#### 3.1.1 The Influence of the Type of Glue on Quality of the Glued Joint
These findings collectively suggest that the selection of glue, application technique, preparation of the gluing surface, and gluing parameters are crucial in ensuring the strength and durability of edge banding. Edge banding improves corner joint strength compared with unbanded joints in cabinet furniture. The ultimate strength of cabinets constructed with edge banding was found to be 1.8 times greater than that of cabinets made without edge banding [18]. Based on the results of [PERSON] and [PERSON] [3], cabinets made of melamine-coated MDF with edge bands had a higher load-bearing capacity than cabinets made of uncoated MDF without edge bands. The type of edge banding material used also has a significant impact on the strength of the corner joints, with melamine edge banding material providing the highest diagonal tension and compression strength [4]. During the testing of the edge bonding quality (EN ISO 4624:2017 [21]), several factors were considered: the squareness of wood-based panels after processing by pre-cutters, position of the glue application roller, and angular deviation of the edge to the wider side of the panel. The properties of the particleboard (density, moisture content, and delamination strength of the layers) were considered but were not directly investigated [22]. The influence of glue parameters, including the glue temperature and method of application, was found to affect the bonding quality. The research indicated that the optimal glue temperature for the EVA adhesive used in this study was 210 \({}^{\circ}\)C, with an application quantity of 110 g/m\({}^{2}\) and a feed speed of 15 m/min. The gluing parameters were controlled using an automatic edge banding machine. Variations in these parameters can lead to changes in the bonding strength, with the highest strength observed in the samples with the smallest angular deviation from the edge to the wider side of the panel. The study also highlighted that the properties of the glue, such as its ability to fill gaps, are crucial, as evidenced by the performance of EVA glues in accommodating a gap created by a 2\({}^{\circ}\) slope. The study in [5] utilized SolidWorks simulation for both static and thermal analysis, applying mathematical finite element method (FEM) virtual modeling to assess the mechanical properties of ABS and oak veneer lamination materials, suggesting that oak veneer edges offer superior mechanical properties and adhesion to particleboard compared to ABS edges. During the peel-off testing phase (EN 28510-1:2014 [23]), researchers considered mechanical properties, such as resistance to peeling forces, which were evaluated using a standard test method. The thickness of the lamination material is another critical factor, as it was hypothesized to influence the strength and quality of the furniture. Their research indicated that a thicker edge band (i.e., 2 mm oak veneer) could potentially enhance the strength and quality of the furniture, as well as improve its resistance to peeling forces. Static analysis showed that the probability of deformation of furniture boards/elementsdecreased with thicker lamination, suggesting that thicker edges adhered more strongly to the particleboard. Additionally, thermal analysis revealed that the 2 mm thick ABS edge was the most heat-resistant, while the 1 mm thick oak veneer edge retained the most heat, indicating that the thickness also affected the thermal properties of the materials. This research also highlights the importance of considering the elasticity of lamination materials, especially for curved parts, where ABS's higher modulus of elasticity could reduce lamination issues. The findings of [PERSON] et al. [26] have significant practical implications for the furniture manufacturing industry, particularly for small- and medium-sized enterprises specializing in panel furniture with curved edges.
