Abstract:
A universal and precise stapling assembly comprising:(a.) a moveable stapling head for driving staples at precise locations through an aligned set of sheets on a given sheet alignment apparatus being one of a sheet-edge type alignment apparatus and a sheet-center type alignment apparatus; (b.) a drive device coupled to said stapling head for moving said stapling head relative to said given sheet alignment apparatus, and relative to the aligned set of sheets on said given sheet alignment apparatus; (c.) a sensor for sensing a position of the aligned set of sheets, said sensor comprising a sheet presence sensor, and said sheet presence sensor being mounted on and for movement with said stapling head; and (d.) a programmable controller connected to said drive device, to said sensor, and to said stapling head, said programmable controller including programmed type of sheet alignment apparatus information and calculating means for precisely calculating a precise staple location responsively to said programmed type of sheet alignment apparatus information and to the sensed position of the aligned set of sheets, thereby reducing staple mislocation due to a tolerance stack-up from components of said stapling head and tolerance stack-up from components of said given sheet alignment apparatus.
