Simultaneous Deposition of Different Elongated Elements in Tire Building
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for building tires are unable to simultaneously deposit pairs of elongated elements that are different from each other on a forming drum without requiring redesign or modification of existing extrusion and building lines, which is costly and inefficient.
Innovation Solution
A method that allows for the simultaneous deposition of pairs of elongated elements with different compositions and geometries on a forming drum by using pre-existing extrusion lines and building lines, where the elongated elements are initially wound on separate winding supports and then transferred to final winding supports for simultaneous unwinding and deposition, utilizing service components to maintain structural consistency and prevent sticking.

Engineering Contradiction Analysis
1Adaptability or versatility
If pairs of elongated elements that are different from each other are simultaneously deposited on a forming drum, then tire production versatility is improved, but existing extrusion and building lines require costly redesign or modification
Solution Approach 1:
The system segments the handling of different elongated element types by providing separate initial winding supports (first initial winding support and second initial winding support) for different types of elements. This segmentation allows each winding support to be optimized for specific element types while maintaining the ability to process multiple types simultaneously through the transfer mechanism.
Solution Approach 2:
The patent introduces intermediate transfer winding supports (first and second transfer winding supports) as mediators between the initial winding supports and the final winding support. These intermediary components enable the transfer and mixing of different elongated element types without requiring modification of the existing extrusion lines, thus achieving versatility while preserving existing infrastructure.
2Manufacturing precision
If separate winding supports are used for different elongated elements, then element differentiation is improved, but the number of winding supports and system complexity increases
Solution Approach 1:
The patent merges the functions of multiple winding supports by providing a first initial winding support and a second initial winding support that can each handle different types of elongated elements. These are then combined through transfer winding supports that consolidate the different element types onto a single final winding support, achieving both differentiation and consolidation.
Solution Approach 2:
The system employs dynamic transfer mechanisms that can selectively transfer different elongated elements from their respective initial winding supports to the final winding support. This dynamic capability allows the system to adaptively handle different element types and configurations without requiring permanent dedicated infrastructure for each type.
