[Problem] To provide a conveyor and a conveying method that can suppress excessive rotation and insufficient rotation of a supply roll for intermittently feeding out cell material, even if the inertial moment of the supply roll changes. [Solution] A conveyor (100) comprising: a supply roll (110) on which is wound a belt-shaped cell material (W) that is a material for an electrode or a separator, the supply roll intermittently feeding out the cell material (W) by rotating; roll detection means (240) for detecting the amount of the cell material (W) remaining on the supply roll (110); and brake force applying means (230) for applying brake force to the rotation of the supply roll (110) based on the amount of the cell material (W) detected by the roll detection means (240). |
