It is well known that the material is wound onto a take-up roll. Typically, guide rollers consist of hollow cylindrical rollers and are quite elongated. Its diameter is 30-50 cm, and its length reaches 4-10 m. Further, in the winding position, the presser roller is in contact with the web material and its contact pressure acts on the web material, so that the web material is tightly wound. The presser roller also consists of a hollow cylindrical roller and is extremely elongated.

る。 By the way, this kind of web material guide roller,
Elongated rollers, such as web material presser rollers, have traditionally had problems associated with their stiffness and weight. In order to smoothly accelerate and decelerate each roller when rotating at high speed, it is preferable to reduce the weight of the entire roller and reduce its inertial mass. In reducing the weight of an elongated cylindrical roller, the thickness of the peripheral wall of the roller has the greatest influence. Therefore, it is preferable to make the peripheral wall of the roller thin. however,
In the case of an elongated roller, the roller is likely to be bent due to its own weight, and rotational wobbling of the roller is likely to occur.
Roller twisting is also likely to occur. Therefore, it is necessary to maintain the strength and rigidity of the roller. When the peripheral wall of the roller is made thinner, the strength of the roller is inevitably reduced, and its rigidity is inevitably lowered. Therefore, there was a problem in that the peripheral wall of the roller could not be made thinner, which limited the ability to reduce the weight of the roller.

ている。したがつて、補強材２の頂陵３がローラ
１の内周面に内接しているものである。 In FIG. 1, this roller consists of a hollow cylindrical roller 1 and has a rectangular cylindrical reinforcing member 2 of a certain length. As shown in FIG. 3, the reinforcing member 2 has an equilateral triangular cross section and has three ridges 3, which are large enough to inscribe the inner peripheral surface of the roller 1. and,
This reinforcing material 2 is press-fitted and inserted into the roller 1. Therefore, the top ridge 3 of the reinforcing material 2 is inscribed in the inner peripheral surface of the roller 1.
さらに、第２図に示すように、補強材２の頂陵

The reinforcing material 2 and the inner part of the roller 1 are welded together by plug welding 4. The plug welds 4 are alternately applied along the top ridge 3 of the reinforcing material 2 in a staggered manner. Alternatively, each plug weld 4 may be applied at the same longitudinal position and in parallel.
さらに、このローラは一対のジヤーナル５を有

それはない。さらに、ねじれに対する剛性も高
く、ローラのねじれが生じるおそれもない。 Therefore, in the case of this roller, a triangular truss is formed by the roller 1 and the reinforcing member 2, and its strength and rigidity are high. Therefore, even if the roller is elongated, there is no risk of the roller being bent due to its own weight, and there is no risk of rotational wobbling of the roller. Furthermore, the rigidity against torsion is high, and there is no possibility that the roller will twist.
さらに、円筒状ローラ１の周壁を薄くすること

る。 Furthermore, it is also possible to make the peripheral wall of the cylindrical roller 1 thinner. Even if the peripheral wall of the roller 1 is made thin, its rigidity is maintained and no bending or twisting occurs.
Therefore, the weight of the entire roller can be reduced, and its inertial mass can be reduced. Therefore, when rotating the long and thin roller at high speed,
This can be smoothly accelerated and decelerated.

い。 Note that the square tubular reinforcing material 2 of this roller does not necessarily have to have a triangular cross section. As shown in FIG. 5, a rectangular cylindrical reinforcing material 7 with a square cross section may be used, inserted into the cylindrical roller 1, and its top ridge 8 inscribed in the inner peripheral surface of the roller 1. good. Then, when the inner part of the reinforcing material 7 and the roller 1 are welded by plug welding 9, the inner part of the roller 1 is welded.
and the reinforcing material 7 form a composite truss,
Its strength can be increased and its rigidity can be improved, and similar effects can be obtained. Rectangular cylindrical reinforcing materials with other polygonal cross sections may also be used.

接されているのは第１図のローラと同様である。 FIG. 6 shows another embodiment. This roller consists of a plurality of cylindrical rollers 10. As shown in FIG. 9, the roller 10 is made by bending a metal plate such as a steel plate, curving it, and performing groove welding 11 thereon. A plurality of disc-shaped ribs 12 are arranged between each roller 10. Further, as shown in FIG. 7, the rollers 10 and the ribs 12 are welded by plug welding 13, and the rollers 10 and the ribs 12 are welded by groove welding 14. . Then, a plurality of rectangular cylindrical reinforcing materials 1
5 is press-fitted into the roller 10, and the top ridge of the reinforcing material 15 is inscribed in the inner peripheral surface of the roller 10. Similar to the roller shown in FIG. 1, the reinforcing member 15 and the inner part of the roller 10 are welded by plug welding.

ることができる。 Therefore, the entire roller is reinforced by each reinforcing member 15 and each rib 12, and its strength and rigidity are high. Therefore, no deflection or twisting of the rollers occurs. It is also possible to make the peripheral wall of the roller 10 thinner, thereby reducing the weight of the entire roller. Furthermore, in the case of this roller, a plurality of rollers 10 can be formed by bending and curving a metal plate, and there is no need to integrally mold an elongated roller. Therefore, the manufacturing cost can be reduced.
