2. Description of the Related Art When spraying paint or wall material on a construction site or a renovation site, a curing sheet or masking tape is attached to the area around the sprayed area in advance so that paint or wall material can be applied to an extra place. It is normal to make sure that it does not stick out. This type of work will be outlined by taking the case of painting a wall surface with a window as an example. First, for example, a length of 1 m.
The curing sheet prepared in the state of being wound into a rod
The sheet is brought into contact with one side of the window, and plural portions of the sheet end are temporarily fixed around the window by using a piece of gum tape or the like. Next, the curing sheet is unwound along the window, and the curing sheet is cut with a cutter knife or the like at a portion corresponding to the other side portion of the window. Then, after depositing the rest of the curing sheet (rod-shaped one) in the vicinity of the workplace, the sheet end on the cut side is attached around the window with gum tape or the like.

When the window is large, the above work is repeated to cover the entire window with a curing sheet. After that, the entire circumference of the curing sheet is stitched with duct tape or the like along the contour of the window.

[0004]

As described above, this kind of work must be carried out while alternately taking out and cleaning up the curing sheet, cutter knife, gum tape, etc. prepared in the form of rods. It was very troublesome. In particular, it is not only troublesome but also difficult to perform work at a high place on a scaffold, so usually two or more people performed it.

The present invention has been made in view of the above circumstances, and makes it possible to easily and quickly take out a sheet material such as a curing sheet for a length as required, and to perform various curing operations. An object of the present invention is to provide a roll sheet capable of performing work with high efficiency, accuracy, and a small number of people, and a portable sheet feeding device using the roll sheet.

[0006]

According to the present invention, the following technical measures have been taken in order to achieve the above object. That is, in the present invention (roll sheet) according to claim 1, an adhesive band having an adhesive surface on one side is provided along one side of the sheet, and the other side of the sheet is bonded within a range not hiding the adhesive band. It is characterized in that it is folded toward the band and is wound along the longitudinal direction of the adhesive band.

With such a structure, since the sheet is folded, the roll shape as a whole becomes compact and easy to carry. Further, since the roll width is small, there is an advantage that it can be easily unwound. Of course, the sheet can be unfolded at the same time as it is unwound, and the sheet becomes wide so that there is no problem in use.

Moreover, since the sheet is provided with the adhesive band, there is an advantage that it is not necessary to carry a gum tape or the like and to cut out the tape. The roll features of the sheet are now retained by utilizing the sticky surface of the adhesive strip so that the roll features do not loosen during handling. The adhesive band is preferably formed so as to be thicker than the sheet thickness (claim 2).

By doing so, the rigidity of the adhesive band becomes strong, and the unwinding and handling of the sheet becomes easy. In addition, in order to thicken the adhesive band, a method of locally forming the base portion of the adhesive band in the sheet (a region to which the adhesive is applied) thicker than other sheet portions, or a method of forming the adhesive band Then, a method of attaching a single-sided tape or a double-sided tape to one side of the sheet can be adopted.

The method of using a single-sided tape or double-sided tape as the adhesive band has the advantages of facilitating the production of the adhesive band and reducing the cost. On the back surface of the adhesive band, it is possible to display a color for identifying the sheet material (claim 3). By doing this, as the sheet material, for example, those having different thicknesses or colors, or those having different materials themselves,
When you prepare various items, you can easily identify them. Therefore, there is no mistake in handling.

The present invention (portable sheet feeding device) according to claim 4 further comprises a holder portion for rotatably holding the roll sheet according to any one of claims 1 to 3.
It has a carrying attachment portion provided on the holder portion. With such a configuration, the roll sheet can be carried in a state of being released, so that the roll sheet is more convenient to carry and the sheet can be unwound more easily.

The carrying attachment portion is provided to allow the holder portion to be attached to a worker's waist, arm or the like, and various structures and shapes are conceivable.
It is convenient to provide the holder portion with a cutter that can cut the roll sheet when the sheet is unwound along the longitudinal direction of the adhesive band (claim 5).

In this way, it is not necessary to carry a cutter knife or the like separately, so that the work is facilitated and the roll sheet is easily cut.

