Slotless Deckle Seal Strip with Self-Tapping Adapters
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing deckle board systems in paper machines require labor-intensive fastener removal and replacement for seal strip maintenance, leading to downtime and potential edge inconsistencies due to flexing seal strip clamps and lack of secure fastening.
Innovation Solution
A deckle board system with slotless seal strips and self-tapping connection adapters that anchor securely without fasteners, preventing movement in the machine direction and maintaining edge consistency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple fasteners are used to retain the seal strip in place, then the seal strip is securely fastened, but the maintenance process becomes labor intensive and results in additional downtime
Solution Approach 1:
The fastening system is segmented into modular components: the seal strip with integrated connection slots, the clamp assembly with fastening members, and the deckle board structure. This segmentation allows the seal strip to be quickly removed and replaced by only removing the clamp assembly, reducing maintenance time while maintaining secure retention during operation.
Solution Approach 2:
The system transitions from a static, permanent fastening to a dynamic, adjustable fastening system. The clamp assembly can be quickly attached and detached from the deckle board, and the seal strip can be removed from the clamp when needed. This dynamic design enables rapid maintenance while ensuring secure retention during normal operation.
2Reliability
If multiple fasteners extend through the seal strip, then the seal strip is securely retained, but the complexity of the system increases
Solution Approach 1:
The fastening components are merged into an integrated clamp assembly that combines the fastening member, the clamp body, and the connection to the deckle board into a single unit. This merging reduces the number of separate parts and simplifies the overall system while maintaining secure retention of the seal strip through the integrated fastening mechanism.
3Manufacturing precision
If the seal strip is flexing, then the edge formation may be uneven, but removing stock from edges decreases the width of the paper machine
Solution Approach 1:
The system applies preliminary anti-action by securing the seal strip to the deckle board before the paper-making process begins. The clamp assembly firmly attaches the seal strip to prevent any flexing or movement during operation, ensuring consistent edge formation without requiring stock removal to compensate for edge irregularities.
