Abstract
A trim guide device for slitter-scorers in which a corrugated board sheet transferred on guide tables is slit by rotary elements disposed above and below the corrugated board sheet, to be thereafter scored by similar rotary elements, comprising air ejection means disposed under the lower surface of those portion of said guide tables which are on the upstream side with respect to the flow of the corrugated board sheet of said rotary elements, and adapted to eject air toward the downstream side of the flow of the corrugated board sheet. The trims at both ends of the corrugated board sheet which has been subjected to slitting by means of said rotary elements are correctly guided by currents of air ejected from the air ejection means into the trim chute disposed on the downstream side of the guide table.