Embodiments of the present invention will be described below with reference to the drawings. 1 to 3 show an embodiment of a roll sheet 1 according to the present invention, and FIGS. 6 to 8 show a portable sheet supply according to the present invention configured by using the roll sheet 1. 1 shows an embodiment of the device 2.

First, the roll sheet 1 will be described.
The roll sheet 1 is obtained by folding a sheet 3 having a predetermined width as shown in FIG. 2 into a plurality of folding lines (shown by chain double-dashed lines) parallel to each other, and then winding the sheet 3 along the longitudinal direction thereof. It is a thing. The sheet 3 is formed of a polyethylene or vinyl thin resin sheet, thin oil paper, non-woven fabric, or the like, and one side length when unfolded is about 1 m when used as a curing sheet or the like. An adhesive band 5 having an adhesive surface 4 on only one side is provided on one side (upper side in FIG. 2) of the sheet 3.

When the sheet 3 is folded, the side opposite to the adhesive strip 5 (downward in FIG. 2) is repeatedly folded inward when the adhesive surface 4 of the adhesive strip 5 is used as a reference. Is being done. And as a final fold,
The adhesive band 5 is not hidden, that is, the adhesive surface 4 is not covered with the sheet 3. In practice, the roll width A (see FIG. 1) is about 11.5 cm for convenience of carrying, and the folding width B in this case is 10 cm.
It was less than or equal to cm.

As is apparent from the above description, the winding direction of the sheet 3 is along the longitudinal direction of the adhesive band 5. It is preferable to use a hollow winding core 6 in the winding center portion. In this winding state, the back surface of the adhesive band 5 and the adhesive surface 4 are overlapped and bonded to each other, so that the roll shape does not become loose.

In the sheet 3, a backup layer 7 which is thicker than other sheet surface portions is formed at a corresponding portion where the adhesive band 5 is formed, and the backup layer 7 is adhered to one surface of the backup layer 7 as shown in FIG. It has a structure to apply the agent. As the adhesive, it is preferable to select one that can be attached and detached multiple times. Since the backup layer 7 strengthens the adhesive band 5, the sheet 3 is not only easy to unwind and handle, but also a folding space for the sheet 3 is secured between the adhesive bands 5 in a roll state. Therefore, there is an advantage that the roll shape can be formed into a straight cylindrical shape.

The adhesive band 5 has a structure in which a single-sided tape 8 is attached to one side of the sheet 3 as shown in FIG. 4, or a double-sided tape 9 is attached to one side of the sheet 3 as shown in FIG. It is possible to adopt a structure in which In these structures, the material thickness itself of the single-sided tape 8 or the double-sided tape 9 constitutes the backup layer 7. As described above, the sheet roll 1 configured in this manner has different thicknesses and colors as the material of the sheet 3, or different materials themselves (for example, those made of oil paper or non-woven fabric).
Etc. can be used for manufacturing. Therefore, the adhesive band 5 has a color display (for example, the entire adhesive band 5 is colored, a colored line is drawn, a symbol, a material name, etc. are specified on the back surface (the back surface side with respect to the adhesive surface 4) of the adhesive band 5. Repeatedly fill in along the longitudinal direction)
The roll sheet 1 can be easily identified.

Next, the sheet feeding device 2 will be described. The sheet feeding device 2 enables the worker to wear the roll sheet 1 via the waist belt 12 or the like as shown in FIG. 6, and as shown in FIGS. A box-shaped holder 13 that can store
It has a carrying attachment portion 14 that allows the holder portion 13 to be attached to the waist belt 12.

The holder portion 13 has a box body 17 and a lid body 18 which is provided with an upper opening capable of being opened and closed with respect to the box body 17. Inside the box body 17, the roll sheet 1 is provided. A shaft 20 that rotatably holds is erected.
A sheet outlet 21 for unwinding the sheet 3 from the roll sheet 1 is formed at one location on the peripheral wall of the box body 17. The sheet outlet 21 is opened laterally along one surface (upper surface in FIG. 8) of the peripheral wall of the box body 17, and a cutter 23 is attached to a corner portion of the peripheral wall which is the opening destination. ing.

