ABSTRACT:
A work table for use in connection with a sheet metal brake is mounted on the frame of the sheet metal brake for swinging movement between a first position, where the table extends over the clamp of the brake to provide a convenient work surface for the preparation of a sheet of metal to be bent in the brake, and a second position, where the table is swung away from the clamp to enable access to the clamp for subsequent bending of the prepared sheet of metal, and is arranged to be biased by gravity into selective retention at either of the first and second positions.
