ABSTRACT:
Apparatus for processing continuously fed elongate material, such as forming sealed bags from continuously fed film tubes, uses at least one pair of orbital tools that are cantilevered from tool drives (e.g., crank arms) at one edge of the material, extending transversely across the direction of material travel to engage opposite faces of the material. During material engagement the tools run synchronously with the moving material, but may be returned upstream rapidly to reengage the material for the next processing cycle. In order to achieve a higher throughput an additional pair of tools can be used, cantilevered and driven from the opposite edge of the material, maintaining the same processing (e.g., sealing) time. Through this arrangement the tools on opposing sides can alternate contact with the material and be run independently of each other.
