| Title of the article | Causes of defects in sandwich-type panels during their production on lines with roller thermal press |
| Abstract. | Problem statement. In the manufacture of sandwich panels with metal cladding and a middle layer of individual filler sheets using in-line technology, a transverse joint of the middle layer occurs arbitrarily in the finished panels, located arbitrarily along the length of the panel. The technology for the production of sandwich panels on production lines with a thermal press, based on the principle of rolling a sandwich billet between the upper and lower roller installations, already implies the presence of panel defects in the form of «non-adhesive» cladding. The aim of the work is to identify the causes of defects in the sandwich panels during their production on the lines with roller thermal press. Results. The main results of the study are to identify the causes of the indicated defects, namely the presence of a difference in the thickness of the filler and the appearance of additional force acting on the side of the rollers on the moving skin at the jump points of the thicknesses of the joined sheets of the filler, as a result of a change in the direction of speed of the rollers. Conclusions. The significance of the research results for the construction industry lies in the fact that, based on an understanding of the mechanics of the occurrence of defects, the research results can be used to improve the equipment for the production of sandwich panels and, in general, to improve the quality of production of building envelopes. |
