A tire (100) comprises an inner surface (102) defining and facing an inner hollow space (104), an outer surface (106) pointing away from the inner hollow space (104). A method of processing the tire (100) comprises identifying the position of a first feature (108) on the outer surface (106) and cleaning a surface portion (110) of the inner surface (102) of the tire (100), wherein the surface portion (110) has a first predetermined position relative to the position of the first feature (108) on the outer surface (106). A separate element is attached with its attachment surface (118) to the surface portion (110), wherein a ratio of a size of the surface portion (110) over a corresponding size of the attachment surface (118) is smaller than 10.

A tire marking device comprises a control device (114); a laser device (106); a tire positioning device (102) for positioning a first tire (108) with respect to the laser device (106) into a treatment position (111) to allow a marking of a marking region (110) of the first tire (108) with the laser device (106); an intermediate transport supply device (104), the intermediate transport supply device (104) being configured to be located for providing a second tire (136) to the tire positioning device (102); and a control device (114), the control device (114) being configured for operating the intermediate transport supply device (102) and the positioning device (102) in order to move the second tire (136) to the treatment position (111) and simultaneously remove the first tire (108) from the treatment position (111). The invention also relates to a method and to a control device for operating a tire marking device.
摘要:
The invention relates to a rubber article (100) comprises a cured polymer material (104) forming a surface of the rubber article (100), the surface comprising: a first surface portion (106); a second surface portion (108); the first surface portion (106) and the second surface portion (108) forming at least a part of a digital code pattern (102); the first surface portion (106) having a first optical reflectivity; the second surface portion (108) having a second optical reflectivity which is lower than the first optical reflectivity and a surface structure (112) in the second surface portion (108), wherein the surface structure (112) provided a second optical reflectivity which is lower than a first optical reflectivity of the first surface portion (106). The invention also relates to a method and device for identifying said rubber article and to a computer program product.
摘要:
Described is in particular a method of generating a transfer pattern (110) defining a digital code pattern. According to the described method, a digital code pattern definition (104) defining a plurality of light and dark portions is received, wherein each of such portion has a size A. The transfer pattern (110) is generated by rasterizing the digital code pattern definition (104) with structure pixels, in particular by mapping the digital code pattern definition into an array of equally sized structure pixels, wherein the size A of the light and dark portions is an integer multiple of a size B of the structure pixels. The array of structure pixels comprises at least two different types of structure pixels. Each type of structure pixel defines a certain surface structure on the rubber article, the surface structure causing a certain optical reflectivity of the structure pixel. Further, at least two types of structure pixels have a different optical reflectivity.
