Method and machine for making a filter rod |
摘要 |
The mass of successive increments of a wrapped rod-like filler of filamentary filter material is monitored by a beta ray detector and the signals which are generated by the ionization chamber of the dectector are utilized to adjust the ratio of a variable-speed transmission which regulates the rate of delivery of a stretched tow of filamentary material to the gathering horn of a filter rod making machine.
