Abstract
Rods for use in the manufacture of smoking products are provided using a rod-making apparatus. The apparatus includes (a) an unwind unit for continuously supplying a material having a continuous integrity; (b) a rod-forming unit for forming a rod-like composite of the supplied material; (c) a constriction member for constricting the rod-like composite, the constriction member including (i) a material-contacting surface and (ii) a reservoir for supplying an amount of liquid to at least a portion of the material-contacting surface; and (d) a rod-making unit for receiving the rod-like composite and for circumscribing the rod-like composite with wrapping material thereby forming a continuous rod.
Claims18
An apparatus for manufacturing rods for use in the manufacture of smoking articles, the apparatus including:
- (a) means for continuously supplying a material having a continuous integrity;
- (b) means for forming a rod-like composite from the material;
- (c) means for constricting the rod-like composite, said means including (i) a material-contacting surface and (ii) means for supplying an amount of liquid to at least a portion of the contacting surface through at least one liquid outlet opening in the contacting surface and
- (d) rod-making means for receiving the rod-like composite with wrapping material thereby forming a continuous rod.
A method of manufacturing rods for use in the manufacture of smoking articles, the method comprising:
- (a) continuously supplying a material having a continuous integrity;
- (b) forming a rod-like composite from the supplied material;
- (c) constricting the rod-like composite by contacting the material with a material-contacting surface;
- (d) supplying amount of liquid to at least a portion of the material-contacting surface through at least one liquid outlet opening in the contacting surface and
- (e) forming a continuous rod from the rod-like composite by circumscribing the rod-like composite with wrapping material.
An apparatus for manufacturing rods for use in the manufacture of smoking articles, the apparatus including:
- (a) means for continuously supplying a material having a continuous integrity;
- (b) means for forming rod-like composite from the material;
- (c) means for constricting the rod-like composite, said means including (i) a material-contacting surface and (ii) means for supplying a liquid directly to at least a portion of the contacting surface through at least one liquid outlet opening in the contacting surface, said opening positioned so as to permit the supplied liquid to reduce the build-up of friction between the contacting surface and the material having a continuous integrity, and (iii) at least one groove along the longitude of the matrail-contacting surface thereof;
- and
- (d) rod-making means for receiving the rod-like composite with wrapping material thereby forming a continuous rod.
