  • Device for changing stacks continuously operated sheet feeding machines
    Patent number: 3951401
    Abstract: A fork-like stack changing table arranged to support a residual stack and to be withdrawn when the next stack is raised to it. Sealing strips seal the space between the stacks and the fork rods and means are provided for applying compressed air to the space between stacks. In this way, the residual stack bears lightly upon the auxiliary table and it can be withdrawn permitting the main stack to join the residual stack.
