Transverse Fiber Channel Insert for Open-End Spinning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing open-end spinning devices face challenges in adapting to different fiber materials and require complex replacement procedures for fiber channel inserts, which can lead to inefficient spinning processes and reduced yarn quality.
Innovation Solution
A fiber channel insert with a main axis oriented transversely to the fiber channel axis, allowing for easy insertion parallel to the opening roller and facilitating the design of the entry area, with optional inclusion of fiber detachment areas and a sealing groove for improved accessibility and sealing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the fiber channel insert is oriented with its main axis in the direction of the fiber channel (prior art), then the insert can be inserted perpendicular to the opening roller axis, but the accessibility for replacement and the design flexibility of the entry area are limited
Solution Approach 1:
The fiber channel insert is rotated 90 degrees so that its main axis extends essentially transverse to the main axis of the fiber channel, changing the insertion direction from perpendicular to the opening roller axis to parallel with the opening roller axis. This dimensional change improves accessibility for replacement while maintaining design flexibility through the transverse orientation
2Adaptability or versatility
If the fiber channel insert is made exchangeable for adaptation to different fiber materials, then the adaptability improves, but the replacement procedure becomes complex requiring pivoting of the opening roller housing
Solution Approach 1:
By changing the insertion direction to parallel with the opening roller axis through transverse orientation of the insert, the replacement procedure is simplified from requiring pivoting of the housing to a straightforward axial insertion/removal operation, reducing device complexity while maintaining exchangeability for different fiber materials
3Adaptability or versatility
If the fiber channel insert contains only the fiber detachment area, then the adaptability and ease of replacement improve, but the sealing and structural integration may be compromised
Solution Approach 1:
The fiber channel system is divided into separate components: the fiber channel insert containing the fiber detachment area and the opening roller housing containing the sealing groove. This segmentation allows selective replacement of the insert for adaptability while the housing maintains structural integration and sealing reliability
Solution Approach 2:
The sealing groove in the opening roller housing acts as an intermediary element that ensures reliable sealing between the insert and housing. This mediator component maintains structural integrity and sealing reliability while allowing the insert to be exchanged independently

AI summary
A fiber channel insert (2) can be inserted into a receiving opening (12) of a dissolving roller housing (3) of an open-end spinning device (1), wherein the fiber channel insert (2) has a fiber channel body and contains a partial section of a fiber channel (9). The fiber channel body extends with its main axis (HA2) substantially transversely to a main axis (HA1) of the fiber channel (9). An open-end spinning device (1) with a spinning element (5) and a dissolving roller housing (3) in which a dissolving roller (4) is rotatably arranged, contains a fiber channel (9) which transports the fiber material (F) to be spun from the dissolving roller (4) to the spinning element (5). A partial section of the fiber channel is provided in a fiber channel insert (2) which can be inserted into a receiving opening (12) of the dissolving roller housing (3) and which has a substantially cylindrical fiber channel body.The fiber channel body extends with its main axis (HA2) essentially transversely to a main axis (HA1) of the fiber channel (9) and the fiber channel insert (2) can be used essentially parallel to the axis of the dissolving roller (AW).
