Abstract:

To provide a method for producing a tobacco filter improved in molding speed without causing crash on a hollow part formed by groove-cutting parts when rolling up the periphery of the filter so as to be wrapped with a grooved tape when the tobacco filters are bundled together.

The method for producing a tobacco filter comprises the following process: opening filter raw material 3 for a core part with a filter plug machine 4 followed by rolling up the material so as to wrap the outer periphery thereof with a grooved tape 6 obtained by subjecting a paper tape 1 having stretchability in a width direction of 14-20% and ≥3 kN/m of tensile strength in a longitudinal direction when bundling the opened material into a round rod shape; and rolling up the whole of the material with a paper web 8.
