Material Web Arrangement on Core Preventing Jamming
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for arranging material webs, such as ticket webs, on cores often result in jamming issues due to glue residues or the bent form of the first ticket, which can also affect label and sticker dispensing machines.
Innovation Solution
A method where a sheet of material is arranged on a core with the first end loose, and the material web is reeled and tightened with the first end located between the core and the sheet, providing friction without chemical or physical fixation means, preventing jamming in dispensing machines.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If the first ticket is attached to the core by glue or double sided tape, then the ticket web is securely held on the core, but glue residues cause jamming of the ticket machine
Solution Approach 1:
The harmful element (glue) is completely removed from the system. Instead of using glue to attach the first ticket to the core, the patent uses a mechanical arrangement where the first ticket is bent into a groove on the core periphery, eliminating glue residues that cause jamming while maintaining secure attachment.
Solution Approach 2:
The chemical attachment method (glue) is replaced with a mechanical attachment method (bending the first ticket into a groove). This substitution eliminates the harmful chemical residues while achieving the same functional goal of securing the ticket web to the core.
2Strength
If the core has a groove on its periphery and the first ticket is bent in the groove, then the ticket web is held on the core, but the bent form of the first ticket causes jamming of the ticket machine
Solution Approach 1:
The problematic bent first ticket is extracted or removed from the system. The patent introduces a separate sheet material that covers the core periphery, allowing the first ticket to be positioned between the sheet and core without being bent, thus eliminating the source of jamming while maintaining attachment functionality.
Solution Approach 2:
A sheet material is introduced as an intermediary element between the first ticket and the core. This sheet covers the groove on the core periphery and allows the first ticket to be held in place through friction and mechanical arrangement rather than bending, preventing jamming while achieving secure attachment.
3Object-affected harmful factors
If friction is used to hold the material web on the core without chemical or physical fixation means, then jamming is prevented, but the material web may not be securely held
Solution Approach 1:
Multiple attachment mechanisms are merged into a single system. The patent combines friction between the first ticket and the sheet/core arrangement with the mechanical structure of the sheet covering the core periphery, creating a multi-mechanism attachment system that provides both secure holding and jamming prevention.
Solution Approach 2:
The attachment mechanism transitions from chemical bonds (glue) to mechanical friction and pressure. By changing the fundamental parameter of attachment from chemical to mechanical, the system achieves both secure holding through friction and prevention of jamming by eliminating deformable bent tickets.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This approach ensures that the material web is securely held on the core without jamming the dispensing machine, allowing for smooth operation and easy release of individual tickets or labels/stickers.
Implementation Method 1
arranging a first end of the material web between the core and the first end of the sheet, and reeling and tightening the rest of the material web on the core, the first end of the material web locating between the core and the first end of the sheet during said reeling and tightening

AI summary
A method for arranging a material web on a core. The method comprises providing a sheet of material, arranging the sheet on the core such that a first end of said sheet is not attached but loose from the core, arranging a first end of the material web between the core and the first end of the sheet, and reeling and tightening the rest of the material web on the core, the first end of the material web locating between the core and the first end of the sheet during said reeling and tightening.
