ABSTRACT:
A running tow of spread-out filamentary filter material in a filter rod making machine is sprayed with plasticizer by two ultrasonic atomizing devices which are disposed at the opposite sides of the path of the tow and each of which has a flexural resonator connected to one or more piezoelectric elements which, in turn, are connected to a source of a-c potential in order to expand and contract when the atomizing devices are in use. Each flexural resonator has an atomizing surface which extends transversely of the path for the tow, and the system which supplies plasticizer to such surfaces has pipes discharging plasticizer in the region of some or all oscillation nodes which develop when the atomizing devices are in use.
