PROBLEM TO BE SOLVED: To provide a feeding device which intermittently feeds a strip-shaped blank and which has no reciprocating drive servo motor. SOLUTION: An adjustment nut 57 is disposed on a screw spindle 5, and the adjustment nut supports a first double arm lever unit 93 having a first arm 94 and a second arm 95. A second double arm lever unit 103 is assembled with the second arm of the first double arm lever unit via a connection strip 101 turnably by a first arm 102, and the second arm 104 of the second double arm unit is turnably assembled with a rocker 33 via control rod units 68 to 75. The rocker cooperates with a lower feed roller 22 to feed a strip-shaped blank 7, and supports an upper feed roller 10. The first arm 96 of the first double arm unit supports a bolt 58 protruded into a slotted hole 59 of the eccentrically supported rod 96. COPYRIGHT: (C)2004,JPO |
