摘要:
A bending method for a straight needle-shaped material which has a thickness decreased from a body portion to a needle point that is inserted between a roller having a processing surface and a belt and is wound around the roller via a separating member. Then the roller is rotated and the belt is wound, thereby pressing and curving the straight needle-shaped material onto the processing surface. In a suture needle, a portion of a tip side including the needle point is formed as a non-restricted portion which is not restricted by the processing surface of the roller, and a portion except for the non-restricted portion is formed as a curved portion which is bent along the processing surface of the roller.
