Abstract
A filter rod making machine wherein successive increments of a stream constituting a converted tow of filamentary filter material for tobacco smoke are contacted by a compressing tool which is vibrated at a frequency and/or amplitude sufficient to prevent over-heating of the tool and/or of filaments of filter material, such as acetate fibers. Conversion of the tow into the stream and the wrapping of the compressed stream into a running web of filter paper are carried out in a conventional manner.
