ABSTRACT:
A sealing device with flexible seals, for chromium-plating of bars and the like, in which each seal has a central aperture for the passage of the bars, defined by flexible fins delimited by slits directed substantially in a radial direction, starting from the inner edge of the central aperture; each seal moreover is composed of two sheets of soft plastic material welded together and enclosing steel springs to stiffen the fins. The sealing device preferably comprises a combination of at least two coupled seals, in which the sealing fins of one of the seals overlap corresponding slits between adjacent fins in the other seal.
