Workpiece supporting assembly for a table saw

摘要

A workpiece supporting assembly for a table saw includes a worktable and two horizontal rows of rollers disposed respectively and rotatably on two vertical side walls of the worktable. Two movable rails are disposed respectively on the side walls of the worktable. Each of the rails has an open-ended horizontal dovetail groove that extends long the length thereof and that confines the rollers of a corresponding one of the rows therein. A horizontal extension support plate rides on the rails. Accordingly, the rails and the extension support plate can move smoothly relative to the worktable.
