Abstract (en)
[origin: WO2020221502A1] The present invention relates to a method (S200) for forming a cardboard container (190). The method (S200) comprises: providing (S202) a web (110) of cardboard material, said web (110) having two opposing longitudinal edge portions (112, 114); helically winding (S204) the web (110); joining (S206) two adjacent longitudinal edge portions (156, 158) of the web (110) by sewing, thereby forming a cylinder (160) having a longitudinal extension; cutting (S208) a plurality of slits in the cylinder (160) by starting from a free edge portion (172, 173) of the cylinder (160), thereby forming flaps (182); and folding (S210) the flaps (182) along a direction (192) transverse to the longitudinal extension of the cylinder (160), thereby forming a cardboard container (190).
