Abstract
The invention relates to a device and a method for detecting, identifying and relocating defects in a material strip of great length. In order to enable defects to be relocated reliably and quickly with relatively little effort, the material strip is checked for defects, and position indicators are applied to the material strip continuously over its length. In the event of a defect being observed, an associated defect position indicator is stored, and during the subsequent relocation of a defect, a current starting position indicator is established, and the material strip is moved over a conveying length which is calculated from the established starting position indicator and the stored defect position indicator.
Claims20
A method for detecting, identifying and relocating defects in a material strip of great length, comprising:
- moving the material strip;
- checking the material strip for defects while the material strip is moving,
- applying position indicators to the material strip continuously over its length,
- in an event of a possible defect being observed, storing an associated defect position indicator;
- and
- during a subsequent relocation of a defect, establishing a current starting position indicator and moving the material strip over a conveying length which is calculated from the established starting position indicator and the stored defect position indicator.
A device for detecting, identifying and relocating a defect in a material strip of great length, comprising:
- a moving device for moving the material strip;
- an optical inspection device for observing a possible defect on the material strip while the material strip is moving;
- a marking device for continuously applying position indicators to the material strip;
- and
- a memory device, for storing defect measurement data from the optical inspection device together with an associated position indicator for the observed possible defect.
A device for detecting, identifying and relocating a defect in a material strip of great length, comprising:
- a moving means for moving the material strip;
- an optical inspection means for observing a possible defect on the material strip while the material strip is moving;
- a marking means for continuously applying position indicators to the material strip;
- and
- a memory means for storing defect measurement data from the optical inspection means together with an associated position indicator for the observed possible defect.
