Ultrasonic surface transducer for textile finishing, textile finishing devices and textile finishing processes

摘要

An ultrasonic surface oscillator (1) for textile finishing is proposed, comprising a converter system, which converter system is designed to generate an excitation oscillation, and at least one ultrasonic oscillating element (6), which ultrasonic oscillating element (6) has a connection surface (7) and has an effective surface, which connection surface (7) is designed and provided to absorb the excitation vibration from the converter system and which effective surface is designed and provided to couple an effective vibration into a textile-finishing liquid. The connection surface (7) comprises at least two partial connection surfaces (7 ', 7' ', 7' '') and the converter system comprises at least two separate ultrasonic single transducers (8 ', 8' ', 8' ''), with a given ultrasonic Individual oscillators (8 ', 8' ', 8' '') each with a partial connection surface (7 ', 7' ', 7' '') is mechanically coupled and a total area of all partial connection surfaces (7 ', 7' ', 7' ' ') is smaller than the effective area.
