Circular Comb Fitting With Segmented Teeth For Fiber Tension Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
High-speed combing machines face challenges in maintaining fiber quality and minimizing yarn defects due to increased tensile forces and kickback behavior during the combing process, especially with high numbers of combing cycles.
Innovation Solution
A comb set design with a first comb segment area having increasing combing effect counter to the rotation direction and a second segment area with decreasing combing effect, reducing tensile force and adjusting tooth configuration to minimize fiber tension and prevent hook formation, thereby ensuring high combing results and process reliability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If the combing effect is increased to improve fiber parallelization and combing quality, then the combing result is improved, but the tensile force on fibers increases causing yarn defects and kickback behavior
Solution Approach 1:
The comb clothing is divided into multiple comb segments (at least two) arranged in sequence along the rotation direction. Each comb segment has different tooth configurations (different tooth spacing, tooth height, or tooth pressure angle) to create varying combing effects at different positions, allowing the system to achieve both high combing quality and reduced tensile force through progressive tooth design
Solution Approach 2:
Different regions of the comb clothing have locally optimized tooth configurations. The tooth parameters (spacing, height, pressure angle) are specifically adjusted in different comb segments to create zones with different combing intensities, enabling localized control over combing effect and tensile force distribution along the fiber path
2Productivity
If high-speed combing operation is implemented to increase productivity, then the output increases, but the relative interference increases affecting soldering quality
Solution Approach 1:
The comb clothing design creates a dynamic combing effect that varies along the rotation direction. By progressively adjusting tooth parameters across multiple comb segments, the system adapts the combing intensity to match the fiber processing stage, enabling high-speed operation while maintaining consistent fiber quality and reducing soldering errors

AI summary
The invention relates to a comb fitting (1) for a comb roller of a textile machine rotatable about a rotary axis (4a), in particular of a combing machine and particularly for a circular comb, comprising at least one first and one second comb segment region (2, 3) disposed one after the other as seen in a direction of rotation (4) of the comb roller and formed by saw tooth punch parts (5) disposed adjacent to each other in the direction of the rotary axis (4a) and having teeth (7) extending away from a foot part (6), wherein a configuration of the teeth (7) within the first comb segment region (2) changes, so that the combing action of the teeth (7) opposite to the direction of rotation increases, and wherein the teeth (7) within the second comb segment region (3) are configured so that the combing action within the second comb segment region (3) is less than on the end (11) of the first comb segment region (2) as seen opposite the direction of rotation (4), and a configuration of the teeth (7) within the second comb region (3) changes so that the combing action of the teeth (7) is reduced opposite to the direction of rotation (4).
