Claims
- 1. A method of grinding an elongated material for a suture needle, comprising the step of reciprocally moving an elongated grinding tape in opposite directions along a longitudinal direction of said grinding tape, and simultaneously pressing the material against one face of said grinding tape in such a manner that the material is disposed substantially perpendicular to the longitudinal direction of said grinding tape and is inclined relative to said one face of said grinding tape, thereby grinding the material to form a cutting edge on at least one side edge of a grounded surface of the material.
- 2. A method according to claim 1, further comprising the step of moving said grinding tape in a predetermined one of the opposite directions along the longitudinal direction of said grinding tape after the grinding of the material by the reciprocal movement of said grinding tape is finished.
- 3. A method according to claim 1, further comprising the step of moving said grinding tape in a predetermined one of the opposite directions along the longitudinal direction of said grinding tape during the grinding of the material by the reciprocal movement of said grinding tape, the speed of movement of said grinding tape in said one predetermined direction being lower than the speed of reciprocal movement of said grinding tape.
- 4. A method according to claim 1, further comprising the step of varying the angle of inclination of said material relative to said one face of said grinding tape in a predetermined range during the grinding of the material by the reciprocal movement of said grinding tape.
