[0010]
[Action]
[Method of Claim 1]
The extension member supports a cylindrical body having a desired length. Since the round bar is parallel to the diagonal line of the rectangular paper piece, each piece of paper is always wrapped around the round bar in a cylindrical shape at a constant angle, and both ends of each cylindrical body are in the remaining center. The wall thickness is smaller than the part. Therefore, when the end of another cylindrical body is overlapped and wound around each thin end of each cylindrical body, the cylindrical body is continuously formed to a desired length while maintaining substantially the same outer diameter. Is done. The cylindrical body is formed in a continuous state from the beginning, and does not connect the cylindrical bodies formed in advance separately. The cylindrical body is sequentially fed in the direction of the extension member, but the extension member supports the cylindrical body in a penetrating state and prevents the cylindrical body from being bent.
[0011]
As shown in FIG. 1, when the corresponding end of the next cylindrical body is overlapped with one end of one cylindrical body, the one cylindrical body side of the rectangular paper piece that forms the next cylindrical body Of the two corners a and b, the corner a that is not on the diagonal line d parallel to the round bar coincides with the tip e at one end of the one cylindrical body. That is, a line f passing through the corner a and perpendicular to the round bar passes through the tip e at one end of the one cylindrical body. Let the intersection of the line f and the edge of the rectangular paper piece be c, and let the intersection of the line g passing through the corner b and perpendicular to the round bar and the round bar be h. In addition, for the corners, points, and lines corresponding to these corners a, b, points c, and lines f and g on the opposite side of the rectangular paper piece, the corners a, b, points c, and lines f, g The same reference numerals as in FIG. The thickness of the cylindrical body part formed by winding a triangular part formed by line segments connecting the corner part a, the corner part b, and the point c in the rectangular paper piece around the round bar is the corner part a, the point c, Gradually decreases from line f passing through to line g. On the other hand, the portion i between the intersection h and the tip e of the line g and the round bar in the cylindrical body already wound around the round bar is the corner a ′, corner b ′ and point c in the rectangular paper piece. 'Corresponds to the triangular portion formed by the line segments connecting to each other, and conversely decreases gradually from the line g (point h) to the line f (tip e). In addition, a cylindrical body part (part j) is formed by winding a parallelogram part formed by a line segment connecting a corner part a, a point c, a corner part a ′, and a point c ′ in a rectangular paper piece. Corresponding) thickness is constant. Therefore, when the corresponding end portion of the next cylindrical body is overlapped with one end portion of one cylindrical body, the corner portion a of the rectangular paper sheet forming the next cylindrical body is changed to the one cylindrical body. Since the corresponding end portions of the two cylindrical bodies are in a relationship in which the thicknesses are reduced in the opposite directions when matched with the tip e at the one end portion, the corresponding ends of the two cylindrical bodies. The portions complement each other in thickness, and are the same as the thickness of the cylindrical body portion j formed by winding the parallelogram portion around a round bar. That is, the continuously formed cylindrical body has the same thickness over the entire length. In other words, the cylindrical body continuously formed to have a desired length has the same outer diameter and the same inner diameter over the entire length.
[0012]
The operator simply places a rectangular paper piece on the sample paper piece and places it on a transparent plate, and rolls the round bar around the round bar in one direction along the guide line. What is necessary is just to wind in a cylindrical shape. Further, when the cylindrical body wound around the round bar is fed in the direction of the extension member, the tip of the cylindrical body is simply positioned on the one guide line where the corner portion of the sample paper piece is located. . Thus, the requirements of the above method are automatically satisfied. The substrate is used by being placed on a table or the like, but since the substrate is provided with anti-slip means on the lower surface, there is no possibility that the substrate will slip. Further, the substrate prevents the table or the like from being stained with glue or the like.

【The invention's effect】
[Method of Claim 1]
According to the method of claim 1, a cylindrical body having a desired length can be easily formed.
Since the extension member reliably supports the cylindrical body, even when the extension member is long, the work of rolling the round bar is easy. Since the round bar is parallel to the diagonal line of the rectangular paper piece, each piece of paper is always wrapped around the round bar in a cylindrical shape at a constant angle, and both ends of each cylindrical body are in the remaining center. The wall thickness is smaller than the part. Therefore, when the end of another cylindrical body is overlapped and wound around each thin end of each cylindrical body, the cylindrical body is continuously formed to a desired length while maintaining substantially the same outer diameter.

Create artisan placed on the transparent plate by simply aligning the sample for paper a rectangular piece of paper, the said paper strip by rolling in one direction along the rod to the guiding line around the round rod What is necessary is just to wind in a cylindrical shape. Further, when the cylindrical body wound around the round bar is fed in the direction of the extension member, the tip of the cylindrical body is simply positioned on the one guide line where the corner portion of the sample paper piece is located. . As described above, since the requirements of the above method are automatically satisfied, the operation becomes extremely easy. The substrate is used by being placed on a table or the like, but since the substrate is provided with anti-slip means on the lower surface, there is no possibility that the substrate will slip. Further, the substrate prevents the table or the like from being stained with glue or the like.
