Method and apparatus for reducing a transporting strain on elongated material passing through a treatment chamber

Abstract From the Canadian patent

The method and apparatus are for reducing a transporting strain on elongated material passing through a treatment chamber. The transport is accomplished by a flowing transport fluid which is applied to the elongated material through at least one, preferably several jet nozzles in the direction reversing stations. The fluid is applied in a direction substantially corresponding to the transport direction and passes around a guide surface where it forms a travelling cushion between the guide surface and the elongated material. The flow speed of the fluid corresponds at least to the transport speed or the inlet speed into the chamber. Each direction changing station includes a guide body having …
