Description

  The present invention relates to a masking material in which an adhesive surface portion is provided along a longitudinal direction of a sheet on a part of the masking sheet in the sheet width direction and a method for manufacturing the same.

  The masking material is displayed so that, for example, paint mist does not adhere to the non-coating object at the painting site, so that the non-coating object is covered with a sheet, and the display and storage items are not covered with dust. It can be used to cover objects and stored items with a sheet. Conventionally, an adhesive surface for fixing is attached to one end side in the sheet width direction of the masking sheet so that the masking sheet can be fixed to an object to be masked. It is provided along the direction (see, for example, Patent Document 1).

Japanese Patent Laid-Open No. 7-303851

For this reason, when the masking target is one side of the outer surface of the article such as a wall surface, one end side in the sheet width direction is adhesively fixed to the upper part of the masking target or the like with the adhesive surface portion provided on the one end side, If the masking sheet is hung by its own weight like a curtain, the masking target can be covered with a single masking sheet with good workability, but the masking target is the outer surface of an article such as an automobile, When it is necessary to cover the outer surface of an article so as to be wrapped with a masking sheet, there is a drawback that it is difficult to cover with a single masking sheet with good workability.
In other words, since the conventional masking material has an adhesive surface portion on one end side in the sheet width direction, when covering the outer surface of an article such as an automobile installed on the floor surface so as to be wrapped with a single masking sheet, the masking sheet In order to prevent deviation, at the lower part of the one side of the outer surface of the article, one end side in the sheet width direction is adhesively fixed along the vicinity of the floor surface with the adhesive surface portion, and then the masking sheet is expanded toward the other side, Although it is necessary to wrap the outer surface, the masking sheet hangs down and comes into contact with the floor surface when the masking sheet is adhesively fixed along the floor surface near the floor or when the masking sheet is spread toward the other side. It is easy to wrap the outer surface of the article with a masking sheet that is soiled due to contact with the floor surface. On the other hand, the outer surface of the article may be soiled. While held so as not to contact the floor surface side and it is or of adhesive along near the floor in the masking sheet adhesive surface, must be expanded toward the masking sheet on the other side surface side occurs.
The present invention has been made in view of the above circumstances, and even if the masking target is the outer surface of an article such as an automobile and the article outer surface needs to be covered with a masking sheet, it is one sheet. It is intended to be able to cover with good workability with this masking sheet.

  A first characteristic configuration of the present invention is a masking material in which a pressure-sensitive adhesive surface portion is provided along a longitudinal direction of a sheet in a portion of the masking sheet in the sheet width direction, and an intermediate sheet portion in the middle of the sheet width direction in the masking sheet Each of the left and right side sheet parts sandwiched is folded in series along the longitudinal direction of the sheet so as to overlap each other on the same side surface side of the intermediate sheet part, and the adhesive sheet is attached to the other side surface of the intermediate sheet part. The surface portion is provided.

[Action and effect]
In order to prevent the masking sheet from shifting, the other side of the intermediate sheet in the sheet width direction of the masking sheet is fixed to the upper part of the outer surface of the article when the adhesive surface is adhesively fixed along the longitudinal direction of the sheet. The side sheet parts on both the left and right sides folded so as to overlap the intermediate sheet part can be held so as not to contact the floor surface side, and at this time, the side sheet part hangs down to the floor surface side. Even if it comes into contact, the side sheet portion hangs down while covering the outer surface of the article, so there is no possibility of soiling the outer surface of the article.
In addition, for example, the left and right side sheet portions sandwiching the intermediate sheet portion, one side sheet portion overlaps one side surface side of the intermediate sheet portion, and the other side sheet portion is the other side surface of the intermediate sheet portion. When it is folded in series along the longitudinal direction of the sheet so that it overlaps the side and an adhesive surface is provided on either side of the intermediate sheet, the intermediate sheet is adhesively fixed to the outer surface of the article. Since one of the side sheet parts folded so as to overlap the side where the adhesive surface part of the sheet part is provided is held so as to be sandwiched between the intermediate sheet part and the outer surface of the article, the side sheet thereof There is a drawback that it is difficult to grasp the end of the part and difficult to spread.
However, the masking material according to the present invention folds the side sheet portions on both the left and right sides sandwiching the intermediate sheet portion in series along the longitudinal direction of the sheet so as to overlap each other on the same side surface side of the intermediate sheet portion. When the intermediate sheet part is adhesively fixed to the outer surface of the article, the folded side sheet parts on both the left and right sides are not sandwiched between the intermediate sheet part and the outer surface of the article. Since the adhesive surface is provided on the other side of the intermediate sheet so as to be held on the upper side of the fixed intermediate sheet, either side of the left and right sides of the intermediate sheet is adhesively fixed to the outer surface of the article. The end portion of the sheet portion can be easily grasped and easily spread on both the left and right sides, and the outer surface of the article can be covered with a masking sheet.
Therefore, even when the masking target is the outer surface of an article such as an automobile and it is necessary to cover the outer surface of the article with a masking sheet, the masking sheet can be covered with a single masking sheet with good workability.

  According to a second characteristic configuration of the present invention, the intermediate sheet portion is divided into left and right in the sheet width direction, and two folded sheet members are formed by the divided intermediate sheet portions and the side sheet portions on the left and right sides respectively. The adhesive tape is adhered and integrated over both of the divided intermediate sheet portions of the two folded sheet members, and the adhesive tape is formed through a gap between the pair of divided intermediate sheet portions. The adhesive surface portion is formed with the adhesive surface facing outward.

