Abstract:
1. A method comprising the steps of: providing a paperboard splicing machine having left and right sides defining therebetween an axial direction and comprising a splice head which has an alignment position, a splice roll, a clamping bar and a cutting plate having an axially elongated cutting edge upstream of the splice roll, wherein the splice roll and clamping bar define therebetween a space; providing a first paperboard roll having left and right ends which serve as left and right side edges of a first web of the paperboard roll, wherein the first paperboard roll is rotatably mounted on the paperboard splicing machine to rotate about an axially extending axis; inserting the first web upwardly through the space away from the first paperboard roll and then pulling the first web upstream away from the alignment position toward an operator over the splice roll and cutting plate so that some excess of the first web hangs downwardly from the cutting edge; after the steps of inserting and pulling, cutting the first web along the cutting edge to provide an axially elongated leading end edge of the first web which extends from the left side edge to the right side edge of the first web; operating a light-emitting device to produce an alignment marker which is formed of light and is displayed along the alignment position on an upper surface of the first web; clamping the first web between the splice roll and clamping bar; providing an image display device; viewing with the image display device an image of the leading end edge and an image of the alignment marker; and after the step of cutting, aligning the leading end edge at the alignment position during the step of viewing by the operator manually moving the first web downwardly through the space toward the first paperboard roll and moving the leading end edge downstream over the splice roll and cutting plate away from the operator toward the alignment marker and into alignment with or adjacent the alignment marker such that the operator views the step of moving the leading end edge downstream as moving the image of the leading end edge into alignment with or adjacent the image of the alignment marker; wherein the operator performs the steps of viewing and aligning while standing at an alignment and viewing position which is adjacent the first paperboard roll between the left and right ends of the first paperboard roll and at which the operator cannot directly see the leading end edge when the leading end edge is above and adjacent the splice head during the steps of viewing and aligning.
