Double-Sided Artificial Turf Yarn Confluence for Stronger Bonding

The patent merges multiple liquid supply functions into a single integrated manifold structure that distributes multiple raw solutions through a unified system. This allows two or more raw solutions to be supplied through spatially separated pipes that converge at a common injection point, ensuring sufficient bonding while maintaining structured distribution. The manifold integrates the supply of different liquids into one coordinated system rather than using completely separate injection mechanisms.

The patent applies local quality by providing spatially separated pipes for different raw solutions that maintain their individual flow paths until the injection stage. Each pipe can be optimized for its specific liquid's properties (viscosity, flow rate requirements), while the convergence at the injection point ensures proper mixing and bonding. This localized optimization along the flow path enables multiple yarn characteristics while ensuring reliable bonding where the solutions meet.

The patent introduces a manifold as an intermediary component that connects multiple separate pipe systems to a unified injection point. This intermediary structure maintains the simplicity of separate pipe routing for each raw solution while ensuring that all solutions converge properly at the injection stage. The manifold acts as a mediator that coordinates the flow from multiple sources into a bonded yarn structure, resolving the contradiction between process simplicity and bonding quality.
