The Green Tire Uniformity Monitor utilizes Bytewise Very High Speed (2000 Hz) Profile Sensors to rotationally scan the green tire while it is still mounted on the tire assembly drum, and inspect the green tire for non-uniform geometry.
The Monitor is available as a mobile, tripod-mounted instrument suitable for analyzing the green tire after shaping and stitching. The mobile unit can also be positioned to monitor the placement accuracy and splice geometry for each component as it is applied to the TBM drum. This mobile instrument can be used to troubleshoot machine setups and alignments, and to verify set-up uniformity across all TBMs.
The monitor will soon be available in a version suitable for fixed-mounting on any TBM drum position. Traditional tire building machines apply numerous components sequentially on drums in order to build up, and then shape, the final green tire carcass. In highly-automated machines, small machine changes can adversely affect the cured tire uniformity. Such defects may not be detected until several hours of green tires have been produced. 100% monitoring of the green tire geometry helps assure that no bad tires are sent to curing.
