Gable Press for Composite Packaging Sealing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing apparatuses and methods for producing composite packaging with a decreasing cross-sectional area in the pour-out direction are complex and inefficient, requiring separate production processes and multiple mandrel wheel positions for folding and sealing the gable region.
Innovation Solution
An apparatus with a gable press assigned to a single mandrel wheel position for folding and sealing all gable faces to the pouring element and sealing protruding ears, reducing the number of mandrels needed and allowing for more efficient energy use, using heating and pressing, welding, or bonding methods to create gas- and water-tight connections.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Shape
If separate production processes in separate mandrel wheel positions are used for folding and sealing gable faces, then the packaging can be produced with decreasing cross-sectional area, but the production process becomes complex and inefficient
Solution Approach 1:
The patent combines multiple production steps (folding and sealing of gable faces) into a single mandrel wheel position. The gable press is designed to perform both folding and sealing operations simultaneously on all four gable faces in one position, eliminating the need for separate positions and reducing process complexity while maintaining the desired packaging shape.
2Reliability
If multiple mandrel wheel positions are used for folding all four gable faces, then complete sealing is achieved, but the number of production processes increases and efficiency decreases
Solution Approach 1:
The gable press combines all folding and sealing operations for the four gable faces into a single mandrel wheel position. The press mechanism is designed with multiple pressing elements that can simultaneously fold and seal all gable faces in one operation, achieving complete sealing while maximizing production efficiency by eliminating redundant positioning steps.
Solution Approach 2:
The gable press is designed as a multi-functional device that can perform multiple operations (folding and sealing) on multiple gable faces simultaneously within a single mandrel wheel position. This universal device replaces what would otherwise require multiple specialized positions, thereby improving productivity without compromising sealing reliability.
3Manufacturing precision
If separate positions are used for folding and sealing operations, then each operation can be optimized, but the number of mandrels needed increases
Solution Approach 1:
The patent merges the folding and sealing operations into a single integrated gable press mechanism that operates at one mandrel wheel position. This consolidated approach maintains manufacturing precision by designing the press to perform both operations in sequence within the same position, while reducing the number of mandrels required compared to using separate positions for each operation.
4Reliability
If multiple mandrel wheel positions are used for gable face processing, then thorough sealing is achieved, but energy consumption increases
Solution Approach 1:
The gable press combines all sealing operations for the four gable faces into a single mandrel wheel position, performing folding and sealing in one integrated operation. This reduces the total number of heating and pressing cycles required, thereby lowering energy consumption while maintaining thorough sealing quality through the coordinated action of multiple pressing elements.

AI summary
An apparatus for producing packaging, in particular composite packaging for liquid foodstuffs, having a cross-sectional area that decreases in the pour-out direction in the gable region. The packaging is composed of a sleeve having a gable region having a plurality of gable faces and a pouring element. The apparatus has at least one rotatable mandrel wheel having a plurality of mandrels for holding the sleeves. Additionally, a method for producing such packaging and a gable press for use with the aforementioned apparatus. In order to allow easier and more cost-effective production, it is proposed that the apparatus has a gable press, assigned to a single mandrel wheel position, for folding the gable region, for connecting all the gable faces of the gable region of the sleeve to the pouring element and for sealing the protruding ears in the same mandrel wheel position.
