ABSTRACT:
Means are provided for feeding a succession of sheets of a sheet material along a path in a transport direction, with means along the path for applying a reinforcing strip to a sheet advancing in the transport direction beginning substantially in alignment with a leading edge of the sheet, and a cutting device along the path for severing the strip while the strip is advancing in the transport direction so that a trailing edge of the strip will not project beyond the trailing edge of the sheet, the cutting device having a lower cutting blade fitting between the strip and the sheet over a portion of the strip before the strip meets the sheet, an upper cutting blade juxtaposed with the lower blade above the strip and arranged so that the blade cuts the strip progressively inwardly from at least one edge, with solenoid means responsive to the trailing edge of the sheet for impulsively driving the upper blade toward the lower blade, and an electric circuit including a capacitor for discharging through the solenoid means impulsively actuate same.
