Patent ID: 7213384

Claim:
A device for the production of tubular bags filled with bulk goods from a continuous foil tube moving in a run direction comprising: at least a pair of tool mounts that follow an orbital movement, wherein the tool mounts have a near end and a distal end, and wherein the near end is linked to a device that imparts the orbital movement to the tool mounts; a first pair of opposing tools, each mounted on one of the pair of tool mounts, that cyclically engage the tube and seal the foil tube in bag-length intervals during a portion of the orbital movement; a second pair of opposing tools, each mounted on one of the pair of tool mounts, that remove bulk goods from the area of the seal by a wiping motion effective in the run direction, linked to follow a path responsive to the orbital path; and a pair of opposing passive devices, each mounted near the distal end of each tool mount effective during at least part of the portion of the orbital movement, wherein the passive device affects the path of a selected pair of the first and second pairs of tools mounted on a carrier such that the distal end of the selected pair follows a path parallel to a path the near end of the selected pair follows, wherein the pair of passive devices includes a tracer pin.
