This paper describes a pushing-cut process of a corrugated board (Cb) In a cutting process of Cb using a flat-bed die cutter, the occurrences of string-like dust was related to the offset position "e" of blade tip with an apex line position and also depended on the mechanical condition of sponge-rubber fixtures (SRF). In this work, in order to reveal the effect of the SRF on the out-of-plane crushing of inner flute, a 42 degree single wedge indentation to Cb was carried out by varying the height of SRF "h_R" under a specified offset position of e=2.0 mm. Through this experiment, it was found that the occurrences of Z-character folding of the inner flute was varied with h_R. although the current SRF condition was yet unstable and it should be furthennore investigated for reducing the eccentric upsetting of the inner flute in the lateral direction.
