Effect of Scoring Condition on Creasing Characteristics of Double-Wall Corrugated Board

A prototype-rotary creaser was experimentally applied to an AB double-wall corrugated fiberboard to reveal creasing characteristics of Grooming Applications the corrugated fiberboard and mechanical factors on failures of its height wise crease.Through this work, the followings were obtained.(1) There are appropriate combinations of pre-creaser gap and main-creaser gap for restricting the failure occurrences in the inside liner; (2) The pre-stage creasing for crushing corrugated medium was severely necessary for reducing the failures of the inside liner and performing the high-precision positionment for bending; (3) Dependency of water content and feed velocity on the failures of SPORT PLUS DEODORANT the inside liner was revealed.
