Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional carding apparatuses require separate processes and equipment to produce webs or rovings of different materials, making it a time-consuming and expensive process to combine fibers of various materials.
Innovation Solution
A carding apparatus with laterally spaced sections on the worker, stripper, and main cylinders, allowing fibers of different materials to be processed in parallel, enabling the production of multi-fiber webs or rovings in a single operation, with optional further processing through heated water sprays, steam chambers, microwave units, and die processes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If separate carding apparatus are used to produce webs of different materials, then each material can be processed independently, but the production process becomes slow, time-consuming and expensive
Solution Approach 1:
The patent combines multiple carding sections for different materials into a single carding apparatus. The worker cylinder, stripper cylinder, and main cylinder are divided into laterally spaced sections, each capable of processing a different fiber material simultaneously, thereby merging multiple production lines into one unified system that increases productivity while maintaining material-specific processing capabilities
Solution Approach 2:
The carding apparatus is segmented into laterally spaced sections on the worker, stripper, and main cylinders. Each section is defined by raised bands and is equipped with its own feed shoot, allowing independent processing of different fiber materials within the same apparatus. This segmentation enables parallel processing of multiple materials without interference
2Ease of manufacture
If separate carding apparatus are used for different materials, then each material can be processed separately, but the overall system complexity increases
Solution Approach 1:
The patent merges multiple carding functions into a single integrated apparatus. By combining laterally spaced sections for different materials within one machine, it eliminates the need for multiple separate carding apparatus, thereby reducing system complexity while maintaining the capability to process different materials independently
Solution Approach 2:
The carding apparatus is designed with universal multi-functionality, where a single machine can process multiple different fiber materials simultaneously through its laterally spaced sections. Each section can be configured for specific materials, but the overall apparatus serves multiple functions that would otherwise require separate dedicated machines
3Productivity
If multiple feed shoots are used to feed different fibers, then different materials can be processed in laterally spaced relation, but the cylinder design becomes more complex
Solution Approach 1:
The worker, stripper, and main cylinders are segmented into laterally spaced sections by raised bands. Each section corresponds to a specific feed shoot and is equipped with card wires arranged to process the assigned fiber material. This segmentation allows the cylinders to handle multiple fibers simultaneously while maintaining a relatively simple and systematic design structure

AI summary
A method of forming carded fibers of different materials. A feed system has a plurality of separate laterally spaced chambers containing fibers of different materials. The different fibers are fed in separate laterally spaced paths into a carding apparatus having a plurality of rollers and cylinders each having laterally spaced sections in alignment with the laterally spaced paths to receive and maintain the different fibers in the laterally spaced paths thereon as they move through the carding apparatus. The different fibers are combined into a multi-fiber roving or web after they exit the carding apparatus. Depending on the composition of the different fibers, they may be combined by conveying them through a humidifying and heated chamber or chambers.
