Abstract: In a device for processing flat products using a processing tool which processes the product between the tool and a counter-tool, the processing tool is supported by an ultrasonic sonotrode. The processing tool performs a processing movement together with an ultrasonic sonotrode, wherein the processing movement results in a partial separation of the flat product.

Abstract: A method and apparatus for forming a starter notch along the length of a work-piece for subsequent fatigue testing. The starter notch is formed with a cutting wire such that it will promote fatigue-cracking in the work-piece in one defined direction and avoids cracking in directions other than the length direction of the starter notch. Improved fatigue-testing analysis may therefore be realized.
