[Means for Solving the Problems] In order to achieve the above object, the supporting device of the present invention is configured such that a long material to be continuously conveyed in a substantially horizontal direction is erected in a state where the long material is erected and mutually held on the same plane. A pair of rollers rotating in opposite directions, each pair of rollers of which rotation direction is obliquely upward with respect to the transport direction of the long material,
A stopper roller is provided for contacting an upper end edge of the long material that conveys near the pair of rollers.

In the support device of the present invention, it is preferable that the peripheral surfaces of the pair of rollers have a structure covered with an elastic body.

[Operation] In the support device of the present invention, a pair of rollers that rotate a long material that is continuously conveyed in a substantially horizontal direction in opposite directions on the same plane, each of which rotates in a direction in which the long material is conveyed. It is sandwiched between a pair of rollers facing obliquely upward with respect to the direction. At the same time, the stopper roller is brought into contact with the upper edge of the long material transported near the pair of rollers. Then, the long material is pulled between the pair of rollers in the transport direction of the long material.

Then, as the long material moves in the transport direction between the pair of rollers, the frictional force acts between the inner peripheral surfaces of the pair of rollers and the surface of the long material pressed against the long material. A traction force is applied to the inner peripheral surfaces of the pair of rollers from the length member in the transport direction of the long member. Then, the pair of rollers rotate with respect to each other in the outward direction. In other words, the pair of rollers rotate in opposite directions to each other in a direction in which the long material sandwiched therebetween is sent out from between the pair of rollers in the conveying direction of the long material in front thereof.

In addition, since the rotation direction of each of the pair of rollers is inclined obliquely upward with respect to the transport direction of the long material,
The frictional force acting between the inner peripheral surface of the pair of rollers and the surface of the long material pressed against the surface of the long material pressed from the inner peripheral surface of the pair of rollers onto the surface of the long material pressed against the same. A traction force acts obliquely upward with respect to the transport direction. Then, the upward component force of the traction force acts to push the long material sandwiched between the pair of rollers upward. Then, the long component is prevented from falling below the pair of rollers by its own weight due to the upward component force of the traction force.

In addition, a stopper roller abutted on the upper edge of the long material to be conveyed near the pair of rollers is sandwiched between the pair of rollers. Between the rollers is prevented from rising upward. And the long material being conveyed by being sandwiched between a pair of rollers,
It can be kept at a certain height.

Further, the stopper roller keeps rolling on the upper edge of the long material while abutting on the upper edge of the long material conveyed near the pair of rollers. Then, the frictional force acting between the stopper roller and the upper edge of the long material is reduced.

Then, the long material is continuously supported by the pair of rollers and the stopper roller such that the long material can be smoothly transported between the pair of rollers in a substantially horizontal direction corresponding to the transport direction while being held at a fixed height position.

Further, in the support device of the present invention in which the peripheral surfaces of the pair of rollers are covered with the elastic body, the surface of the long material is pressed against the peripheral surface of the roller via the flexible elastic body. Then, the surface of the long material is prevented from being damaged by the peripheral surface of the roller.
