Abstract: Disclosed is a corrugated paperboard box making machine which comprises a sheet feeding apparatus, a processing apparatus, a folder-gluer, a counter-ejector for stacking the box-structured corrugated paperboard sheets and separating them as a batch, a speed setting unit for setting a sheet feeding speed, and a control apparatus. The control apparatus is operable to execute a sheet feeding control processing of the sheet feeding apparatus such that a sheet feeding operation of feeding one corrugated paperboard sheet is successively repeated a number of times corresponding to the number of the given number of box-structured corrugated paperboard sheets in the batch, and a sheet feeding stop control processing of, when the sheet feeding speed is greater than an allowable speed, the sheet feeding apparatus such that the sheet feeding operation is stopped at least once after execution of the sheet feeding control processing.

Abstract: A machine for making corrugated paperboard boxes form corrugated paperboard sheets includes a slotter device with a blade that forms slots in the corrugated paperboard sheet. The machine can handle various sizes and configurations of corrugated paperboard sheets and can determine if the blade of the slotter device has a suitable length to form slots in each of the various corrugated paperboard sheets, using parameters including a circumferential length (N) of the slotter cylinder and dimensions (E, F, G) of the corrugated paperboard sheet.
