The bending bar is supported from below the worktable to move upwards in an arc about the bending edge of the anvil and the front edge of the hold-down bar, by parallelogram hinges housed within the frame legs and pivotal about points below and to the rear of the bending edge. The hold-down bar is supported on overhead cantilever arms extending forward from pivots on the rear of the machine frame. |
