Claims
- 1. In an apparatus for manufacturing pressware containers from container blanks having a lower die member for receiving said container blanks, an improved blank stop system comprising at least four rotatably mounted inertial blank stop pins disposed on the forward portion of the said lower die member and projecting upwardly therefrom,
at least two of said rotatably mounted inertial blank stop pins being outer pins located on said forward portion of said lower die member in opposing relationship to each other at a distance from each other which is less than the maximum transverse dimension of said container blank and which is greater than or equal to the maximum transverse dimension of the formed container, at least two of said rotatably mounted inertial blank stop pins being inner pins located on said forward portion of said lower die member, forwardly and inwardly located with respect to said outer pins, said inner pins being disposed in opposing relationship at a distance which is less than the maximum transverse dimension of the container formed from said container blank.
- 2. The improved blank stop system according to claim 1, wherein said outer pins project upwardly a greater distance than said inner pins.
- 3. The improved blank stop system according to claim 2, wherein said outer pins project upwardly at a height of from about {fraction (1/2)} to about 1½ inches and said inner pins project upwardly at a height of from about {fraction (1/8)} to about 1 inch.
- 4. The improved blank stop system according to claim 1, wherein said outer and inner pins project upwardly at equal height from said lower die member.
- 5. The improved blank stop system according to claim 1, wherein said pins are substantially cylindrical are provided with an axial bore configured to receive a retaining bolt.
- 6. The improved blank stop system according to claim 5, wherein each of said pins is provided with a counterbore cavity for receiving a bolt head.
- 7. The improved blank stop system according to claim 5, wherein each of said pins has a diameter of from about {fraction (1/4)} to about 1 inch.
- 8. The improved blank stop system according to claim 7, wherein each of said pins has a diameter of from about {fraction (3/8)} to about {fraction (3/4)} inches.
- 9. The improved blank stop system according to claim 1, wherein each of said pins is freely rotatable about a retaining member.
- 10. A method of making a container from a container blank comprising positioning said blank on a lower die member configured to receive said blank said lower die member utilizing positioning means including an improved blank stop system comprising at least four rotatably mounted inertial blank stop pins disposed on the forward portion of the lower die member and projecting upwardly therefrom;
at least two of said rotatably mounted inertial blank stop pins being outer pins located on said forward portion of said lower die member in opposing relationship to each other at a distance from each other which is less than the maximum transverse dimension of said container blank and which is greater than or equal to the maximum transverse dimension of the formed container, at least two of said rotatably mounted inertial blank stop pins being inner pins located on said forward portion of said lower die member, forwardly and inwardly located with respect to said outer pins, said inner pins being disposed in opposing relationship at a distance which is less than the maximum transverse direction of the container formed from said container blank.
- 11. The method according to claim 10, wherein said container blank has a caliper of from about 0.008 to about 0.050 inches.
- 12. The method according to claim 11, wherein said container blank has a caliper of from about 0.012 inches to about 0.025 inches.
- 13. The process according to claim 11, wherein said container blank has a moisture content of from about 8 to about 12 weight percent.
- 14. The process according to claim 13, wherein said container blank has a moisture content from about 8.5 to about 10.5 weight percent.
- 15. The process according to claim 10, wherein said outer pins project upwardly a greater distance than said inner pins.
- 16. The process according to claim 10, wherein said outer and inner pins project upwardly at equal height from said lower die member.
- 17. The method according to claim 14, wherein said outer pins project upwardly a distance of from about {fraction (1/2)} to about 1½ of an inch and said inner pins project upwardly a distance from about {fraction (1/8)} to about 1 inch.
- 18. The process according to claim 10, wherein each of said pins is substantially cylindrical and is provided with an axial bore for receiving a retaining bolt.
- 19. The method according to claim 18, wherein each of said pins has a counterbore cavity for receiving a bolt head.
- 20. The process according to claim 18, wherein each of said pins has a diameter of from about {fraction (1/4)} to about 1 inch.
- 21. The process according to claim 19, wherein each of said bolts has a diameter of from about {fraction (3/8)} to about {fraction (3/4)} of an inch.
- 22. The process according to claim 10, wherein each of said blank stop pins is freely rotating about a retaining member.
