Folder-gluer machines are specialized equipment used in the packaging industry to fold and glue cardboard boxes and other paper products. These machines automate the process, increasing efficiency and ensuring consistent quality in the production of packaging materials. They can handle various sizes and styles of boxes, making them versatile for different applications. Typically, a folder-gluer machine operates by feeding flat sheets of cardboard into the machine, where they are folded into shape and glued at the seams. This process is essential for creating ready-to-assemble boxes used in shipping and retail, streamlining the packaging workflow for manufacturers.
