Apparatus for measuring a cutting blade width in a cutting apparatus
First Claim
1. An apparatus for measuring a cutting blade width comprising:
- a movable head block to be mounted on a support frame and adapted to receive a cutting blade;
a detector to be mounted on a support member and operable to detect a predetermined radial orientation of a cutting blade;
a head block positioning device to be mounted on a support member and being operatively connected to said head block for moving said head block between a retracted position and a cutting position; and
a cutting blade edge detector to be mounted on a support member and operable to contact a cutting blade edge to detect the position thereof.

Abstract
An apparatus for measuring the width of a cutting blade in a linear motor is activated when the cutting blade is raised. A working pin is advanced and one end of a detecting pin is abutted against an edge of the cutting blade. Thereafter, the working pin is returned. The blade width is derived by deducting the number of inputted driving pulses in returning from the advanced position of the detecting pin. The cutting blade is polished each polishing cycle for predetermined times by polishing rollers. The width of the cutting blade is measured by blade width detecting means during each predetermined polishing cycle. The measurement value of the blade width is fed back into a control device so that the subsequent polishing time of the cutting blade with the polishing rollers is adjusted until it becomes appropriate. The expiration of the useful life of the polishing rollers is determined when a long polishing time is required.

6. A cutting apparatus comprising:
-
a cutting blade; a sheet material support surface; a movable head block to be mounted on a support frame and coupled to said cutting blade for reciprocating said cutting blade along an axis perpendicular to said support surface, wherein said blade is rotatably coupled to said head block; a support member; a detector operable to detect a predetermined radial orientation of said cutting blade; a cutting blade rotator mounted on said support member and operable to rotate said cutting blade about an axis perpendicular to said sheet material support surface; a head block positioning device mounted on said support member and operatively coupled with said head block for moving said cutting blade between a cutting position and a retracted position; and a cutting blade edge detector mounted adjacent said cutting blade and operable to engage said cutting blade and detect the position of an edge thereof when said blade has been retracted and positioned in said predetermined radial orientation. - View Dependent Claims (7, 8, 9, 10, 11, 12)
