Perforated Support Layer for Uniform Absorbent Fibre Deposition
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The non-homogeneous structure of the support layer strip in absorbent bed pads causes uneven distribution of absorbent fibres, affecting the quality of the produced pads.
Innovation Solution
Perforating the support layer strip along its entire width to uniform the air flow resistance, ensuring homogeneous distribution of absorbent fibres.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If the support layer strip is used without perforation, then the structure remains intact and simple, but the air flow resistance is non-uniform causing inhomogeneous distribution of absorbent fibres
Solution Approach 1:
The support layer strip is transformed into a porous material by creating perforations (holes) throughout its structure. This allows uniform air flow through the strip, ensuring homogeneous distribution of absorbent fibres during the deposition process while maintaining the structural integrity and functionality of the support layer.
2Manufacturing precision
If the support layer strip is perforated, then the air flow resistance becomes uniform improving fibres distribution, but the structural integrity may be compromised
Solution Approach 1:
The support layer strip is transformed into a porous material by creating perforations (holes) throughout its structure. This allows uniform air flow through the strip, ensuring homogeneous distribution of absorbent fibres during the deposition process while maintaining the structural integrity and functionality of the support layer.
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
Achieves a uniform distribution of absorbent fibres, enhancing the quality and consistency of absorbent pads.
Implementation Method 1
The fall of the absorbent fibres is aided by an air flow which, coming from the deposition device, passes through the support layer strip and the conveyor belt
Implementation Method 2
Perforating the support layer strip along its entire width to uniform the air flow resistance

AI summary
An apparatus for producing absorbent bed pads or absorbent pet mats, of the type having an absorbent core with a support layer and a plurality of absorbent fibres arranged on a first surface of the support layer. The apparatus includes a deposition station with a conveyor belt movable along an advancing direction (A) and configured to support a support layer strip, and a deposition device configured to generate an air flow passing through the conveyor belt and deposit the plurality of absorbent fibres onto a deposition surface of the support layer strip. The apparatus also includes a preparation station arranged upstream of the deposition station along the advancing direction (A) and having perforating members configured to perforate the support layer strip along its entire width. A method that can be carried out by the apparatus.
