A gripper bar is a mechanical device commonly used in printing presses, specifically in the newspaper industry. It is a horizontal bar equipped with a series of metal fingers or grippers that are strategically spaced to securely hold sheets of paper during the printing process.
The gripper bar plays a crucial role in the feeding and positioning of the paper within the printing press. Its primary function is to grab and transport the paper from the paper feeder to the printing unit. As the printing press operates, the gripper bar moves in a synchronized motion, ensuring accurate alignment and smooth passage of the paper through the various printing components.
The metal fingers or grippers on the bar firmly grasp the paper along its edges, preventing any slippage or misalignment during the high-speed printing process. These grippers are designed to be adjustable, enabling them to accommodate different paper sizes and thicknesses.
In addition to its gripping function, the gripper bar also serves as a guide, helping to control the paper's movement as it gets fed into the printing unit and allowing precise registration of subsequent colors or images.
Overall, the gripper bar is an essential component of a printing press, ensuring the reliable and accurate feeding of paper during the printing process. Its design and functionality enable smooth operation and consistent print quality in the newspaper industry.
