NOZZLE FOR FORMING SLANTING WAVY PATTERN OF VISCOUS FLUID MATERIAL, METHOD OF APPLYING VISCOUS FLUID MATERIAL TO SUBSTRATE MATERIAL, AND PRODUCT

摘要

PROBLEM TO BE SOLVED: To provide a nozzle capable of forming neighboring patterns closely and preventing dripping of a viscous fluid material. SOLUTION: A nozzle (40) for forming approximately slanting wavy patterns of a viscous fluid material is provided with projections (46) slanting at a prescribed angle to the moving direction relatively to a substrate and arranged longitudinally, orifices (48) provided in the projections and for forming substantially continuous fibers of the viscous fluid material by discharging the viscous fluid material, and at least two gas holes (56) provided respectively in vicinities of both walls (46a) extending longitudinally in the projections (46) and for jetting a gas to the fibers of the viscous fluid material to vibrate the viscous fluid material in the direction approximately vertical to the longitudinal direction in the case the nozzle is attached to a coating material.
