METHOD OF FOLDING CORRUGATED BOARD BLANKS FOR MANUFACTURING FOLDING BOXES AND INSTALLATION FOR IT

摘要

FIELD: printing.;SUBSTANCE: invention relates to a method and an installation for folding blanks (1) made from corrugated board for manufacturing folding boxes (2), wherein the blanks (1) are provided with grooves (11, 11a, 12), notches, perforations etc., oriented at least approximately parallel to the direction of the corrugations (10) of corrugated cardboard, and if necessary also transversely oriented, along which folding or bending can be carried out. Wherein into the area of at least part of grooves (11), notches, perforations etc. oriented at least approximately parallel to the corrugated board corrugations (10), along which folding is carried out, fluid is introduced before the folding process, thereby the corrugated board in the area of these grooves (11), notches, perforations, etc. becomes flexible.;EFFECT: invention provides high speed of folding blanks made from corrugated board for manufacturing folding boxes.;4 cl, 4 dwg