[Action and effect]
Without applying the adhesive material to the intermediate sheet portion, the adhesive surface portion can be simply provided on the other side of the intermediate sheet portion using the adhesive tape.

  The third feature of the present invention is that the intermediate sheet portion and the side sheet portion of the masking sheet are each formed of a series of sheet members over the entire width, and an adhesive layer is provided on the other side surface of the intermediate sheet portion. And it exists in the point which comprises the said adhesion surface part.

[Action and effect]
The adhesive surface portion can be provided at any position in the sheet width direction on the other side surface of the intermediate sheet portion without particularly performing processing such as separating the intermediate sheet portion left and right in the sheet width direction.

  According to a fourth characteristic configuration of the present invention, the width of the sheet portions facing each other with the adhesive face portion interposed therebetween is formed such that the width of one sheet portion is narrower than the width of the other sheet portion.

[Action and effect]
In the masking material in which the width of the sheet parts facing each other across the adhesive surface part is the same width, the intermediate sheet part is adhesively fixed with the adhesive surface part along the center in the width direction of the outer surface of the article to be masked. Although the outer surface of the article can be covered almost uniformly over the entire width, the masking target is a large article that is long and wide, such as an automobile, is high in height, and is difficult to reach the upper center of the article in the width direction. In the case of the outer surface, there is a problem that it is difficult to adhere and fix along the upper central part in the width direction of the article outer surface, and it is difficult to cover the article outer surface substantially uniformly over the entire width.
As opposed to the above, according to the fourth feature configuration, the width of the sheet portion opposed across the adhesive surface portion is formed such that the width of one sheet portion is narrower than the width of the other sheet portion. The intermediate sheet portion is biased to either the left or right in the width direction of the outer surface of the article to be masked so that the narrow one sheet portion is closer to the left or right in the width direction of the outer surface of the article than the other wide sheet portion. By adhering and fixing along the upper portion with the adhesive surface portion, the outer surface of the large article whose masking target is difficult to reach the central upper part in the width direction can be covered almost uniformly over the entire width.

  A fifth characteristic configuration of the present invention is that the sheet is wound around an axis along the sheet width direction so as to be freely drawn out.

[Action and effect]
Since it is wound around the axis along the sheet width direction so that it can be fed out freely, when storing and transporting the masking material, the folding position of the side sheet part folded in series along the sheet longitudinal direction is It is easy to handle so that it does not collapse, and when the masking sheet is adhesively fixed at the adhesive surface portion, it can be adhesively fixed with good workability while rolling the masking material to rewind.

  According to a sixth feature of the present invention, the masking material according to claim 2 is manufactured by using a sheet raw material obtained by winding a folded sheet material obtained by folding a cylindrical sheet material flatly along the longitudinal direction of the cylinder. The folded sheet material fed out from the original sheet is folded back in series along the longitudinal direction of the sheet, and the exposed sheet portion folded back over the outermost side in the sheet overlapping direction is taken from the folded portion. The exposed sheet portion including the folded portion is formed in the divided intermediate sheet portion by cutting in series along the sheet longitudinal direction at a distant location, and the remaining sheet portion overlapping the divided intermediate sheet portion Is formed on the side sheet portion to create the folded sheet member, and the folded sheet member is wound to form a folded sheet roll. Using the two of the folded sheet rolls, the folded sheet members, the side sheet portions facing each other in the sheet width direction, and the sheet of the divided intermediate sheet portion The sheet overlap direction is such that the edges along the longitudinal direction face each other with a gap therebetween, and the adhesive surface faces the outside of the sheet overlap direction from the gap across both of the divided intermediate sheet portions. A second step of creating a masking material wound body by adhering an adhesive tape from the inside of the sheet, creating a masking material provided with the adhesive surface portion, and winding the masking material freely around an axis along the sheet width direction. It is in the point equipped with.

[Action and effect]
In the first step, the folded sheet material that is folded flat along the longitudinal direction of the cylinder fed from the original sheet is folded back in series along the longitudinal direction of the sheet, and folded over the outermost side in the sheet overlapping direction. The exposed sheet portion is cut in series along the longitudinal direction of the sheet at locations away from the folded portion, thereby forming the exposed sheet portion including the folded portion in the divided intermediate sheet portion, and the divided intermediate sheet portion. The remaining sheet portion that overlaps is formed on the side sheet portion to create a folded sheet member, and the folded sheet member is wound to create a folded sheet roll.
In the second step, two folded sheet rolls are used, and the folded sheet members are arranged so that the side sheet portions face each other in the sheet width direction and in the sheet longitudinal direction of the divided intermediate sheet portion. Adhering from the inside in the sheet overlap direction so that the edges along the line are opposed to each other with a gap, and the adhesive surface faces the outside in the sheet overlap direction from the gap across both of the divided intermediate sheet portions A masking material having an adhesive surface portion is prepared by adhering the tape, and the masking material is wound around the axis along the sheet width direction so that the masking material can be unwound.
Therefore, even when the masking target is the outer surface of an article such as an automobile and it is necessary to cover the outer surface of the article with a masking sheet, the wide width that can be covered with a single masking sheet with good workability. A masking material can be manufactured using the sheet | seat original fabric and adhesive tape which are folded up and rolled up the cylindrical sheet raw material along the cylinder longitudinal direction.
