Abstract
A manufacturing machine for rod-shaped articles comprises a wrapping section (4) for forming a rod-shaped article by wrapping a filler material in a wrapper. The wrapping section has a forming bed (6) for guiding a garniture tape (10), which is used to form the rod-shaped article, in travel. The manufacturing machine further comprises a cooling system for cooling the forming bed (10). The cooling system is provided with cooling passages (43, 45, 47, 49, 143, 145, 149) formed in portions 6A to 6D of the forming bed (6) and a circuit for supplying a coolant to the cooling passages.
Claims14
A manufacturing machine for rod-shaped articles comprises:
- a wrapping section supplied with a filler material and a wrapper and capable of forming a rod-shaped article by wrapping the filler material in the wrapper, said wrapping section including an endless tape, used to form the rod-shaped article and capable of running the wrapper together with the filler material in one direction, and a forming bed for guiding the endless tape in travel;
- and
- cooling means for cooling said wrapping section, said cooling means including a cooling passage formed at least in said forming bed and a circuit for circulating in and supplying a cooling medium to said cooling passage,
- wherein a forming bed of said wrapping section is divided into a plurality of regions adjoining one another in the traveling direction of the wrapper, and said cooling means includes a plurality of cooling passages formed independently in the regions,
- wherein said forming bed of said wrapping section is formed with an upper portion and a lower portion, said lower portion being divided into a plurality of individual regions adjoining one another in the traveling direction of the wrapper, said regions having grooves, which in conjunction with said upper portion form independent cooling passages in said forming bed.
A manufacturing machine for rod-shaped articles comprises:
- a wrapping section supplied with a filler material and a wrapper and capable of forming a rod-shaped article by wrapping the filler material in the wrapper, said wrapping section including an endless tape, used to form the rod-shaped article and capable of running the wrapper together with the filler material in one direction, and a forming bed for guiding the endless tape in travel;
- and
- cooling means for cooling said wrapping section, said cooling means including a cooling passage formed at least in said forming bed and a circuit for circulating in and supplying a cooling medium to said cooling passage,
- wherein a forming bed of said wrapping section is divided into a plurality of regions adjoining one another in the traveling direction of the wrapper, and said cooling means includes a plurality of cooling passages formed independently in the regions, and
- wherein said wrapping section further includes an upper wrapping section located over said forming bed, said upper wrapping section having a compression mold capable of defining a compression molding passage for the filler material in cooperation with said forming bed, a first mold located on a lower-stream side of said compression mold as viewed in the traveling direction of the wrapper and capable of curving one side edge of the wrapper in a circular arc to cover the filler material, and a second mold located on the lower-stream side of said first mold as viewed in the traveling direction of the wrapper and capable of curving the other side edge of the wrapper in a circular arc to cover the filler material;
- and said cooling means further includes a cooling passage formed at least in said compression mold, out of said molds, said cooling passage being supplied with the cooling medium from said circuit.
