Abstract (en)
[origin: WO8200017A1] The instant workpiece holder eliminates the problem of loss of gripping force and detachment of the core from the holder. The workpiece holder (10) has a plurality of elements (38) movable radially outwardly into engagement with an inner surface of a workpiece (74) in response to movement of a cam (48) and includes at least one spring-actuated latch (56) which engages the cam (48) and prevents disengagement of the workpiece holder (10) from the workpiece (74) during operation of the workpiece holder.
