Core Yarn Cabling Layout for Multi-Strand Needle Feeding
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current textile machinery systems are inefficient and inconvenient when trying to feed multiple yarn strands to a needle, as they require cabling yarns onto a single cone, which is time-consuming and limits pattern potential, and conventional creel designs can hinder easy servicing due to yarn mass accumulation.
Innovation Solution
A core cabling device that allows multiple yarn cones to feed in series or parallel through a single yarn guide tube, eliminating the need for cabling and enabling more than two yarns to be fed to a textile machine without using eyelets, featuring a framework of support members with cone holders that direct yarns linearly through each other and into a guide tube.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If yarn strands are cabled together onto a single yarn cone, then multiple yarn strands can be fed to a needle, but the process becomes time-consuming and inconvenient
Solution Approach 1:
The invention divides the yarn feeding system into separate cone holders, each holding a separate yarn cone. Each cone holder has its own guide tube, eliminating the need to cable yarns together. Multiple yarns are fed separately through their respective guide tubes to the needle, allowing pattern selection without time-consuming cabling operations.
Solution Approach 2:
The creel structure is designed with multiple cone holders that can each independently feed yarn to the needle. The system provides universal functionality where any combination of yarn cones can be used to create different patterns, and the same structure handles both single yarn and multi-yarn feeding requirements.
2Adaptability or versatility
If yarns are cabled onto a single cone, then multiple yarns can be supplied to a needle, but pattern potential is limited to two yarns when using magazine position
Solution Approach 1:
The invention segments the yarn supply system into multiple independent cone holders (at least three: active cone holder, magazine cone holder, and at least one additional cone holder). Each holder is equipped with its own guide tube, allowing any combination of yarns to be fed to the needle without the limitations of traditional two-position magazining systems.
Solution Approach 2:
The invention adds a spatial dimension to the yarn supply system by arranging multiple cone holders in different positions (vertical and/or horizontal arrangements). This dimensional expansion allows more than two yarns to be simultaneously available for pattern selection, moving beyond the limited two-position magazine constraint.
3Adaptability or versatility
If yarns are combined horizontally in a conventional creel, then multiple yarns can be fed to a needle, but yarn mass prevents easy creel servicing
Solution Approach 1:
The invention segments the yarn combination approach by providing separate guide tubes for each cone holder instead of combining all yarns into a single horizontal mass. Each yarn travels through its own designated path, keeping the creel structure open and accessible for servicing while still enabling multiple yarns to reach the needle.
Solution Approach 2:
The invention transitions from horizontal yarn combination (which creates mass accumulation) to vertical and/or three-dimensional yarn routing through separate guide tubes. This dimensional reorganization maintains yarn independence while improving creel accessibility for operators.
4Productivity
If conventional creel design is used with multiple yarn cones, then yarn can be supplied to the machine, but operator accessibility for servicing is reduced
Solution Approach 1:
The invention segments the creel structure into multiple independently accessible cone holders, each with its own guide tube. This segmentation allows the operator to access and service individual cone holders without disrupting the entire yarn supply system, maintaining productivity while improving servicing ease.
Solution Approach 2:
Instead of having yarns converge horizontally into a single access point (which blocks operator access), the invention inverts the approach by providing separate vertical/3D routing paths for each yarn through individual guide tubes. This inversion maintains yarn supply capability while opening up access to the creel structure.

AI summary
A core cabling device and method provides a first supply of yarn supported by a structure having a bore, such as a yarn cone, and a second supply of yarn that is then directed through the bore. As the first and second yarns are fed simultaneously, the first yarn winds, at least loosely, about the second yarn. It will become apparent that more than two yarns may be cabled together in such a manner.
