> >Sandwich panelswith the corrugated filler made of composite cardboard are used in buildingconstructions, road sound dampening screens, etc. Taking into account that inindustries applying sandwich panels, the demand for such filler is relativelyhigh, the competitiveness of the product must be at a high level. This requiresdeveloping a high-performance industrial technology to produce it. Theseproduction processes include rotary shaping. The well-known technology formanufacturing corrugated cardboard from thin paper does not allow making veryhigh products. The article considers the possibility of producing relativelyhigh corrugated filler by creasing and folding. The important point here is tomake a flat pad, as one of the elements of the corrugation, at the point of itscontact with the skins of the panel. We studied two schemes of folding a preliminarilycreased cardboard web and evaluated the advantages of these schemes. Wesuggested the creaser shape and structure, which allow making high-qualityconnect pads on the corrugated cardboard within a wide range of sizes.
