Abstract
An apparatus for precisely cutting lengths of strip material includes a supply of strip material, a feed mechanism for conveying the strip material from the supply and a reciprocating cutter mounted downstream of the feed mechanism. An adjustable stop is movably mounted adjacent the cutter for engaging an end of the strip material and setting a precise length of the strip material being cut. An adjustment mechanism is coupled to the stop for moving the stop relative to the cutter along a longitudinal axis of the length of the strip material being cut.
Claims58
An apparatus for precisely cutting lengths of strip material, comprising:
- a supply of magnetizable strip material;
- feed means for conveying said strip material from said supply;
- a vertically reciprocating cutter mounted downstream of said feed means, said cutter having a cutting edge;
- a cutter actuator coupled to said cutter to move and push said cutter against and through said strip material, said cutter actuator including a rotating cam that engages an end of said cutter remote from said cutting edge of said cutter;
- an adjustable stop, movably mounted adjacent said cutter, for engaging an end of said strip material and setting a precise length of said strip material being cut;
- adjustment means, coupled to said stop, for moving said stop relative to said cutter along a longitudinal axis of the length of said strip material being cut, said adjustment means including a rotatably mounted rod with a fine pitch screw thread and an electric stepper motor connected to and controlling rotations of said rod, said stop threadedly engaging said rod;
- a stationary, magnetized strip holder positioned adjacent said cutter and extending between said feed means and said stop;
- at least one vertically reciprocating ejector pin positioned adjacent said strip holder;
- and
- an ejector pin actuator coupled to said ejector pin and actuating said ejector pin to move and push said strip material from said strip holder after cutting, said pin actuator including a rotating cam that pushes said ejector pin against said material strip.
