Air-steam interface in continuous vulcanization process for allowing accurate optical measurements

摘要

A novel process and apparatus are disclosed which permit an air-stream interface to be maintained in a continuous vulcanization cable production process in order to enable accurate optical measurements of the cable to be taken at all times. Specifically, a baffle assembly is provided in conjunction with a high pressure, high temperature steam supply and a high pressure air supply to maintain a clear air region in a steam vulcanization chamber. The baffle assembly together with interconnected air and steam supply lines and an exhaust line provides a flow pattern which permits an optical window within the clear air region to be maintained in a clear and unobstructed state so that optical measurements can be continuously conducted while the vulcanization process is in operation.
