CURING OF ULTRAVIOLET-CURING RESIN APPLIED TO WIRE

摘要

PURPOSE:To obtain a resin coat, characteristic of longitudinal uniformity by allowing inert gas to flow in the form of a laminar flow when wire coated with ultraviolet-curing resin is passed through a quartz tube and the resin is cured by irradiation with an ultraviolet beam while inert gas is introduced into the quartz tube. CONSTITUTION:Wire 10 coated with ultraviolet-curing resin is passed through a quartz tube 20, and the ultraviolet curing resin is cured by irradiation with an ultraviolet beam from an irradiator 18 through the quartz tube 20 while inert gas is introduced into the quartz tube from a supply means 28. At that time, the inert gas is allowed to run as a laminar flow. Consequently, a ultraviolet-curing resin coat which is characteristic of longitudinal uniformity can be manufactured with high workability.
