摘要

The article discusses the influence of some technological factors on the through feed wrapping of wood-board materials with foils. For the aim of the study particle board details with dimensions 350/50/18 mm have been used. The specimen details were wrapped through feed at an automatic panel wrapping machine “FUX Austria” with polyvinyl chloride (PVC) foil. The used materials in the experimental operation were as follow: particle board from ?Kronospan” company and PVC foil made by ?Hornshuch“. The wrapping of the specimen details was made with reactive hot melt polyurethane glue Purmelt QR 5300 from ?Henkel”- Germany. The main characteristic of the adhesive connection between the materials is its adhesion strength. In this relation, the tensile strengths of the compound has been determined, perpendicular to the plane of adhesion. The influence of the following technological factors on the adhesion strength was also investigated: temperature of glue, quantity of glue, feeding speed. Three-factor experiment has been accomplished at three levels of the factors values. The adhesion strength has been determined following the RAL RG 716/1 standard, Part 7, according to DIN 16 860. The experimental data were processed using the regression analyses method and a mathematic equation has been done to determine the relationship interrelation between the factors and the output data value. The dependencies are presented by graphics and the results are analyzed.
