Abstract

PROBLEM TO BE SOLVED: To omit the wrapping of machine grazed paper with a protective paper by providing a part of the machine grazed paper with the same function as the protective paper. SOLUTION: This machine grazed paper 10 has an excess length in comparison with a longitudinal length L defined by the standard, by an outer peripheral length x of the machine grazed paper, and the excess part 12 is used as a protective member, which omits the wrapping of the machine grazed paper 10 with the protective paper as done for the conventional machine grazed paper, and reduces the manufacturing cost.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a roll paper used for a large area printing process.

[0002]

2. Description of the Related Art As a large-sized printer used for large-area printing of posters, artworks, etc., it is desirable to use a recording method such as an ink jet recording method, a thermal transfer recording method, or a pressure-sensitive recording method for large-size roll paper. For printing images, characters, and the like. Conventionally, when roll paper is placed in a distribution process, its outer periphery is wrapped with protective paper. This protective paper is for protecting the roll paper from damage such as dirt.

[0003]

However, when the roll paper is wrapped by using the protective paper, there is a problem that the wrapping is troublesome and the cost of the roll paper is increased.

Further, when the roll paper is wrapped with protective paper without fixing the winding end of the roll paper with an adhesive tape or the like, if the rigidity (warpage strength) of the roll paper is strong, the protective paper is removed. There was a problem that the roll paper was unraveled immediately and could not be set in an information device such as a printer, a facsimile or a copying machine.

Accordingly, an object of the present invention is to provide a roll paper having a function equivalent to that of protective paper, thereby omitting packaging with protective paper.

[0006]

SUMMARY OF THE INVENTION In order to solve the above-mentioned problems, the present invention takes an extra length of the outer periphery of the roll paper longer than the length in the longitudinal direction specified by the standard, and uses the extra portion as a protective member. Use as In the present specification, the protection member refers to a member that performs the same function as the protection paper, and an extra portion in the longitudinal direction of the roll paper functions as a protection member. According to the roll paper of the present invention, it is not necessary to wrap the roll paper with protective paper as in the related art, and the manufacturing cost of the roll paper can be reduced.

[0007]

Embodiments of the present invention will be described below with reference to the drawings.

FIG. 1 is a plan view of a roll paper 10 of the present invention. The roll paper 10 is a long, large-area printing paper, and the lengths in the longitudinal direction and the lateral direction thereof are determined in advance by standards. In FIG. 1, reference numeral 11 denotes a print effective area of the roll paper 10, and a length L in the longitudinal direction is a length determined in advance by a standard. Reference numeral 12 denotes an extra portion taken in the longitudinal direction of the roll 10, and the length x in the longitudinal direction corresponds to the length of the outer periphery of the roll paper 10. For example, when the diameter when the roll paper 10 is wound in a roll shape is d, the value of x is a value determined by π × d.

FIG. 2 shows a state in which the roll paper 10 is wound around the outer periphery of the paper tube 20 in a roll shape, and the end of the winding is adhered and fixed with a removable adhesive tape 40. Since the length of the roll paper 10 in the longitudinal direction is longer than the original length determined by the standard by the outer peripheral length of the roll paper 10, the excess portion 12 functions as a protective member and is wound into a roll. The outer periphery of the rolled paper 10 can be protected.

With this configuration, the roll paper can be set in an information device such as a printer, a facsimile, a copying machine or the like while protecting the roll paper without using the protection paper. Further, conventionally, there was a problem that the roll paper was unraveled when the protective paper was removed, but according to the present embodiment, such a problem does not occur.

As shown in FIG. 3, the removable adhesive tape 3
Reference numeral 0 denotes a base paper 31 and a release paper 32. The base paper 31 is made of paper, film, metal foil, and the like.
A handle part 33 and an adhesive part 34 are provided. As the release paper 32, a high-density base paper such as glassine paper, clay-coated paper, polyethylene laminate base paper or the like coated with a release agent such as a silicone compound or a fluorine compound is used. And various types of pressure-sensitive adhesives of emulsion type, solvent type or solventless type such as vinyl ether type.

Since the adhesive is not applied to the back surface of the handle portion 33 and the adhesive is not stuck on the surface to be adhered (rolled paper), the user grips the handle portion 33 and rolls the removable adhesive tape 30. It can be peeled from the paper 10. As shown in FIG. 4, by aligning the direction in which the removable tape 30 is peeled off with the winding direction of the roll paper 10, the end of the roll paper 10 is removed when the removable tape 30 is peeled. Damage can be prevented. For this reason, it is possible to prevent the occurrence of troubles in the printing process due to damage to the wound end surface of the roll paper 10 and the like.

In the above description, the roll paper 10
Although the length x of the portion 12 extra in the longitudinal direction is set to the outer peripheral length of the roll paper 10, it may be slightly longer than the outer peripheral length.

The basis weight and thickness of the roll paper are not particularly limited, but a roll paper having high rigidity, for example,
Basis weight 190 g / m ^{2 to} 230 g / m ² , thickness 0.3 mm
In the case of using a roll paper having a thickness of up to 0.4 mm, there has conventionally been a problem that the roll paper can be unraveled when the protective paper is removed. However, in the present invention, there is no such a problem. The degree of freedom can be increased.

[0015]

According to the present invention, the extra length of the roll paper is more than the length in the longitudinal direction specified by the standard,
Since the extra roll paper is used as a protective member, it is not necessary to wrap the roll paper with the protective paper as in the related art, and the production cost of the roll paper can be reduced.
