A cutting device and a cutting method, comprising: a blade receiving portion crossing a cord-embedded rubber sheet member is disposed in one surface side in a thickness direction of the rubber sheet member placed in a conveying mechanism. A cutting blade disposed in the other surface side is held by a holder that rotates about a turning shaft extending in the thickness direction of the rubber sheet member. In a state in which a cutting-edge advancement direction turns about the turning shaft, a turning restoring force that restores the cutting-edge advancement direction to a preset moving direction is constantly applied by a turning restoring mechanism to the cutting blade before cutting the rubber sheet member. The rubber sheet member is sandwiched in the thickness direction by the cutting blade and the blade receiving portion, and the cutting blade is moved in the extension direction of cords.

A belt forming system may include an upstream conveyor, a downstream conveyor located downstream of the upstream conveyor, and a belt assembly system in communication with the upstream conveyor and the downstream conveyor. The belt assembly system may also include an arm, an actuator for moving the arm, and/or a holding component coupled to the arm and adapted to move a strip section from the upstream conveyor to a desired position on the downstream conveyor such that the strip section is oriented at a predetermined angle on the downstream conveyor. In one embodiment, the belt forming system comprises a belt cutter. The present disclosure also relates to a method for manufacturing at least a portion of a tire belt.
