Abstract: A work holding apparatus, which can be set up at low cost, for an assembly configured by stacking a plurality of components. A holding apparatus includes plurality of cylindrical collets arranged in a row; a plurality of cylindrical pieces arranged between the collets; and a pressurizing apparatus, which is inserted into the collets and the pieces and applies pressure to sandwich the collets and the pieces from the both end sides. The outer diameter of the piece is larger than the inner diameter of the collet at the center, becomes smaller toward the both ends from the center, and is smaller than the inner diameter of the collet at the both ends.

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.
