Claims15
An abrasive article, the abrasive article comprising:
- a carrier body;
- and
- at least one abrasive layer with a main surface that faces away from the carrier body and a predefined thickness, the main surface of the at least one abrasive layer being arranged in segments on the carrier body,
- wherein at least two of the segments comprise visual indicators with a cross-section in the main surface of the abrasive layer, wherein the size, shape and/or location of the cross-section of each visual indicator in the main surface of the abrasive layer depends on the thickness of the abrasive layer where that visual indicator is located, wherein each of the visual indicators has a different height in the thickness direction of the abrasive layer, and wherein the visual indicators appear or disappear in a defined order during the use of the abrasive article while the thickness of the abrasive layer is reduced.
