Title:
ねじ付きファスナへフルオロポリマー被覆を塗布する方法及び装置
Document Type and Number:
Japanese Patent JP4114721
Kind Code:
B2
Abstract:
A process and apparatus are provided for the application of a fluoropolymer coating to the threads of an internally threaded fastener. The fastener is moved on a conveyor with its first opening closed by means of an obstructing member, while an air stream carrying entrained fluoropolymer powder is directed from a stationary nozzle through the second opening and into the threaded bore. After the fluoropolymer powder is deposited onto the threads of the fastener, the conveyor moves the fastener through a heating station where the fluoropolymer powder is raised to its melting temperature causing it to melt and fuse into a generally continuous film covering the fastener's threads.
