Claims
- 1. A blank forming apparatus comprising, a cylinder, a pair of mounting bars, and a flexible die, said die including a plurality of apertures and said cylinder including a support segment upon which the die rests, said support segment being bounded in the circumferential direction by a pair of longitudinally extending grooves, with one of the mounting bars mounted within each said groove,
- said apparatus further comprising a plurality of mounting pins extending outwardly in a radial direction from each bar, said plurality of pins being spaced from one another in the longitudinal direction of the respective bar and in the longitudinal direction of said cylinder, each pin having a shaft which extends through a corresponding aperture in said die and a head for passage through said corresponding aperture, said shaft having a first end connected to said bar, and said head positioned on said shaft and spaced from said first end.
- 2. The blank forming apparatus of claim 1, further including means for securing said bar to said cylinder within a range of positions within said groove, said range of positions including a longitudinal range and an angular range, with respect to said cylinder.
- 3. The blank forming apparatus of claim 2, wherein each groove includes at least one rotatably mounted cylindrical cam extending radially therefrom, and each bar includes a slot, elongated in the longitudinal direction, which receives said cylindrical cam, whereby rotation of said cylindrical cam causes angular movement of said bar with respect to said cylinder as said cylindrical cam engages said slot.
- 4. The blank forming apparatus of claim 3, wherein said cylindrical cam comprises a sleeve having a longitudinal axis and a bolt extending through said sleeve along an axis offset from said longitudinal axis of said sleeve, said bolt rotatable connected to said cylinder but fixed with respect to said sleeve, whereby rotation of said bolt causes rotation of said sleeve.
- 5. The blank forming apparatus of claim 2, wherein said means for securing comprises at least one elongate slot located in said bar, and a bolt extending through said slot and engaging said support segment.
- 6. The blank forming apparatus of claim 1, further including means for biasing said bar radially outward from said cylinder.
- 7. The blank forming apparatus of claim 6, wherein said means for biasing includes at least one spring extending outwardly from a bottom surface of said bar for positioning against said support segment.
- 8. A blank forming apparatus comprising a flexible die, a mounting bar and a cylinder, said flexible die having a plurality of apertures therein, said die positioned on an outer surface of a support segment of said cylinder, said bar attached to said cylinder within a groove in said cylinder, said apparatus further including a plurality of pins extending radially outwardly from an outer surface of said bar and through said apertures in said die, and further including means for adjustably positioning said bar on said cylinder in said groove.
- 9. The blank forming apparatus of claim 8, wherein at least one elongate slot is located in said bar and a bolt extends through said slot and engages said cylinder.
- 10. The blank forming apparatus of claim 8, further including means for biasing said bar upwardly out of said groove.
- 11. The blank forming apparatus of claim 10, wherein said means for biasing comprises at least one spring.
- 12. The blank forming apparatus of claim 11, wherein said spring is mounted on a pin connected to said bar.
- 13. The blank forming apparatus of claim 8, wherein said means for adjustably positioning comprises at least one cylindrical cam rotatably connected to said cylinder and extending through a slot in said bar.
- 14. The blank forming apparatus of claim 8, wherein said pins each comprise a shaft having a first end connected to said bar and a second end having an enlarged head.
