Abstract

PURPOSE:To easily and accurately produce a large number of paper cylinders same or different in dimension by inserting a column in a cylinder and inserting one end part of paper in the cylinder from the slit part thereof to held the same between the cylinder and the column and rotating the cylinder to wind up the paper. CONSTITUTION:In the production of a paper cylinder 4, at first, a column 2 is inserted in a cylinder 1 and, next, one end part of paper 3 is inserted in one of a large number of the slit parts a, a formed to the cylinder 1 to be held between the cylinder 1 and the column 2. Continuously, the cylinder 1 is rotated while pressed by the hand to wind up the paper 3 and the remaining end part of the paper 3 is coated with an adhesive. The winding-up of the paper is further continued to complete a paper cylinder 4 around the cylinder 1 and the column 2. Thereafter, the column 2 is pulled out of the cylinder 1 and the paper cylinder 4 is pulled out of the cylinder 1. By this constitution, the paper cylinder 4 is easily and efficiently produced and a large number of paper cylinders same or different in dimension are accurately produced.

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a paper tube manufacturing tool for making a paper tube for paperwork.

[0002]

2. Description of the Related Art Conventionally, as a means for producing a paper cylinder from a sheet of paper on a desk or the like, the paper is rolled up with the fingers of the hand from the end of the paper, and the remaining end of the paper is glued. Glue and fix to form a paper tube, or wrap it around a cylindrical stick such as a pencil as much as possible while holding the end of the paper with your fingers etc. as the center stick, and in that state, remove the center stick from the paper cylinder. There is no method, so there is a method to loosen the wrapping, pull out the center rod, roll up the paper and attach an adhesive to the end of the remaining paper to fix it to form a paper cylinder.

[0003]

The problem to be solved by these methods is to make a number of paper cylinders having the same outer and inner diameters, which are necessary for delicate model making and workpieces by these methods. In addition, it is very time-consuming and very difficult to make a paper cylinder having a small outer diameter and a long size.

[0004]

In order to solve these problems, the present invention provides a paper tube manufacturing tool having the following construction. That is, a cylinder with a thickness close to the inner diameter of the cylinder is inserted into a cylinder that has several notches with gaps from one end to the vicinity of the other end, and the cylinder and the cylinder are connected through the notch of the cylinder. Insert the end of the paper into the space of the paper cylinder to wind it up, roll it up, apply adhesive to the end of the other remaining paper, and further wind it to fix the paper into a paper cylinder The paper is characterized in that by pulling out the cylinder from the paper, the cylinder can be easily pulled out from the paper cylinder made by being rolled up and glued and fixed, and one piece of paper is made into a paper cylinder. It is a tube making tool.

[0005]

With the paper tube manufacturing tool configured as described above, a paper tube can be easily made from a single sheet of paper, and if the paper has the same size, it has the same outer diameter and the same inner diameter. You can make a paper cylinder that holds. Also, by using paper tube manufacturing tools with different thicknesses and lengths, it is possible to easily and freely create many kinds of paper tubes with different thicknesses and lengths.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A paper tube manufacturing tool according to the present invention will be described in detail below with reference to the drawings showing the embodiments. FIG. 1 is a perspective view of the present invention, in which (1) shows notches (a) and (a ′).
(A ″) ..., A cylinder, and (2) is a cylinder having a thickness close to the inner diameter of the cylinder (1). As shown in FIG. With the cylinder (2) inserted in, the one end of the paper (3) is made into the paper cylinder (4) so that the cut-in portions (a) (a ') (a ") of the cylinder (1).・
.. Inserted into one of them, sandwiched between cylinder (1) and cylinder (2) and fixed, and while holding cylinder (1) by hand, roll up paper (3) to wind up, and the remaining end of paper (3) By attaching an adhesive to the portion and further winding it up, a paper cylinder (4) having the cylinder (1) and the cylinder (2) as the central axes as shown in FIG. 2 (B) is formed. As shown in FIG. 2 (C), by pulling out the cylinder (2) from the cylinder (1), the end of the cylinder (1) having the cutouts (a), (a ′), (a ″), ... Becomes a shape in which the tension as a cylinder against the tightening force generated by the paper (3) held by the cylinder (2) being held inside the cylinder (1) is collapsed. 4) Grasp with one hand and the other hand with the cylinder (1)
The cylinder (1) can be easily pulled out from the paper tube (4) by grasping the non-notched end portion and pulling it in both directions. From these things, it becomes possible to easily make a paper cylinder out of paper.

[0007]

As described above, according to the present invention, a paper tube can be created by inserting the paper into the paper tube manufacturing tool to form a paper tube and rolling it up, and changing the size of the paper. By doing so, the length and thickness of the paper cylinder can be freely changed. As a result, it can be used for making works using a wide range of paper cylinders from infants to the elderly, and is far better than the traditional handmade paper cylinder work. It has various effects such as making it possible to produce a wide variety of works.

Claims (1)

[Claims] 1. A cylinder having a thickness close to the inner diameter of the cylinder is inserted into a cylinder having a plurality of notches having a gap from one end to the vicinity of the other end, and the cylinder is inserted through the notch of the cylinder. Insert the end of the paper into the space between the column and the cylinder to wind it up, roll it up, attach the adhesive to the end of the other remaining paper, and then wind it up to fix the paper into a paper cylinder. By removing the cylinder from the cylinder, the cylinder can be easily pulled out from the paper cylinder that is rolled up and glued and fixed to make a piece of paper into a paper cylinder. A characteristic paper tube manufacturing tool.
