Improved apparatus and methods for collecting debris generated during a tire buffing operation on a tire buffing machine, the tire buffing machine having a cutting head cutting surface rotatable about a cutting head axis. The system includes a rotatable shroud being rotatable about a shroud axis, the shroud comprising a side member surrounding a majority of the cutting head cutting surface, a cutting head access window to expose the cutting head for buffing the tire casing, and a vacuum suction port that is adjacent to the cutting head access window. The system may further include a driver to rotate the shroud during buffing, wherein rotating the shroud during buffing aligns the vacuum suction port with the projected path of debris being discharged from the cutting head cutting surface.

1. A debris collection system for collecting debris generated while buffing a tire casing on a tire buffing machine, the tire buffing machine having a cutting head rotatable about a cutting head axis, the system comprising: a rotatable shroud being rotatable about a shroud axis, the shroud comprising a side member surrounding a majority of a cutting head cutting surface, a cutting head access window to expose the cutting head cutting surface for buffing the tire casing, and a vacuum suction port adjacent to the cutting head access window; and,a shroud driver to rotate the shroud during buffing, wherein rotating the shroud during buffing aligns the vacuum suction port with a projected path of debris discharged from the cutting head cutting surface. 2. The debris collection system of claim 1, the shroud further comprising: a guide extending from the shroud and situated to contact the tire during buffing for controlling the rotation of the shroud. 3. The debris collection system of claim 2, wherein the guide is situated to contact the tire between a buffing point and the vacuum suction port. 4. The debris collection system of claim 2, wherein the shroud driver supplies a constant force for rotating the shroud. 5. The debris collection system of claim 1, further comprising: a controller for controlling the position of the shroud rotating about the shroud axis. 6. The debris collection system of claim 1, wherein the cutting head axis is parallel to the shroud axis. 7. The debris collection system of claim 1 further comprising: a first gear operably attached to the driver; anda second gear operably attached to the shroud and in mating contact with the first gear. 8. The debris collection system of claim 7, wherein the second gear has a discontinuity about its circumference, the discontinuity located adjacent the access window when the cutting head is in a tire engagement position. 9. The debris collection system as of claim 1, the shroud being rotatable between a guarded position and a buffing position. 10. The debris collection system of claim 9, further comprising: a safety plate for covering the access window when the shroud is in the guarded position. 11. The debris collection system of claim 1, further comprising: a second vacuum suction port located adjacent to the cutting access window and opposite the other vacuum suction port, wherein the driver operates in a clockwise and a counterclockwise direction. 12. A tire buffing machine, comprising: a cutting head having a cutting surface rotatable about a cutting head access; andthe debris collection system of claim 1. 13. The debris collection system of claim 1, wherein the shroud is rotatable about the cutting head for altering the position of the cutting head access window relative to the cutting head. 14. The debris collection system of claim 1, wherein the shroud is rotatable about a lateral curvature of the tire casing. 15. A method for collecting debris generated while buffing a tire casing on a tire buffing machine, the tire buffing machine having a cutting head rotatable about a cutting head axis, the method comprising the steps of: translating the cutting head across a tire to a subsequent location;rotating a shroud about a shroud axis to obtain an alignment of a vacuum suction port of the shroud with a projected path of debris discharged from a cutting head cutting surface, wherein the shroud comprises a side member surrounding a majority of the cutting head cutting surface, a cutting access window to expose the cutting head cutting surface for buffing the tire casing, a vacuum suction port adjacent to the cutting access window and a shroud driver to rotate the shroud during buffing; and,collecting the debris through the vacuum suction port. 16. The method for collecting debris of claim 15, further comprising: controlling rotation of the shroud to maintain the alignment of the vacuum suction port with the projected path of debris discharged from the cutting head cutting surface. 17. The method for collecting debris of claim 16, wherein the step of controlling rotation of the shroud to maintain the alignment comprises: rotating the shroud about a shoulder of the tire. 18. The method for collecting debris of claim 16, wherein the step of controlling rotation of the shroud to maintain the alignment comprises: causing the rotation of the shroud by a servo, a controller, a guide or combinations thereof, wherein the guide extends from the shroud to contact the tire during buffing. 19. The method for collecting debris of claim 18, further comprising: applying a constant force by the shroud driver for rotating the shroud during buffing. 20. The method for collecting debris of claim 15, further comprising: rotating the shroud between a guarded position and a buffing position, the cutting head access window being covered by a guard plate when in the guarded position. 21. The method for collecting debris of claim 15, wherein the step of rotating the shroud includes rotating the shroud about the cutting head to alter the position of the cutting head access window relative to the cutting head. 22. The method for collecting debris of claim 15, wherein the step of rotating the shroud includes rotating the shroud about a lateral curvature of the tire casing.
