Laminating System Insertion Sheet Adhesive Protection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing laminating systems face challenges in attaching laminate films to sheets without misalignment, leading to issues like peeling, wrinkles, and waste due to the adhesive layer adhering to rollers and conveying paths, especially when starting or ending sheets lack a preceding sheet for overlap.
Innovation Solution
A laminating system with a sheet feed section, continuous conveying section, and controller that feeds insertion sheets before or after the target sheet to ensure continuous and accurate attachment of laminate films, preventing adhesive issues and ensuring high-quality lamination.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the laminate film is conveyed without a sheet, then the adhesive layer adheres to rollers and conveying path causing conveyance trouble, but the laminating processing cannot be performed
Solution Approach 1:
The patent feeds a preceding sheet before the target sheet to be laminated. This preliminary action ensures that when the laminate film is conveyed, there is always a sheet present to prevent the adhesive layer from adhering to rollers and conveying path, thus maintaining conveyance stability while enabling laminating processing.
Solution Approach 2:
The patent introduces an insertion sheet as an intermediary element between the target sheet and the laminate film application process. This insertion sheet acts as a mediator that prevents direct contact between the adhesive layer and the conveying mechanism, eliminating conveyance troubles while allowing the laminating process to proceed normally.
2Reliability
If the leading sheet is attached at a predetermined distance from the leading end, then the adhesive layer is not exposed, but the leading sheet becomes a waste sheet due to misalignment
Solution Approach 1:
The patent feeds a preceding sheet before the target sheet, creating an overlap region. This preliminary action allows the laminate film to be attached to the preceding sheet at a position that prevents adhesive exposure, while the overlap ensures proper alignment with the target sheet, eliminating the need to discard the leading sheet.
Solution Approach 2:
The insertion sheet serves as an intermediary that carries the laminate film attachment. By attaching the laminate film to the insertion sheet rather than directly to the target sheet, the system achieves both adhesive layer protection and precise alignment through the overlapping configuration.
3Manufacturing precision
If the laminate film is attached to the leading sheet, then the leading end may float and peel off or generate wrinkles, but attaching at a distance creates waste sheets
Solution Approach 1:
The patent feeds a preceding sheet before the target sheet and attaches the laminate film to this preceding sheet in the overlap region. This preliminary action ensures that the laminate film is properly positioned and bonded before the target sheet is processed, preventing floating, peeling, and wrinkles while avoiding waste of the leading sheet.
Solution Approach 2:
The insertion sheet acts as an intermediary carrier for the laminate film. By using the insertion sheet as the attachment surface rather than the target sheet itself, the system achieves high-quality lamination without creating waste sheets, as the insertion sheet is part of the continuous sheet feed.
4Manufacturing precision
If insertion sheets are fed before or after target sheets, then continuous and accurate lamination is achieved, but the device complexity increases
Solution Approach 1:
The patent implements a sheet feeding control mechanism that feeds a predetermined number of insertion sheets before each target sheet to be laminated. This preliminary action automates the process of preparing the overlap region, ensuring consistent and accurate lamination quality while managing device complexity through systematic control.
Solution Approach 2:
The patent employs a controller that monitors and controls the feeding of insertion sheets based on the lamination process requirements. This feedback mechanism ensures that the correct number of insertion sheets is fed before each target sheet, maintaining high lamination quality while optimizing the complexity of the sheet feeding control system.

AI summary
A laminating system (1) includes: a sheet feed section (15, 25, 41) that feeds cut sheets; a continuous conveying section (24) that conveys the plurality of cut sheets fed by the sheet feed section without any interval between the cut sheets; a laminating section (26) which executes laminating processing of attaching a laminate film to the plurality of cut sheets conveyed by the continuous conveying section; and a controller (16, 21) that causes the sheet feed section to feed an insertion sheet at least before or after a target sheet on which the laminating processing is performed.
