Tyre Reinforcing Element Deposition Deviation Compensation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional tyre manufacturing processes face issues with non-optimal deposition of reinforcing elements due to dimensional tolerances of surface layers on forming supports, leading to defects like overlapping or undesired spaces between elements.
Innovation Solution
A method and apparatus that detect deviations between actual and theoretical deposition profiles to calculate and adjust the actual deposition path, ensuring optimal placement of reinforcing elements on forming supports, such as toroidal or cylindrical drums, thereby avoiding defects and enhancing tyre quality.

1Productivity
If a theoretical deposition path is used for reinforcing elements, then the manufacturing process is simple and fast, but the deposition precision deteriorates due to dimensional tolerances of surface layers
Solution Approach 1:
The system performs preliminary detection of the actual deposition profile before defining the final deposition path. By measuring the actual surface geometry in advance and calculating corrective deviations, the system prepares compensation data that ensures precise element placement without requiring slow real-time adjustments during deposition
Solution Approach 2:
The system uses detection devices to measure the actual deposition profile and generates feedback signals that represent deviations from the theoretical profile. This feedback is processed to calculate corrected deposition paths, creating a closed-loop control system that automatically compensates for dimensional tolerances and ensures accurate element placement
2Ease of manufacture
If dimensional tolerances of surface layers are present, then manufacturing is easier and more flexible, but deposition quality deteriorates due to overlapping or undesired spaces
Solution Approach 1:
The system changes the deposition path parameters based on detected surface layer variations. By calculating deviation values from the theoretical profile and adjusting the deposition path accordingly, the system compensates for dimensional tolerances in surface layers, ensuring consistent element placement accuracy regardless of manufacturing variations

AI summary
A method for manufacturing a tire for vehicle wheels includes the steps of building a carcass structure, including at least one carcass ply associated with annular anchoring structures, on a forming support, building a belt structure in a radially outer position with respect to the carcass structure and building a tread band in a radially outer position with respect to the belt structure, wherein the at least one carcass ply, the annular anchoring structures and the belt structure each include at least one reinforcing element deposited in a radially outer position with respect to the forming support. The deposition of the at least one reinforcing element includes the steps of setting a first deposition path of the at least one reinforcing element on the forming support based upon a theoretical deposition profile; detecting the deviations between an actual deposition profile and the theoretical profile along the first deposition path, defining, based upon the deviations, an actual deposition path of the at least one reinforcing element on the forming support; and depositing the at least one reinforcing element on the forming support along the actual deposition path.
