Some embodiments provide a novel method for forwarding a packet at a first managed interconnection switching element in a managed network of interconnection switching elements. The lumen body is joined to a lead body, and electrical connectors are longitudinally spaced along the lumen body. An opening is disposed between the first and second tubing sections. The base of one transport containers constitutes the cover of a transport container arranged beneath it. 7% or more is impregnated with a resin composition containing a rubber latex, and that the number of twist of the cord is 10 per meter or less. In order to engrave a closed loop with a single processing head it is proposed that the processing head is pivotable through a drive device about a longitudinal axis of the cylinder.
