Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a dust removal adhesive tape roll used to remove dust adhering to a floor surface or clothing by utilizing the adhesiveness of the adhesive tape.

[0002]

[Prior art]

 Conventionally, a winding body such as an insulating tape for wiring or a cellophane tape for packaging and stationery has a structure in which an adhesive layer is placed inside and wound around a paper core, while the adhesive layer is used in reverse. To the outside, and attach it to large and small rollers according to the size of the roll, and use the adhesiveness of the adhesive tape to clean the floor and wear clothes. There is known a dust remover used for such purposes as dropping adhered dust.

In these dust removers, when a large amount of dust adheres to the surface of the pressure-sensitive adhesive layer located at the outermost layer and its ability deteriorates, the dust removing tool is used and stripped off to expose the surface of a new pressure-sensitive adhesive layer. It can be used for a long period of time. In order to make this stripping operation easy, it is usual to make a cut in the width direction about every turn of the wound body (Japanese Utility Model Publication No. 52-3272, Japanese Utility Model Publication No. 2-20984). See the public notice).

[0004]

[Problems to be solved by the present invention]

 In fact, when a large amount of dust adheres to the outermost pressure-sensitive adhesive layer, it is difficult to find a cut (hereinafter referred to as a mouthpiece position) that is the peeling start position for peeling and removing the outermost layer. There was a problem. However, the adhesive cleaner described in JP-B-2-20984 aims at facilitating the "unwinding" by providing the parts not coated with the adhesive on both sides in the width direction. There was also a problem that it was difficult to clean if the adhesive layer was not formed over the entire width direction because the constant width on both sides of the was not available.

The present invention solves the above-mentioned drawbacks of the prior art, and provides a roll of a dust-removing adhesive tape that allows the user to easily find the edge position even when a large amount of dust adheres to the adhesive layer. It was made for the purpose of doing.

[0006]

[Means for Solving the Problems]

 According to the present invention, an "adhesive tape having a pressure-sensitive adhesive layer formed on one surface of a strip-shaped substrate and a back surface subjected to a peeling treatment is wound with the pressure-sensitive adhesive layer on the outer side, and the tape is stretched in the width direction almost every turn. A roll of a dust-removing pressure-sensitive adhesive tape having a cut line formed in the cut line, wherein a colored band is formed along the cut line.

That is, the essence is that a tinted position can be easily found by visual observation by forming a colored band along the cut.

As a means for forming such a colored band, it is preferable to form it by coloring the release agent used for the cut punching blade. In this way, a special mechanical device is not required, and the colored strip is formed by an extremely simple operation of simply coloring the release agent which is usually used for the punching blade for forming a slit.

[0009] Usually, the cut is formed by attaching a punching blade 7 to a press P as shown in Fig. 2 and forming a cut on the lower mounting table by a roll 8 of dust removing adhesive tape (two points). (Shown by the chain line) and the press machine is operated to move the punching blade 7 up and down along the guide 9 to form a predetermined pitch and dimension corresponding to the punching blade 7 in the width direction of the roll 8. Perforation-shaped cuts are made.

At this time, since the adhesive and dust are likely to adhere to the punching blade 7 and the punching work cannot be continuously and smoothly performed as it is, usually, when the punching is performed 2 to 3 times, the punching is temporarily stopped. For example, apply a silicone-based release agent solution to the cutting blade 7 and the guide 9, and then perform blanking several times to remove the adhesive and dust adhering to the cutting blade 7 and the guide 9, and after that, The method of restarting punching is adopted.

Ink or pigment is added to the release agent used at this time to color the release agent into an appropriate color. Then, the colored release agent applied to the punching blade 7 or the guide 9 permeates into the adhesive layer or the core along the slit at the time of punching after restarting, and a colored strip is formed along the slit. It is.

The release agent used is mainly the above-mentioned silicone release agent, that is, a silicone resin having dimethylpolysiloxane as a main component and excellent in releasability and water repellency. And emulsion type. Other examples include stearic acid salts, trifluoroethylene, wax and the like.

The ink or pigment to be colored is not particularly limited, and usually, the addition amount may be about 1% with respect to 100 parts by weight of the release agent.

In the present invention, since the cut is provided on the wound adhesive tape, the colored band is formed on the adhesive layer, the base material, or both. However, if the pressure-sensitive adhesive has excellent transparency, the base material may be soaked deeply into the base material even if the release agent is not soaked into the base material.

Therefore, the base material of the pressure-sensitive adhesive tape used in the present invention is not particularly limited, and those conventionally used can be used as they are, and Japanese paper, cellophane, cloth, synthetic resin foam, etc. can be mentioned. . However, in the case of a synthetic resin film, the capillary phenomenon itself cannot occur. Therefore, if the base material is colored, it is necessary to select a combination of an adhesive agent and a release agent that can be colored reliably.

Also, the adhesive of the adhesive tape used in the present invention is not particularly limited, but as described above, it has an affinity for the release agent used for the punching blade and is excellent in colorability and dyeability. Better to use.

[Action]

 Since the colored strip is formed along the cut line in the roll of the dust-removing adhesive tape of the present invention, it is possible to easily find the edge position.

Then, the pressure-sensitive adhesive layer 3 is wound around the paper winding core 4 to form a wound body R.

Reference numeral 5 is a cut provided in the width direction approximately every one turn of the wound body R, and colored bands 6 are formed along both sides of the cut 5. The cut 5 is made by the press machine shown in FIG.

Therefore, the release agent solution was mixed with 100 parts by weight of the release agent solution in advance, and was mixed with an X stamper (# dye-based ink manufactured by Shachihata Kogyo Co., Ltd.) as a colorant to be colored red. I used the one.

Then, as in the case of the normal punching operation, the normal punching operation is carried out three times in succession and once stopped, and the release agent solution soaked in the urethane foam is cut with the punching blade 7 and the guide. Then, the sample was applied to No. 9 and the blank was punched 3 times, and then the normal punching operation was repeated 3 times continuously to obtain a total of 6 samples of the dust-removing adhesive tape roll. On both sides of the cut 5 of these rolls R, colored bands 6 having a thickness of 0.5 mm were formed in the entire width direction.

Further, the six samples of the adhesive tape roll thus obtained were sequentially mounted on the floor cleaning cleaner C shown in FIG. 3, and the test dust consisting of lint was distributed evenly on the outermost layer. When the cuts, that is, the positions of the edges were visually searched for after the attachment, all the samples could be found immediately and could be peeled and removed normally.
