Provided are a method a for manufacturing metallic cans and resulting structure apparatus, where the method provides a continuous manufacturing process carried out instead of individually carrying out separate processing, thereby preventing the provision of any additional equipment and improving the efficiency in the manufacturing of metallic cans. A method for manufacturing metallic cans can be realized by simultaneously carrying out the sealing lip processing and the curling part processing by a press method, thereby simplifying the manufacturing facilities, manufacturing procedure or the like.

Disclosed is a method and a tag feeder for feeding tags in a feeding direction to a dispensing position within a clipping machine. The tag feeder is provided with a feeding mechanism with at least one pusher means for transporting a chain of tags. The pusher means is reversible movable parallel to the feeding direction between a first and second position wherein, in the first position, the pusher means is in a minimum displacement to the dispensing position, and wherein, in the second position, the pusher means are in a maximum displacement to the dispensing position. The feeding mechanism comprises at least one cutting tool for cutting-off the foremost tag of the chain of tags, viewed in the feeding direction, in the first position and at least one clamping device for clamping the chain of tags when the foremost tag is arranged in the first position.

There is provided a machining apparatus in which movement of a machining point is a little, restriction on the machining operation of an articulated robot is a little and movement of a worker for the teaching operation is a little. The machining apparatus has an articulated robot which is controlled in attitude according to a teaching operation and has a catch instrument for catching a workpiece at an arm tip thereof, and a machining unit equipped at a fixed portion located within an arm reachable zone of the articulated robot, wherein the machining unit has a working tool having a profiling portion where a machining target portion of the workpiece caught by the catch instrument of the articulated robot is pressed according to the attitude control of the articular robot, and a floating mechanism that pushes the working tool in a press direction of the workpiece.

An apparatus to cut and surface process a workpiece includes a cutting tool to cut the workpiece; a peening tool to peen surfaces of the cut workpiece; and a controller to control the cutting tool, the peening tool and the workpiece to move simultaneously.