A protective plate 24 is superposed on the cutter 23 from the outside thereof, and the protective plate 24 is a long hole 25 formed on the peripheral wall of the box body 17.
A slide piece 27 penetrating (see FIG. 7) holds the blade of the cutter 23 so that it can be moved forward and backward in a direction in which it can be exposed or hidden. This protective plate 24 is the box body 1
Due to the spring 28 provided inside 7, normally the cutter 23
It is designed to hide the cutting edge of.

That is, when the sheet 3 is unwound from the sheet outlet 21 and is strongly rubbed against the cutter 23, the protective plate 24 moves backward against the elastic force of the spring 28 and the cutter 23 moves. This allows the cutting of the sheet 3 as it exposes the cutting edge.
Further, after the sheet 3 is cut, the original state is restored by the spring 28, so that the blade edge of the cutter 23 is hidden and the hands or the like are not accidentally injured.

The sheet 3 on the roll sheet 1 side after cutting is bonded and held by the adhesive band 5 between the sheet outlet 21 and the cutter 23 on the peripheral wall of the box body 17, A step portion 29 is provided in this portion of the. Therefore, the non-contact space X for the adhesive band 5 of the sheet 3 is formed corresponding to the step 29. Therefore, when the sheet 3 is unrolled next, it is possible to easily insert a finger into the non-contact space X.

The carrying attachment portion 14 is the waist belt 1 of the worker.
It is formed as a lateral through-hole 32 through which 2 can be inserted. Thereby, the holder portion 13 can be attached to the worker. The carrying attachment portion 14 may be formed of a belt material 35 having button hooks 33 and 34, which are engageable with and disengageable from each other as shown in FIG. 9, at both ends thereof. That is, if one of the end portions of the belt material 35 is passed through the inside of the waist belt 12 and the button hooks 33 and 34 are coupled to each other,
A belt (comparable to the through hole 32 shown in FIG. 7) is formed by the belt material 35, and the holder portion 13 can be attached to the operator by this.

Although not shown, the waist belt 1 is directly attached to the box body 17 of the holder 13 without providing the lateral through holes 32 and the belt material 35 as described above.
The waist belt 12 can also be used as the carrying attachment portion 14 by attaching 2. In this case, instead of the waist belt 12, a velcro (not shown) wrapped around the arm may be used.

Further, as another mode of the carrying attachment portion 14, one of the surface fasteners (having a Velcro tape in a planar shape) is attached to a part of clothes worn by an operator, such as a cuff portion. Alternatively, it is also possible to adopt a structure in which the other surface fastener is attached to an appropriate place of the holder portion 13 and these are engaged with each other as needed.
That is, in this case, the carrying attachment portion 14 is configured by both surface fasteners.

On the other hand, the shape and structure of the holder portion 13 are not limited, and for example, as shown in FIG. 10, the roll sheet 1 may be held so that it is exposed more than half. In this case, in the direction orthogonal to the longitudinal direction of the adhesive band 5 with respect to the roll sheet 1,
The cut 38 is provided at a predetermined interval, and the cutter 2
It is preferable that the sheet 3 can be cut without the sheet 3 (see FIG. 8).

A portable sheet feeding device 2 having such a structure
In this case, the worker can move to the work place and work while the holder 13 is attached to the waist or the like, which eliminates the need to carry the roll sheet 1 one by one. Then, when the sheet 3 is used, the work of unwinding the sheet 3 from the holder portion 13 by a desired length and cutting it, and holding only the separated sheet 3 in a hand and adhering it to a predetermined place can be performed exclusively. That is, it is not necessary to deposit the remaining roll sheet 1 somewhere and then to pick up the separated sheet 3 again to carry out the pasting work.

The present invention is not limited to the above embodiment. For example, in the roll sheet 1, the number of times the sheet 3 is folded, the folding width, the size when unfolded, and the like are not limited at all. Of course, the width and thickness of the adhesive band 5 and the roll diameter are not limited.
