Method for producing protective packagings

摘要

A method for manufacturing of protective packaging, comprising attaching a bubble wrap (202) to the surface of cardboard (201), comprising the steps of cutting a sheet from the bubble wrap (202), the sheet having a size equal to the rectangular form of the cardboard, applying by a gluing unit (106) adhesive substance (203) on the whole surface of the rectangular cardboard form, attaching and pressing the bubble wrap sheet (202) to the form (201), the bubble wrap sheet comprising rows of bubbles, drying the cardboard with attached bubble wrap, cutting a desired die-cut of the packaging (330) on a die (320) equipped with cutting blades (321) and making creasing lines by using pairs of creasing knives (322, 323), wherein the creasing knives (322, 323) of each pair are set parallel to each other at a distance (D) larger than a distance (d1) between the neighbouring bubbles in a row and smaller than the diameter (d2) of a single bubble.
