Abstract:
1. An apparatus for processing elongate material continuously advancing along a processing path, comprising: at least a first pair of cyclically driven tools following an orbital movement, between which the material passes as it moves along the processing path, and which synchronously engage opposite faces of the material during a portion of the orbital movement and move at the same linear speed as the material when in contact therewith, and return upstream along the orbital movement to re-engage the advancing material and repeat the processing cycle, wherein each tool is cantilevered on a near end transversely of the processing path from a tool drive located adjacent a near edge of the processing path and further wherein the tool drive for each tool supports the tool for orbital movement around a drive axis that extends transversely of the processing path such that the orbital movement forms a circle; and a pair of passive devices effective during a portion of the orbital movement, each located near a distal end of one of the pair of tools, to affect the position of the distal end.
