Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a flexible filament material having a bent portion or a flexible filament material having a bent portion and having a tube attached thereto for conveying the flexible filament material. The present invention relates to a material conveying device.

[0002]

2. Description of the Related Art A conventional flexible filament material having a bent portion or a flexible filament material having a bent portion and a tube attached thereto is a flexible filament material. Was held by a pair of rubber rollers at a plurality of locations and conveyed by rotation of the rubber rollers. In a flexible linear material conveying device, since the linear material is flexible, the linear material is twisted, and it is difficult to make the bending direction of the bending portion and the holding direction by the roller constant. For this reason, the bending force of the bending portion is often pressed by the holding force of the rubber roller in the bending direction of the bending portion to restore and deform the bending portion.
Further, when the flexible linear material on which the bent portion is formed and the tube is mounted is conveyed, similarly, the bending portion is restored and deformed by the gripping force of the rubber roller. Sometimes it went off.
