement, and the tire 6 and the rim 5 are not contaminated and can be easily mounted.
[0014]
Next, lightly air is applied to the tire 6, and the center is put out so that the cotton part 6 a serving as the bonding surface of the tire 6 is securely on the rim 5. Then, the tire 6 is lifted upward in a state where some air is contained, and is pulled out by holding the rim 5 and one end of the release paper 1 drawn out of the tire 6. After pulling out, it sequentially moves to a new location, lifts the tire 6 at that portion upward, and pulls out the corresponding release paper 1. Since the release paper 1 has sufficient strength, it can be pulled out smoothly without being damaged unless it is applied to an acute angle surface.
[0015]
Thus, by confirming the center of the tire 6 again and pressing it against the rim 5, the thickness of the adhesive layer 2 due to foaming enters the irregularities of the cotton portion 6 a of the tire 6, thereby exhibiting an adhesive effect. Then, air is introduced up to an appropriate pressure of the tire 6 and the mounting of the tire 6 is completed.
[0016]
【The invention's effect】
Since the adhesive double-sided adhesive tape for tubular bicycle tires and the method for adhering to the tubular rim of the present invention are as described above, since it is a tape-like adhesive, anyone can easily attach it to the rim surface. An adhesive layer can be formed.
[0017]
Next, since the tape itself is an adhesive and is independently foamed to have thickness and flexibility, an adhesive layer having excellent sealing properties can be easily formed while absorbing the unevenness that the adhesive surface can have. Therefore, the adhesion between the rim and the tire is ensured.
[0018]
When there is an extreme unevenness of the bonding surface due to the product difference between the rim and the tire, it is possible to easily form a necessary and sufficient thickness of the adhesive layer by stacking and bonding the tape. It will be certain.
[0019]
Since the adhesive uses a material such as acrylic having excellent heat resistance and weather resistance, it is a tape that can maintain stable adhesiveness even under severe use conditions of tubular tires that run at high pressure and high speed.
[0020]
Since it is a product combining a self-foamed adhesive and a nonwoven fabric as a support, the width of the tape at the time of application does not change, and it adheres only to the part necessary for adhesion.
[0021]
It does not stick out like a liquid or paste, and does not disturb the aesthetics by soiling the tire or rim.
[0022]
Since no protrusion occurs, no removal work is required.
[0023]
As a mounting method, a method is adopted in which a tape is attached, a tire is mounted, a centering is performed, and then a release paper (paper or resin) is peeled off. Therefore, reliable positioning can be performed, and there is no fear of getting dirty and it is easy.
[0024]
The surface on which the tape on the rim is attached can be easily restored simply by removing the tape remaining on the rim surface, such as when changing tires.
[0025]
Apply tape to the rim-> Install the tire-> Pull out the release paper-> Apply high pressure (recommended maximum tire pressure) to the tire to bring the adhesive surface into close contact. The tire bonding is completed neatly and quickly just by the above work.
[0026]
Therefore, the adhesive double-sided adhesive tape for tubular bicycle tires and the method for adhering to the tubular rim according to the present invention have the above-mentioned epoch-making effects as compared with the general adhesion by the conventional rim cement. is there.
