摘要： Methods and apparatus for applying a plastic coating to woven yarn tubing to provide conduit for protecting wiring harnesses and the like. The resulting plastic coating layer is very thin so as to generally follow the contours of the woven yarn tubing, without filling in the valleys, thus minimizing the amount of plastic used. Woven yarn tubing is waterproofed by impregnating with latex sealant, and is continuously pulled by a take-up mechanism along a horizontal axis through a heated die and two treating stations in tandem. Each of the treating stations includes a coating pot containing liquid plastisol material and having a resilient circular exit die through which the tubing exits the coating pot to form a layer of liquid plastisol, and an infrared curing oven which heats the plastisol-coated tubing sufficiently to cure the plastisol layer. The tubing, while coated with uncured plastisol material, is not contacted by any element which would tend to deform the tubing from a circular cross section.
