Gripper bars & gripper bar chain system

BOBST Original gripper bars play an essential role in transporting sheets and boards in Autoplatine^® presses. Each bar is painstakingly designed, developed and tested by our engineers to guarantee perfect transport of sheets. Produced according to demanding and rigorously controlled criteria, gripper bars are subject to many stresses, particularly as a result of the high inertia of moving parts.

Gripper bar design has evolved over the years. New technical solutions have been developed, improving the mechanical concept and reinforcing sheet grip. This helps to maintain precise and steady sheet transfer through the cutting, stripping and delivery stations on BOBST machines.

BOBST Original gripper bar chains (chains and links) are specially designed to withstand sharp accelerations and keep the gripper bars in a perfect position throughout the production process. Preassembled and with links tested for their endurance, they help to minimize downtime by making installation and replacement easier.

Chain guides and their components complete the system, holding the chain in place, ensuring smooth rotation and minimizing wear. They guarantee precise guiding, which reduces the risk of blockages, thus contributing to continuous and efficient production.

Together, these components guarantee the stability, precision and durability of cutting and converting operations on BOBST Autoplatine^® presses, thus supporting optimum performance of your production processes.
