摘要

In a cigarette manufacturing machine, a device for compressing and molding a filler stream (SF), includes a tongue (22) defining a part of a compression-molding passage. The filler stream (SF) passes the compression-molding passage. The device further includes an ultrasonic vibration system (30,32) for vibrating the tongue (22). The tongue (22) functions as a horn of the ultrasonic vibration system (30,32). <IMAGE>
