This work aims on the effect of temperature on the strength of adhesive joints of coniferous wood furniture edges. The objective of the research was to determine the difference between hot melt ethyl-vinyl-acetate (EVA) and hot melt polyurethane (PUR) adhesives. The main focus was devoted to the maximum achievable strength of bonded joints at different temperatures. The peeling test at an angle of 90 degrees and a shear pressure test at an angle of 45 degrees were performed to test the strength of joints to resist the stress. The data had been analyzed using analysis of variance (ANOVA) method to compare the strenght mean values of glues with each other. The results show that PUR glue achieves higher resistance in peel as it withstood the stress even at 70°C. The oblique shear pressure test results were however not possible to compare because of exceeding the measuring range limit of the ripping device while testing PUR adhesive samples. Based on the data it can be summarized that melt PUR adhesive for furniture edge banding is more convenient than EVA adhesive which does not reach the required strength in both types of tests conducted.
