Abstract

A tip paper cutting apparatus for a filter cigarette manufacturing system includes a pair of brush rollers arranged close to a bladed drum, and a brush is mounted on the outer peripheral surface of each brush roller so as to be in contact with cutting blades of the bladed drum. Olive oil is atomized by compressed air in a spraying device, and supplied to passages formed within the brush rollers. Olive oil is then sprayed toward the brushes from spray ports of the passages opening in the outer peripheral surfaces of the brush rollers so as to pass through the brushes. Accordingly, even when the brush rollers are rotating at high speed, the brushes can be sufficiently soaked with olive oil passing therethrough. As a result, the cutting blades are reliably applied with olive oil by means of the brushes, and good cutting quality of the blades can be maintained.

A tip paper cutting apparatus for a filter cigarette manufacturing system, in which tip paper fed in between a receiving drum and a bladed drum is cut into pieces by cutting blades arranged on an outer peripheral surface of the bladed drum, the tip paper cutting apparatus comprising brush roller means which include:

a brush roller rotatably arranged close to the bladed drum and having an outer peripheral surface and a longitudinal axis, the brush roller having a first axial hole formed therein extending along the longitudinal axis of the brush roller, a plurality of discharge holes being formed in the brush roller, each of the discharge holes having a discharge port opening in the outer peripheral surface of the brush roller, the discharge holes each having a discharge axis which is nonparallel to the longitudinal axis of the brush roller;
a brush mounted on the outer peripheral surface of the brush roller;
a roller shaft fitted into the first axial hole of the brush roller, the roller shaft having a longitudinal axis and having a second axial hole formed therein extending along the longitudinal axis of the roller shaft, the roller shaft having at least one communication hole having a discharge axis extending in a radial direction of the roller shaft;
the discharge axis of each of the discharge holes being nonaligned and offset from the discharge axis of the at least one communication hole;
an annular space formed between the brush roller and the roller shaft, the at least one communication hole and the discharge holes being in communication with the annular space, the annular space extending along the longitudinal axes of the brush roller;
and
a passage formed in the brush roller means for receiving a paste repellent liquid, the passage including the plurality of discharge ports and discharge holes in the brush roller, the annular space, the at least one communication hole of the roller shaft and the second axial hole whereby paste repellent liquid can flow through the second axial hole of the roller shaft, through the at least one communication hole, through the annular space, through the plurality of discharge holes and then out of the discharge ports to the brush.
