Pipe painting process

摘要

A substrate coating method may include: translating the substrate in a first direction through a spray zone while spraying a fluid coating on a first uncoated surface portion to produce a first coated surface portion; heating at least the first coated surface portion to form a first cured coating while translating the substrate through the heating zone in the first direction and a second, opposite direction; manipulating a second uncoated surface portion in a position to be spray-coated; spraying the fluid coating onto the second uncoated surface portion while translating the substrate in the first direction through the spray zone to produce a second coated surface portion; and heating at least the second coated surface portion to form a second cured coating while translating the substrate in the first direction through the heating zone. The method may thereby provide the substrate with the first and second cured coatings.

1. A method for coating a substrate, comprising:
translating the substrate in a first direction through a spray zone, the substrate having a first uncoated surface portion; spraying a fluid coating onto the first uncoated surface portion of the substrate to produce a first coated surface portion of the substrate while translating the substrate in the first direction through the spray zone; heating at least the first coated surface portion to form a first cured coating of the substrate while:
translating the substrate in the first direction through a heating zone; andtranslating the substrate in a second direction substantially opposite the first direction through the heating zone; continuing to translate the substrate in the second direction through the spray zone; manipulating the substrate to place a second uncoated surface portion on the substrate in a position to be spray-coated; spraying the fluid coating onto the second uncoated surface portion of the substrate while translating the substrate in the first direction through the spray zone to produce a second coated surface portion of the substrate; and heating at least the second coated surface portion to form a second cured coating of the substrate while translating the substrate in the first direction through the heating zone, thereby providing the substrate with the first and second cured coatings.
