Claw Type Corrugator Roll: The old single facer machine uses a guide claw plate made of copper sheet (also known as a copper knife or guide paper sheet).
Vacuum Inner Suction Type Corrugator Roll: The bottom corrugator roll of the vacuum suction type is processed with semi-circular or circular suction grooves evenly distributed in proportion, and connected to the suction holes evenly distributed on the roller body wall.
Positive Press Type Corrugator Roll: The positive pressure single facer machine forms a vacuum in the scraping roller, pasting roller, and corrugated roller parts, and then blows air into them to firmly press the corrugated paper onto the corrugated rollers.
