# Dross transportation conveyor, laser beam machine apparatus, and workpiece machining method

## Abstract

A dross transportation conveyor includes a group of transportation plates configured to transport dross generated by irradiation of a laser beam on a workpiece. The group of transportation plates includes a first transportation plate extending in a first direction and a second transportation plate extending in the first direction and disposed to be adjacent to the first transportation plate. The first transportation plate includes a first front end portion, a first rear end portion, and a first middle portion connecting the first front end portion with the first rear end portion and having a first concave portion that extends in the first direction.
