  • Patent number: 6722020
    Abstract: A workpiece table assembly is configured to hold a plurality of workpieces (e.g. conductive strands) so that the workpieces can be modified (e.g. bent). In one embodiment, the workpiece table assembly advantageously comprises a table, a saddle, a lift mechanism, and a die. The saddle is advantageously recessed below the table and raised or lowered by the lift mechanism. The table advantageously has a top surface with holes adapted to accept quick-release pins from a step-off board. The step-off board also has notches to accept and position the strands for die pressing. In one exemplary operation, the step-off board is used to stagger the strands over the down-positioned saddle. The saddle is then raised by the lift mechanism and the die placed within the saddle on top of the strands. A force is applied to the die to bend the strands.
