ABSTRACT:
A slitting machine including a first slitting stage for producing a plurality of interrupted cut slits in an advancing sheet having a leading edge and a trailing edge includes a drive pulley, a driven pulley, and a belt engaging the drive pulley and the driven pulley to provide a power path and a return path between the drive pulley and the driven pulley. The slitting machine also includes a mechanism translating rotation of the driven pulley to drive an upper slitting assembly and notched blades of a lower slitting assembly in synchronization with the advancing of the sheet by a sheet feeder. A moveable idle pulley engages a portion of the belt in the power path, and an adjustment mechanism controls the moveable idle pulley to adjust the length of the power path, thereby varying the locations of the notches of the lower blades relative to the sheet being advanced, and thereby allows adjustment of the width of the margins at the leading and trailing edges of the advancing sheet to compensate for slippage of the advancing sheet due to variations in its thickness, type of material, and/or surface finish.
