A tire testing apparatus for testing a tire comprises a loading means for the tire (), a measuring head () which is movable relative to the tire (), and lower bearing elements () on which the tire () can be positioned in vertical position. To improve such tire testing apparatus, the tire testing apparatus comprises upper bearing elements () which are movable relative to the lower bearing elements () and which together with the lower bearing elements () form a holder for the tire (). (FIG.)

Tire testing apparatus and method for testing a tire

A tire inspection apparatus for the optical inspection of a tire () comprises a housing with a support surface () for the tire () to be inspected; several measuring heads (), each of which comprises an optical measuring system, for inspecting the inside tread surface () and/or the external lateral surface () of the tire (); and a positioning device () for moving some or all of the measuring heads (--) into a rest position and into a measuring position. To improve a tire inspection apparatus of this type, the measuring heads (--) and the support surface () are installed without freedom of rotation.

Tire inspection apparatus, tire inspection system, and method for inspecting tires

In a method for detecting the deformation of objects (), a sequence of pictures of the object () is taken with a measurement method during the deformation of the object (). From the pictures, phase images are determined. To improve such method, there is formed the difference between the current phase image or the respective current phase image and the phase image of an initial state. This difference or these differences is/are evaluated and/or displayed on a visual display unit and/or stored.

Method and apparatus for detecting the deformation of objects

A tire testing facility used for testing tires includes a tire testing device with one or more testing heads () for testing the inner running surface () of the tire () and one or more testing heads () for testing the outer sidewall () side wall of the tire ().

Tire testing facility

A procedure serves for the testing of tires by means of a testing system. The testing system includes a memory in which geometric data () of the tire () are stored, and at least one probe () for testing the tire () surface. To improve on such a device, the probe or probes () are positioned with due consideration for the geometric data (-) of the tire () for the testing of the tire () surface (FIG.).

Procedure and device for testing tires

A process serves to record the deformation of objects (). In order to facilitate reliable evaluation even in the case of relatively large deformations, during the deformation of the object () a sequence or series of images of the object is recorded with a measuring process. The differential between two sequential images is formed. These differentials are integrated (FIG.).

Process and apparatus for recording the deformation of objects

The present invention relates to an inspection apparatus for tires having a positioning device for the tire to be inspected and a laser inspection device. In accordance with the invention, the inspection device comprises several measuring heads, in particular laser measuring heads in order to reduce the inspection time. In accordance with one aspect of the invention, several observation units and associated lighting sources are integrated in each measuring head.

Inspection apparatus for tires

A method serves the direct phase-angle measurement of radiation, in particular of light radiation which is reflected from a body. The body is exposed to coherent radiation. The radiation reflected from the body is imaged by an imaging optical system ( ) in an image plane in which a sensor is located. A reference radiation generated in accordance with the shearing method is superimposed on the sensor. The phase of the radiation from the body is determined from the measurement signals of the sensor. To improve such a method, the imaging optical system ( ) possesses a diaphragm ( ) having one or two apertures ( ) (FIG. ).
