Winding Support Rearrangement for Mixed Tire Building Elements
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing tire production processes struggle to simultaneously deposit two elongated elements that are different from each other on a forming drum without requiring redesign or modification of the extrusion and building lines.
Innovation Solution
A method involving the use of coupled winding supports to rearrange elongated elements on storage bobbins, allowing simultaneous deposition of different elongated elements on the forming drum using existing extrusion and building lines, by initially winding same-type elements on separate supports and then rearranging these supports to combine different elements for deposition.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If existing extrusion lines and building lines are used to deposit elongated elements, then production infrastructure is utilized, but the ability to deposit elements of different compositions and geometries simultaneously is limited
Solution Approach 1:
The patent divides the winding support into separate first and second winding supports that can be independently configured. Each winding support can hold elongated elements of different types, allowing the system to deposit varied elements simultaneously without redesigning the entire production line infrastructure.
Solution Approach 2:
The patent introduces movable and adjustable winding supports that can be reconfigured during operation. The winding supports can be positioned at different locations on the forming drum and adjusted to accommodate different elongated element types, enabling versatile deposition without permanent structural modifications.
2Productivity
If winding supports are coupled to wind elongated elements in parallel, then simultaneous deposition is enabled, but the complexity of managing multiple winding supports increases
Solution Approach 1:
The patent combines multiple winding supports into a coupled system where the first and second winding supports are connected and rotated together as a unit. This merging allows simultaneous winding and deposition of multiple elongated elements while simplifying control through a single rotational mechanism shared by all supports.
Solution Approach 2:
The coupled winding supports are designed to handle multiple types of elongated elements universally. Each winding support can accommodate different compositions and geometries, making the system multi-functional for various tire construction requirements without requiring separate specialized equipment for each element type.

AI summary
A method for arranging elongated elements to be used in a process for building tyres for vehicle wheels, including: winding in parallel a first elongated element and a second elongated element of a first type respectively on a first winding support and a second winding support coupled and rotatable about a first rotation axis; winding in parallel a third elongated element and a fourth elongated element of a second type respectively on a third winding support and a fourth winding support coupled and rotatable about a second rotation axis, where the elongated elements of the second type are different from the elongated elements of the first type; decoupling the second winding support from the first winding support and the fourth winding support from the third winding support; and coupling the second winding support with the third winding support and the fourth winding support with the first winding support.
