  • Machine for processing elements in sheet form, comprising a chainset tensioner
    Patent number: 9061845
    Abstract: A machine for processing elements in sheet form, the machine having chainsets which move gripper bars for moving sheet elements through the machine. At least one tensioner device generates a tension force in the chainsets. The chainset tensioner device includes a drive member capable of generating a variable force, having an intensity dependent on the instantaneous production rate of the machine. Chainset wear is greatly reduced, and the life of the chainsets is lengthened considerably.
