Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing embossing machines lack flexibility, efficiency, and ease of use in changing embossing rollers, leading to limited versatility and increased complexity in producing different types of multi-ply web materials.
Innovation Solution
An embosser design featuring movable load-bearing structures that support multiple embossing rollers, allowing for easy selection and positioning of rollers into operating positions, combined with movable pressure rollers and fluid dispensers, enabling compact and efficient adaptation to various embossing patterns.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a revolver system or movable equipment with multiple embossing rollers is used, then the versatility of the embosser is improved, but the structural complexity increases significantly
Solution Approach 1:
The embosser is divided into multiple independent working positions (first working position with first embossing roller and first pressure roller, second working position with second embossing roller and second pressure roller). Each working position can be independently configured and operated, allowing versatility without requiring a complex unified system for all configurations.
Solution Approach 2:
The embossing rollers and pressure rollers are made movable along respective tracks, allowing dynamic reconfiguration of working positions. This enables the system to adapt to different embossing patterns and requirements while maintaining a relatively simple overall structure through controlled motion rather than fixed complex arrangements.
2Ease of operation
If embossing rollers are replaced using a bridge crane from a storage area, then the replacement process is simplified, but the replacement time and productivity are reduced
Solution Approach 1:
Multiple embossing rollers are pre-installed on the embosser at different working positions or ready positions. This preliminary preparation allows for rapid replacement by simply moving rollers along tracks or switching between pre-positioned rollers, eliminating the need for time-consuming crane operations and storage area access during production changes.
Solution Approach 2:
Tracks serve as an intermediary mechanism between the embossing rollers and the working positions. The tracks enable smooth, controlled movement and precise positioning of rollers, facilitating quick replacement and configuration changes without requiring complex handling equipment like bridge cranes.
3Stability of the object's composition
If multiple embossing rollers are supported on a fixed load-bearing structure, then the structural stability is improved, but the adaptability to different embossing patterns is reduced
Solution Approach 1:
The load-bearing structure incorporates movable components that allow embossing rollers and pressure rollers to move along defined tracks. This dynamic capability enables the system to adapt to different embossing patterns and configurations while maintaining structural stability through controlled, guided motion rather than fixed rigid arrangements.
Solution Approach 2:
The load-bearing structure is designed to support multiple embossing rollers and pressure rollers that can be positioned at different working positions. This multi-functional design allows the same stable structure to accommodate various embossing patterns and requirements, achieving both stability and adaptability through versatile component arrangement.

AI summary
The embosser includes two load-bearing structures that are mutually movable to approach and move away from each other. The first load-bearing structure supports a plurality of first embossing rollers that can be selectively brought to an operating position, in which they cooperate with a first pressure roller. The second load-bearing structure supports one or more second embossing rollers cooperating with a second pressure roller. The two support structures can be moved away from each other to allow the selection movement of the first embossing rollers.
