Sequential Side Gusset Formation for Compact Packaging Machines
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing machines for producing packages with side gussets are cumbersome and costly due to simultaneous production of both gussets in a single station, limiting the size of packages that can be made.
Innovation Solution
A method and machine configuration where the two side gussets are produced sequentially in separate stations, allowing for more compact machine design and increased package size without increasing overall machine dimensions.

Engineering Contradiction Analysis
1Productivity
If both side gussets are produced simultaneously in the same station, then the machine can produce packages with side gussets, but the machine becomes very cumbersome and costly
Solution Approach 1:
The machine is divided into two separate stations: a first station configured to make only the first side gusset, and a second station configured to make only the second side gusset. This segmentation allows each station to be more compact while maintaining the overall package production capability, thereby reducing the cumulative machine size and cost.
2Volume of moving object
If packages are made with increased sizes, then the filling volume is larger, but the machine dimensions increase
Solution Approach 1:
By separating the gusset-making process into two dedicated stations rather than one complex station, the machine can accommodate larger package sizes without proportionally increasing overall machine dimensions. Each station handles one gusset independently, allowing for more efficient space utilization.

AI summary
The present invention relates to a method for forming packages of flexible material with a first side gusset and a second side gusset starting from a strip coming from a reel having a sliding direction. The method comprises the following steps: making the first gusset by folding close to a first side edge of the strip coming from the reel, and making the second gusset by folding the strip coming from the reel; in which the step of making the second gusset is performed on a portion of the strip which extends in the sliding direction after the step of making the first gusset was performed on the portion of the strip. Moreover, the present invention relates to a machine configured so as to carry out the method.
