Stainless Steel Offset Printing Machine Sucker

Description and Function

• Function: The primary role of the suckers (also known as vacuum pads or suction cups) is to physically grip the top sheet of paper from the feed pile using vacuum pressure and transport it into the printing units.
• Material: They are typically made from a durable, flexible rubber or similar elastomer to create a secure, consistent seal on the paper's surface without causing damage.
• Placement: Suckers are a key part of the automatic feeding system, often a multi-sucker universal or vacuum front feeder.
• Purpose: By securely holding and moving the paper, the suckers prevent misfeeds, ensure accurate alignment (registration) of the paper as it passes between the blanket and impression cylinders, and facilitate the high-speed, consistent operation of the press.
• Types: They come in various shapes and sizes (e.g., round, bellows) depending on the specific machine model (like Heidelberg or Komori) and the type of material being handled (paper, cardstock, non-woven bags, etc.).
