Method and apparatus for making a corrugated fiberboard honeycomb structure

摘要: An improved method and apparatus for forming cellular core structures from corrugated fibreboard utilizing flat sheets of single wall board rectangular configuration. The are fed end one at a time in the direction flutes into rotary die cutting station to form parallel array evenly spaced cut lines extending perpendicular flute-feed side edge other each sheet. Each line is defined by an alternating series very long cuts short individually another along uncut sheet material connecting portions thereby plurality strips intermittently integrally joined portions. crease extend arranged pairs apart closely flanking Individual glue spots applied outer surface least top bottom facings between selected which be juxtaposed portion facing opposite strip having no spot thereto. then formed honeycomb-formable juxtaposing face thereon thereon, with first second lengthwise strip.
