A sheeter device capable of producing a full-width continuous sheet of masa comprising a scraper assembly (763) provide with ultrasonic horns (732) placed in close proximity to a sheeter roller (740), thereby scraping the sheeted dough (721) from the roller. The ultrasonic vibration precludes the buildup of dough on the horns. The invention eliminates the need for sheeter wires and their accompanying plastic bands while increasing the dough throughput of the sheeter.
