METHOD AND APPARATUS FOR PRODUCING MULTILAYER CORRUGATED CARDBOARD

摘要

manufacture of double-sided corrugated multilayer cardboard. SUBSTANCE: method involves continuously laminating first corrugated filler onto facing for forming single-sided single-layer cardboard with corrugated surface; continuously laminating second corrugated filler onto single-sided single-layer cardboard for forming single-sided multilayer cardboard with corrugated surface; continuously laminating facing onto corrugated surface of single-sided multilayer corrugated cardboard for producing double-sided multilayer corrugated cardboard. First and second fillers have predetermined pitch and height of their corrugations, with mentioned parameters of first filler being other than such parameters of second filler. EFFECT: increased efficiency by improved structure of cardboard, increased protection of packed article and improved strength of packaging material. 16 cl, 5 dwg
