SPOUT COATING METHOD FOR HOT MELT BONDING AGENT, ATTACHMENT FOR PATTERN AIR NOZZLE, AND SPOUT COATING BONDED PRODUCT

摘要

PURPOSE:To prevent a fiber from highly crowding by spraying air to spiral beads from sideway and deforming a conical spiral shape into a non-conical shape. CONSTITUTION:Hot melt is discharged while spinning spirally from a spiral shape discharging nozzle 1 for beads. Simultaneously, pattern air is sprayed from both sides to press ring Fis of spiral beads to bedeformed into elliptical Fie. The same are lowered by approximately 20cm in said state to reach the surface of a material W to be discharged, while beads HBs are stretched to turn into elliptical ring of fiber and to be accumulated thereon during the process. When the material W to be discharged is moved in the short axis direction of elliptical ring Fie, a discharge coating belt Pec of continuous elliptical ring of fiber is formed. The thickness of a discharge coated layer is uniformized by said arrangement and continuous pattern can be discharged coated.
