で手作業に頼らざるを得ない状況にある。 Conventionally, for example, in the manufacturing process of FRP laminated shafts and rubber hoses, the circumference of a cylindrical mandrel was
When winding FRP prepreg or unvulcanized rubber strips in a spiral shape, the method used was to supply these strip materials directly onto the surface of a cylindrical mandrel. Therefore, (1) At the start of winding, as shown in FIG. 1, the tip of the strip material 1, that is, the cut edge 1a, which has been cut diagonally at a required angle as shown in FIG.
It must be pasted around the end 2a of the cylindrical mandrel 2 over the entire circumference with the cut edge 1a and the periphery of the end 2a aligned. However, it is extremely difficult to affix the cut edge 1a of the strip material 1 to the end 2a of the cylindrical mandrel 2 over the entire circumference at a predetermined position and angle with high accuracy. As a result, not only does the winding angle and pitch become irregular, leading to a deterioration in the quality of the actual product, but it is extremely difficult to automate the work of attaching the tip of the strip material at the start of winding, and it must be done manually. There is no situation.
(2) また巻付途中において、円筒マンドレルへの
帯状材料の巻付張力は、帯状材料の巻出張力に

う。(4) Furthermore, when performing multilayer winding as described above, the diameter of the intersection of right-handed and left-handed windings becomes larger than other parts, resulting in unevenness on the surface.
等の問題があるのが現状である。The current situation is that there are problems such as these.
本発明は上述した各問題点を解消すべく検討の

することにある。 Therefore, an object of the present invention is to attach the cut edge of a strip material in advance to a transfer roll having a diameter larger than that of the cylindrical mandrel, and then rotate this transfer roll so that the cylindrical mandrel pressed against the transfer roll is affixed on the transfer roll. An object of the present invention is to provide a method for winding a belt-shaped material having excellent flexibility, which allows the belt-shaped material to be accurately and extremely easily wrapped at a predetermined angle at a predetermined position on a cylindrical mandrel by transferring the belt-shaped material. .

のである。 That is, in the present invention, when winding a flexible band-shaped material in a spiral shape around the circumferential surface of a cylindrical mandrel, the cut edge of the band-shaped material cut obliquely at a predetermined angle is rotated at a diameter larger than that of the cylindrical mandrel. After pasting along a circumferential line perpendicular to the axial direction of the transfer roll, the transfer roll is further rotated to once spirally paste the strip-like material on the circumferential surface of the transfer roll at a desired angle.

する。 When winding the strip material 1 in a spiral shape on the cylindrical mandrel 2 at the winding angle A, material waste and product waste are minimized, and the cut edge 1a of the strip material 1 is wrapped around the transfer roll 3 at the beginning of winding. In order to facilitate the above alignment, it is necessary to cut the tip of the strip material 1 at a predetermined angle as shown in FIG. The following relationship holds between the diameter D of the cylindrical mandrel 2, the width W of the strip-shaped material, the winding angle A of the strip-shaped material, and the angle B of the cutting edge 1a at the tip: Strip-shaped material width (W) = Cylindrical mandrel Diameter (D) x π x cosA (wrapping angle) ...... (1) Tip angle (B) = 90° - wrapping angle (A) ...... (2) However, the above band material width (W) calculation Equation (1) is for a single butt spiral, and 2 for a double winding.
In the case of double or triple winding, the width of the material is three times as large, or in the case of n-fold winding, the width of the material is n times as large. However, the method according to the present invention is of course not limited to butt spirals, and can also be used in the case of multiple windings. However, the following description describes the procedure for the case of a butt spiral.

あるが、勿論これに限定されるものではない。 That is, a cut edge 1a having a length equal to the circumferential length of the cylindrical mandrel 2 is obtained. Thereafter, in FIG. 4, the material 1 whose tip has been cut is placed on the unwinding stand 5.
Set to 5. By changing the mounting angle of this unwinding stand 55, a predetermined winding angle A can be obtained. The tip of the material 1 is pulled out from the unwinding stand 55 set at a predetermined angle, and the cut edge 1a is placed at a predetermined position on the transfer roll 3 having a diameter at least three times that of the cylindrical mandrel 2. Set on the circumferential line of the transfer roll perpendicular to the axial direction. If, for example, a transfer roll 3 having a diameter six times the diameter D of the cylindrical mandrel 2 is used, the cutting edge 1a of the material 1 can be set by just crossing over the transfer roll at 60 degrees. Note that as means for setting the cut edge 1a of the material 1 on the transfer roll 3, there is a means (not shown) for vacuum suctioning the material from the inside of the transfer roll 3, but the present invention is of course not limited to this.

つく。 After the cutting edge 1a has been set on the transfer roll 3, the cylinder 24 is operated to bring the cylindrical mandrel 2 into contact with the transfer roll 3, and the drive motor 34 of the transfer roll 3 and the drive motor for traversing the strip material supply device 50 are activated. Start up 57. This causes the band-shaped material 1 to be wound around the cylindrical mandrel 2. To explain this operation in more detail, the transfer roll 3 is rotated by starting the drive motor 34 for the transfer roll 3. Further, since the cylindrical mandrel 2 pressed against the transfer roll 3 by the cylinder 24 is rotatably attached via a bearing, it starts rotating at the same time due to the frictional force with the transfer roll 3. Due to the rotation of the transfer roll 3, the cut edge 1a of the strip material 1, which has been transferred to the contact line between the transfer roll 3 and the cylindrical mandrel 2, leaves the transfer roll 3 and wraps around the cylindrical mandrel 2.

ものではない。 The means to ensure the transfer, that is, the transfer, is to use a cylindrical mandrel 2 and a transfer roll 3.
Examples include, but are not limited to, making a difference in the mold releasability of each surface of the transfer roller, or blowing air (not shown) from the inside of the transfer roll 3 toward the cylindrical mandrel 2 at the transfer position. It's not a thing.

34或いは57が制御される。 Next, regarding the lateral movement of the unwinding stand 55, the screw rod 56a is rotated by starting the lateral movement drive motor 57, and the movable body 53 starts lateral movement. Since the screw rod 56a and the guide bar 52 are attached parallel to the axis of the transfer roll 3, the unwinding stand 55 moves laterally in parallel to the transfer roll 3. Further, the motor 34 or 57 is controlled so that the following relationship always holds between the rotational distance X of the transfer roll 3 and the lateral movement distance Y of the unwinding stand 55.

ことができる。 Y=XcotA As described above, in the present invention, a cylindrical mandrel is rotatably brought into contact with the surface of a transfer roll which has a larger diameter than a cylindrical mandrel and is rotatable along its axis, and is first cut diagonally at a required angle. The cut edge of the strip material is pasted along the circumferential line of the roll perpendicular to the axial direction of the transfer roll, and then the transfer roll is rotated to apply the strip material to the surface of the transfer roll. Since the belt-like material on the transfer roll is pasted spirally at a predetermined angle and is automatically transferred onto the circumferential surface of the cylindrical mandrel, the following effects are achieved.
In other words, the cut edge of the strip material can be pasted on the transfer roll at the start of winding, and this work is extremely easy compared to pasting the entire circumference of a conventional cylindrical mandrel.
Not only can workability be greatly improved, but it also becomes possible to accurately and reliably attach the tape at a predetermined position and angle, and it is possible to eliminate irregularities in the winding angle and pitch.
