Abstract
A testing device for testing a surface of a test object using an abrasion ribbon and a load body. The abrasion ribbon is guided from a provision device through a testing area, in which the abrasion ribbon can come into contact with the surface of the test object under the influence of the load body onto the abrasion ribbon, to a take-up device. The take-up device has a drive for moving the abrasion ribbon using the take-up device.
Claims15
A testing device for testing a surface of a specimen using an abrasion ribbon and a load body, comprising:
- the abrasion ribbon, the load body, a supply device, a testing area, a winding device, and a control device for controlling the testing device,
- wherein the abrasion ribbon is guided in sections from the supply device through the testing area, where the abrasion ribbon can be brought into contact with the surface of the test specimen under the influence of the load body, to the winding device,
- wherein the winding device has a drive for moving the abrasion ribbon using the winding device,
- wherein the abrasion ribbon is brought into contact with the surface of the specimen only if transport of the abrasion ribbon from the supply device to the winding device is interrupted, and
- wherein the abrasion ribbon is not in contact with the surface of the specimen during transport of the abrasion ribbon from the supply device to the winding device.
