Sheet punching and embossing machine i.e. flat bed sheet punching and embossing machine, operating method for machining sheet of e.g. paper, involves passing gripper bars through curved rail lines with specific speed profile

摘要

The method involves providing a feeder (1), working stations e.g. punching station (2) and stripping station (3), and a sheet conveying system (7). Gripper bars (8) of the sheet conveying system are rotated in a closed rail line. Sheets (6) are held by grippers of the gripper bars. The gripper bars are operated by an electrical linear drive. The closed rail line is formed by straight rail lines and curved rail lines. The gripper bars are passed through the curved rail lines with a specific speed profile.
