ABSTRACT:
Method of and apparatus for the manipulation of workpieces particularly in continuous travel, such as the introduction of a workpiece into a seat in an object. The invention utilizes a vehicle formed of an outer body in the interior of which there is disposed a tubular lining which is guided for longitudinal movement with respect to the body, the lining being adapted to receive a workpiece therewithin. The workpiece is introduced into the seat in the object while maintaining the object with its longitudinal axis coincident with the axis of the body of the vehicle by thrusting the object within the body of the vehicle so as to displace the lining of the vehicle from such body and until the seat in the object receives the worked piece. There is thus assured a relative centering of the workpiece with respect to the seat in the object and, in avoiding the movement of the workpiece one avoids problems of achieving alignment between the seat in the object and the workpiece while the apparatus is working at high speed in continuous motion. The invention finds one of its most important fields of application in the applying of percussion caps to the cartridge cases for ammunition.
