Abstract
Disclosed is a coating die which has a dilatable orifice, the orifice being dilatable due to the use of a flexible, resilient portion of the die. The die is individually cast and is "strung-up" in the casting process. The preferred use for the die is in the coating of textile filaments, especially small diameter filaments that are slubby.
