PURPOSE:To make the replacing work of a finger easy by equipping the medium member only with a finger with compising a feeding bar by three members of the front, medium and rear which are freely separatable and by making the medium member only being able to be taken out at the metal die exchanging time. CONSTITUTION:A feeding bar 1 is composed of three members of freely separatable front member 2, medium member 3 and rear member 4 and a finger 5 is equipped with only by the medium member 3. When the piston rod of a vertical binding fluid pressure cylinder is pushed out with moving the slide which links the feeding bar 1 upto the position of some this side of 1/2 of the total stroke, the backward arm of a bell crank lever 7 is turned upward with separating from a cam. It is stopped when the rise thereof reaches the 1/2 position of the total stroke by the revolution of the cam. A carrier 6 is therefore advanced upto the position of 1/2 of the total stroke and the feeding bar 1 can take out the medium member at the middle position between the advancing end and backing end and the replacement of the finger 5 can be easily performed. |
