PURPOSE: To let a Thomson's cutting blade for a trimming die be mechanically worked by providing both a carrying mechanism for a cutting blade member for bending works carrying in the cutting blade member to be bent, and a cutting blade bending mechanism bending the cutting blade member carried in by the aforesaid carrying mechanism for a cutting blade member for bending works.

CONSTITUTION: A cutting blade member pick-up mechanism 1 is provided, which is moved up and down, and picks up a cutting blade member 3 in continuous length to be stored in a cutting blade member hopper 2. The cutting blade member 3 thus picked up is sent forward in the direction of the length of the cutting blade member by a cutting blade member feed-in mechanism 4. When the cutting blade member 3 is sent to a specified position, sizing-cut is performed in response to the classification of the cutting blade by a cutting blade member cutting mechanism. Each cutting blade member to be bent out of the cutting blade members processed by sizing-cut is carried in to a specified position by a carrying mechanism for a cutting blade member for bending works 8. and the cutting blade member thus carried in is bent by a cutting blade member bending mechanism 9.
