Abstract
A manufacturing method for a carbon heat source comprises: a step A1 of forming a first groove in a state where the plurality of carbon members are aligned in one line; a step A2 of changing, subsequent to the step A1 being performed, an orientation of the plurality of carbon members so that the first groove formed in the plurality of carbon members crosses relative to the first predetermined direction in a state where the plurality of carbon members are aligned in one line; and a step A3 of forming, subsequent to the step A2 being performed, a second groove in a state where the plurality of carbon members are aligned in one line.
Claims8
A manufacturing method for a heat source made of carbon, the method comprises the following steps:
- providing a plurality of carbon members, each said carbon members having a pillar-like profile with an ignition end formed at a proximal end and a non-ignition end formed at a distal end;
- a step A including:
- step A1—conveying in a first predetermined direction along transport belts, the plurality of carbon members with the ignition end projecting upwardly wherein the plurality of carbon members are aligned in one line along the first predetermined direction,
- forming a first groove in the ignition end of each of the plurality of carbon members, said first groove extending along the first predetermined direction in each of the plurality of carbon members and said first groove extending in a longitudinal axis direction from the ignition end towards the non-ignition end of each of the plurality of carbon members,
- transporting the plurality of carbon members along the first predetermined direction;
- step A2—changing, subsequent to the step A1 being performed, an orientation of the plurality of carbon members by using transport belts so that the first groove formed in each of the plurality of carbon members is at a predetermined angle relative to the first predetermined direction in a state where each of the plurality of carbon members is aligned in one line while transporting the plurality of carbon members;
- and
- step A3—forming, subsequent to the step A2 being performed, a second groove crossing the first groove along a second predetermined direction in each of the plurality of carbon members, said second groove extending in the longitudinal axis direction from the ignition end towards the non-ignition end of each of the plurality of carbon members, wherein the plurality of carbon members are aligned in one line along the second predetermined direction while using transport belts for transporting the plurality of carbon members along the second predetermined direction.
