<p>A profile (23) definition system for use with profile bending apparatus using an imaging process. A profile (23) such as that used to form a cutting knife is located above a non-reflective surface (31) such that the profile configuration (23) can be imaged through a camera (32) substantially mounted above it. The profile (23) being illuminated from above. The camera image being captured by a frame grabber device (35) such that the profile configuration (23) can be compared in comparator means with a desired profile shape. Dependent upon the comparison further profile strip feed and/or bend operations may be performed in order to bring into substantial agreement the actual strip profile (23) and the desired strip profile.</p> |
