Net with Strasses Manufacturing Using Thermoadhesive Alignment Frames
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing methods for applying strasses to nets result in stiff and heavy fabrics due to the use of settings or complex adhesion processes, which limit the elasticity and flexibility of the net, and require high skill and dexterity, especially when dealing with wide meshes and small strasses.
Innovation Solution
A process that integrates the interlacement of the net and the application of strasses without using settings, by arranging strasses with a thermoadhesive base on a sheet-like support, which is then applied to a frame with notches and openings to align with the net threads, allowing for adhesion and connection during the formation of the net, using heat and pressure to solidify the adhesive layers.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If settings are used to attach strasses to net knots, then the strasses are securely fixed, but the net becomes stiff and heavy with limited elasticity
Solution Approach 1:
The invention extracts and eliminates the settings (metallic plates) from the net structure. Instead of using settings to attach strasses to net knots, the patent applies strasses directly to the net threads through a thermoadhesive layer, removing the unnecessary weight and stiffness introduced by settings while maintaining secure fixation
Solution Approach 2:
The invention introduces a thermoadhesive layer as an intermediary between the strass base and the net thread. This adhesive layer enables secure attachment of strasses without requiring settings, thereby maintaining fixation reliability while avoiding the weight and stiffness problems associated with traditional setting-based methods
2Reliability
If settings are used to attach strasses to net knots, then the strasses are securely fixed, but the net elasticity is greatly limited
Solution Approach 1:
The invention removes settings from the net structure, allowing the net to maintain its natural flexibility and elasticity. The direct application of thermoadhesive strasses to net threads does not impede the movement and stretching of the net, preserving ease of operation
Solution Approach 2:
The thermoadhesive layer serves as a flexible intermediary that bonds strasses to net threads without restricting net movement. Unlike rigid settings, the adhesive layer allows the net to stretch and flex freely while maintaining secure strass attachment
3Device complexity
If manual adhesion of strasses to net knots is performed, then strasses can be attached directly, but the process is complicated and requires high skill and dexterity
Solution Approach 1:
The strasses are prepared in advance with a thermoadhesive layer already applied to their bases. This preliminary preparation eliminates the need for operators to manually apply adhesive during the attachment process, simplifying the operation and reducing skill requirements
Solution Approach 2:
The invention replaces the manual mechanical process of attaching strasses to net knots with a thermal adhesion process. The thermoadhesive layer is activated by heat, automatically bonding the strasses to the net threads without requiring manual dexterity or complex manipulation
4Extent of automation
If opposite rollers are used to adhere strasses to nets, then application is automated, but centring small strasses on receiving sites in wide meshes is difficult
Solution Approach 1:
The invention applies the thermoadhesive layer locally on the base of each individual strass rather than using a continuous adhesive sheet. This localized application allows each small strass to be precisely positioned and centred on its receiving site, even in wide meshes, while maintaining automation through the thermal bonding process

Function Achieved in This Case
This method enables quick and efficient application of strasses to nets of any type, including those with wide meshes, resulting in flexible and elastic nets with brilliant optical effects, without compromising the net's elasticity or requiring high skill, and allows for graphic freedom in strass distribution and shape.
Implementation Method 1
a layer of thermoadhesive glue is applied, that is which becomes soft upon applying heat and adheres to the surface thereto it is applied

AI summary
A process for manufacturing a net with strasses allows obtaining nets equipped with strasses in a single solution wherein the interlacement of the net and the application of the strasses is implemented, in a quick way, without using settings, and by implementing nets of any type, even with wide meshes with respect to the sizes of the strasses and with complex drawings, and it comprises the steps of: arranging a plurality of strasses distributed according to a predetermined scheme on a support (3) with the exposed adhesive bases (2); stretching on a frame (5) one or more threads (10) so as to obtain a net wherein the crossings correspond to through openings (8) of the frame arranged according to said predetermined scheme; applying the support (3) on the frame by making to adhere the adhesive bases (2) of the strasses to the crossings of the net, by determining the adhesion of the crossings (11) with a permanent connection.
