FOLDED HONEYCOMB STRUCTURE CONSISTING OF CORRUGATED PAPERBOARD AND METHOD AND DEVICE FOR PRODUCING THE SAME

摘要

The invention relates to a folded honeycomb structure and to a method and device for producing said folded honeycomb structure from a corrugated core web. The folded honeycomb structure has a number of adjacent corrugated core strips which lie in one plane and are interconnected by cover layer strips. Said cover layer strips are folded about 180~ and are perpendicular to said plane. According to the inventive method for producing the folded honeycomb structure, interconnected corrugated core strips are produced first by makin g a number of longitudinal scores in a corrugated core web. These corrugated core strips are then alternately rotated through 90~ respectively so that th e cover layer strips fold and the folded honeycomb structure is formed. The device corresponding to this method consists of a number of rotating blades for making the longitudinal scores and a number of guiding elements for rotating the interconnecting corrugated core strips.
