1. A double stroke - double blow header including a frame in which a continuous length of wire material is fed through an opening of a stationary cutter mounted in the frame into an opening of a movable cutter in which a pin is slidably received when the movable cutter is in axial alignment with said stationary cutter, means for moving said movable cutter from its axially aligning position with said stationary cutter to another position in which the movable cutter is in axial alignment with and opposing relation to a forming die fixedly secured to said frame while shearing the portion of the material within said opening of the movable cutter from the remaining portion of the material within said opening of the stationary cutter, a drive shaft supported in the frame, a slide mounted on said frame, said slide having a forming punch attached thereto and a linkage mechanism operably connecting the drive shaft and slide including means whereby the slide is advanced in a shorter distance stroke so that said sheared material portion within said opening of the movable cutter will be driven into said forming die by said forming punch via said pin and simultaneously will be delivered a preliminary forming blow thereagainst by the forming punch via said pin so as to partially form the material portion to an intermediate product, said movable cutter being moved back from the position in which the cutter is in axial alignment with the forming die to the original position in which the cutter is in axial alignment with the stationary cutter and finally, said slide being advanced in a longer distance stroke so that the partially formed intermediate product will be delivered a final forming blow by said forming punch to form a final desired product.

2. A double stroke - double blow header comprising a machine frame; a slide supported in said machine frame for reciprocal movement in linear shorter and longer distance strokes; a punch attached to said slide for movement with the slide; a forming die fixedly secured to said machine frame in axial alignment with and in opposing relation to said punch; said die having a forming cavity for receiving a product ejecting knockout pin therein; a stationary cutter fixedly secured to said machine frame and having an opening extending axially therethrough and through which axial opening a continuous length of wire materiaL is to be fed; a movable cutter having an axial opening for receiving said wire material and also for loosely receiving an axial displaceable pin therein and movable between a first position in which said movable cutter is in axial alignment with and in opposing relation to said stationary cutter and a second position in which the movable cutter is in axial alignment with and opposing relation to said forming die; a drive shaft rotatably supported in said machine frame and having an integral eccentric sheave thereon; a rockable slide drive lever loosely fitted on said eccentric sheave on the drive shaft and having one end pivoted to said slide through a linkage; a follower shaft rotatably supported in said machine frame to be driven from said drive shaft with a rotational speed ratio of 2:1 with respect to the drive shaft, said follower shaft having two eccentric sheaves integrally formed therewith; a control lever loosely fitted on one of said eccentric sheaves on the follower shaft and connected to the other end of said slide drive lever by means of a pin; and an actuating bar loosely fitted on the other eccentric sheave on the follower shaft for actuating said product ejecting knockout pin so as to cause the knockout pin to eject a product out of said forming cavity of said die.
