Corrugated paperboard cutting apparatus

Abstract

Abstract AFTER CORRUGATED PAPERBOARD IS COMPLETELY PREPARED BY PASTING PAPER FACING SHEETS TO OPPOSITE SIDES OF AN INTERMEDIATE CORRUGATED SHEET, THE RESULTING ELONGATED STRIP OF CORRUGATED PAPERBOARD MOVES OUT OF THE PASTING MACHINE TO CUTTERS WHERE THE STRIP IS CUT INTO SEPARATE SHEETS OF A LENGTH IN ACCORDANCE WITH THE SPECIFICATION OF A CURRENT PRODUCTION ORDER BEFORE THE SHEETS MOVE ALONG A CONVEYOR LINE TO ASUBSEQUENT WORK STATION. COMMON DRIVE MEANS FO THE CUTTERS AND PASTING MACHINE INCLUDE A PLANETARY GEAR HAVING A SPEED ADJUSTING GEAR FOR REDUCING THE SPEED OF DELIVERY OF PAPERBOARD FROM THE PASTING MACHINE WHEN NECESSARY SUCH AS WHEN A SUBSEQUENT PRODUCTION ORDER REQUIRES DIFFERENT LENGTH SPECIFICATIONS. MOREOVER, ADDITIONAL GEAR MEANS TOGETHER WITH A PHOTOELECTRIC CELL ARE PROVIDED FOR SENSING SUITABLE MARKS OR OPTICAL INDICIA AS PRINTED ON ONE SIDE OF THE PAPERBOARD STRIP AT REGULAR INTERVALS TO COOPERATE WITH OTHER SENSOR MEANS SUCH AS ANOTHER PHOTOELECTRIC CELL ASSOCIATED WITH THE CUTTERS FOR SENDING SEPARATE ELECTRICAL IMPULSES TO A SERVOMOTOR IN ORDER TO PROVIDE A SERIES OF SHEETS OF EQUAL LENGTH FOR A GIVEN PRODUCTION ORDER.
