Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to a cleaning adhesive roll.

[0002]

2. Description of the Related Art As an adhesive roll for cleaning, at the manufacturing stage,
Some long rolls obtained by laminating a multi-layered pressure-sensitive adhesive sheet are cut with a cutter. In this pressure-sensitive adhesive roll, in the use stage, after dust is adhered and captured on the pressure-sensitive adhesive sheet on the surface layer of the pressure-sensitive adhesive roll, the used pressure-sensitive adhesive sheet on the surface layer is peeled off and removed, and a fresh pressure-sensitive adhesive sheet is generated on the surface layer of the pressure-sensitive adhesive roll.

[0003]

When a long roll body is cut by a cutter in a production step of the adhesive roll, the adhesive layer of the upper adhesive sheet in the long roll body is moved to a lower layer side by a blade surface of the cutter. When pressed, the adhesive layers of the upper and lower pressure-sensitive adhesive sheets are in contact with each other and tend to adhere to each other. In such a pressure-sensitive adhesive roll, the pressure-sensitive adhesive sheet on the upper layer side and the pressure-sensitive adhesive sheet on the lower layer side on which the cut short roll body is layered are adhered to each other at the cut end face of the short roll body. Then, at the stage of using the pressure-sensitive adhesive roll, the pressure-sensitive adhesive sheet on the surface layer is difficult to peel off from the pressure-sensitive adhesive sheet on the lower layer side, and the pressure-sensitive adhesive sheet on the surface layer may be broken from the end face.

[0004] An object of the present invention is to provide a cleaning adhesive roll produced by cutting a long roll body with a cutter, so that the upper adhesive sheet and the lower adhesive sheet are prevented from sticking at the cut end faces, In the use stage, the pressure-sensitive adhesive sheet on the surface layer side is easily peeled off and hardly torn.

[0005]

The invention according to claim 1 is a cleaning adhesive roll comprising a short roll obtained by cutting a long roll obtained by laminating a multi-layer adhesive sheet with a cutter,
The powder was provided to the cutting part by the cutter.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A cleaning tool 10 shown in FIG.
The adhesive roll 20 is rotatably inserted into the support shaft 12 connected to the support 1, and the adhesive roll 20 is rolled on the floor with the handle 11 to remove dust on the floor from the adhesive roll 20.
Is adhered and captured on the pressure-sensitive adhesive sheet 21 of the surface layer. 2
Reference numeral 2 denotes a core, and 22A denotes bearings provided on the inner periphery of both ends of the core 22.

As shown in FIGS. 2 and 5, a pressure-sensitive adhesive roll 20 is formed by laminating a multi-layered pressure-sensitive adhesive sheet 21 on the outer periphery of a core 22 and, when the pressure-sensitive adhesive surface of the pressure-sensitive adhesive sheet 21 faces outward, a release paper on the outermost layer. A long roll body 24 provided with 23 comprises a short roll body 25 cut by a rotary cutter 30. At the manufacturing stage, the adhesive roll 20 is provided with powder 32 such as a sicker roll fed from a powder supply nozzle 31 to each of the cut portions at both ends by a cutter 30 to form a short roll body 25 (FIG. 5). . Instead of the rotary cutter 30,
A pushing cutter 30A may be used (FIG. 6). The adhesive roll 20 (short roll body 25) preferably has the powder 32 on the cut end surface even in the use stage (FIG. 2).

The pressure-sensitive adhesive roll 20 is a single sheet of the pressure-sensitive adhesive sheet 21 of one layer extending from one end to the other end in the roll axis direction, and is diagonally wound along a diagonal winding direction obliquely crossing the roll axis. (FIG. 2A). And
The adhesive sheet 21 is, as shown in FIG.
1, stretchable plastic film 42 and silicon layer 43
Were laminated in that order to form a substrate 40, and an adhesive layer 44 was provided on the surface of a paper sheet 41. The base material 40 is made of the adhesive sheet 21
The direction of the eyes of the paper sheet 41 (papermaking advance direction) and the centrifugal direction of the film 42 are matched in a direction along the diagonal winding direction of the paper sheet 41, and the paper sheet 41 in a direction intersecting the diagonal winding direction.
And the film 42 were improved in tear resistance. Film 4
As 2, a stretchable polypropylene (OPP), nylon or the like can be adopted. The silicon layer 43 secures releasability between the pressure-sensitive adhesive sheets 21 that are layered.

According to this embodiment, the following operations are provided. When the long roll body 24 is cut by the cutter 30 at the stage of manufacturing the adhesive roll 20, the powder 32 is supplied to the blade surface of the cutter 30 and the cut end of the long roll body 24 cut by the cutter 30. Thereby, even if the pressure-sensitive adhesive layer 44 of the pressure-sensitive adhesive sheet 21 on the upper layer side of the long roll body 24 is pushed into the lower layer by the blade surface of the cutter 30, the pressure-sensitive adhesive layers 44 of the pressure-sensitive adhesive sheet 21 on the upper layer side and the lower layer side remain powdery. They do not adhere to each other due to the interposition of the body 32 (FIG. 5). For this reason, at the stage of using the pressure-sensitive adhesive roll 20, the pressure-sensitive adhesive sheet 21 on the surface layer does not adhere to the pressure-sensitive adhesive sheet 21 on the lower layer side, so that it is easily peeled off and hardly torn.

In the case where the powder 32 is present on the cut end face of the adhesive roll 20, the above-described ease of peeling at the use stage,
Breakage resistance can be ensured stably for a long time (Fig. 2).

In the obliquely wound pressure-sensitive adhesive roll 20 which can easily remove the surface pressure-sensitive adhesive sheet 21 one by one, a starting end 21B of another pressure-sensitive adhesive sheet 21A is present below the pressure-sensitive adhesive sheet 21 on the upper layer side and on the lower layer side. When the pressure-sensitive adhesive sheet 21 is peeled off, the pressure-sensitive adhesive sheet 21A on the lower layer side tends to be peeled off (FIG. 3B). However, according to the present invention,
Since the upper and lower pressure-sensitive adhesive sheets 21 and 21A do not adhere at the cut end surface, only the surface-side pressure-sensitive adhesive sheet 21 can be peeled off with the diagonally wound pressure-sensitive adhesive roll 20 (FIG. 3A).

The above-described operation is also achieved by applying the present invention to the pressure-sensitive adhesive roll 50 of FIG. 4 in which the pressure-sensitive adhesive sheet 51 is continuously wound endlessly and laminated. In FIG.
52 is a powder.

In the practice of the present invention, the powders 32, 52
In order to prevent wear of the cutters 30 and 30A, it is preferable that the friction resistance is small.

[0014]

As described above, according to the present invention, in a cleaning adhesive roll manufactured by cutting a long roll body with a cutter, the upper adhesive sheet and the lower adhesive sheet are adhered at the cut end surfaces. In the use stage, the pressure-sensitive adhesive sheet on the surface layer can be easily peeled off and hardly broken.
