Abstract
The method and the device serve for aligning a belt strip, which has a middle part and triangular end pieces. The belt strip is wound onto a tire building drum in such a way that the triangular end regions extend next to one another, at least in certain regions. At least one of the triangular regions is changed in its alignment, at least in certain regions. This achieves the effect that the triangular regions extend next to one another on the tire building drum with matching edge contours
Claims21
A method for aligning a belt ply that has a middle part and triangular end pieces having triangular end areas and which is wound onto a tire-building drum so that at least certain parts of the triangular end areas extend next to each other, the method including changing alignment of at least certain parts of at least one of the triangular end areas, and detecting a location of at least one cut edge, wherein a nominal value for aligning the cut edge of a rear triangular end area is derived from the detection of the cut edge of a front triangular end area.
A device for aligning a belt ply which comprises a middle part and triangular end pieces and which is wound up on a tire-building drum in such a way that at least certain parts of triangular end areas extend next to each other, the aligning device comprising:
- a measuring device;
- and an actuating device, wherein the alignment of at least certain parts of at least one of the triangular end areas is changed by the measuring device and the actuating device, wherein the measuring device comprises at least one camera that detects a location of at least one cut edge, wherein a nominal value for aligning the cut edge of a rear triangular end area is derived from the detection of the cut edge of a front triangular end area.
