Abstract

Punch member 10 punches parts 12 out of a continuously fed strip of metal 14 that moves in direction 16 as shown in A. Parts 12 are stacked in holder 18. It is desirable to provide a separator 20 between predetermined numbers of parts 12. Provided for this purpose is a strip 22 of a relatively hard, yet flexible material, such as TEFLON*, which is fed in direction 24.

Punch Press

Punch member 10 punches parts 12 out of a continuously fed strip of metal 14 that moves in direction 16 as shown in A. Parts 12 are stacked in holder 18. It is desirable to provide a separator 20 between predetermined numbers of parts
12. Provided for this purpose is a strip 22 of a relatively hard, yet flexible material, such as TEFLON*, which is fed in direction 24.

A counter, not shown, is set to actuate solenoid 26 when a predetermined number of parts 12 is located in holder 18. Solenoid 26 pushes carrier 28 from position 30 under stripper 32 to position 34. Punch member 10 punches both another part 12 and a separator 20. Carrier 28 then retracts without punch member 10 missing a stroke and strip 22 advances. Carrier 28 is cut away at 34 to accommodate punch member 10.

The advantage of the arrangement includes an automatically provided separator 20 that eliminates stoppage of the press. Wear on the press clutch and break mechanism is minimized. The press operates much faster than during hand insertion of separators. *Trademark of E. I. du Pont de Nemours and Co.
