Abstract:
A method for changing the blade setting of a slitter-winder, comprising the steps of:advancing a web in a machine direction through the slitter-winder, a cross machine direction being defined perpendicular to the machine direction; slitting the web into a plurality of component webs of first widths and a first edge trimming of a second width by passing the web over blades located at first positions spaced from one another in the cross machine direction, the first edge trimming being defined along a first slitting line at a first cross machine position; changing the positions of the blades in the cross machine direction in order to slit component webs of widths different than the first widths and form a second edge trimming of a third width different than the second width, the second edge trimming being defined along a second slitting line at a second cross machine position, to thereby form a neck extending between the first edge trimming of a second width and the second edge trimming of a third width; and controlling a cutting apparatus with a control system to make a cut with the cutting apparatus between the first cross machine position corresponding to the first slitting line of the first edge trimming and the second cross machine position corresponding to the second slitting line of the second edge trimming.
