Material discharge head of material discharge device comprises material discharge surface comprising material discharge openings, and connecting channel for direct connection to the material discharge opening with material storage container

摘要

Material discharge head (1) of a material discharge device for coating a substrate (2) with at least one material (9), which is discharged above the discharge head, comprises (a) at least one material discharge surface (4) comprising many material discharge openings (5), and (b) a connecting channel for optionally direct connection to the material discharge openings with at least one material storage container of the material discharge device. The material discharge surface is aligned to the substrate, which is to be coated. Independent claims are also included for: (1) the material discharge device comprising the material discharge head; and (2) coating the substrate with at least one material, comprising discharging at least one material from the material discharge head to the substrate.
