3. The capping assembly of claim 2 wherein the fingers are configured to deflect outwardly.

4. The capping assembly of claim 3 wherein each finger includes a chamfered end configured so as to deflect the finger outwardly with relative movement of a cap along the finger.

5. The capping assembly of claim 3 wherein each finger includes a concave surface configured to engage a cap.

6. The capping assembly of claim 5 wherein each finger is pivotally mounted to a base and further comprising a spring operably coupled to each of the fingers so as to urge the fingers together.

7. The capping assembly of claim 6 and comprising an element operably coupled to the spring to adjust a spring force used to urge the fingers together.

8. The capping assembly of claim 7 wherein the spring comprises a compression spring operably coupled to an element configured to engage a flange of each finger.

9. The capping assembly of claim 1 wherein the container part conveying assembly comprises a carriage coupled to and linearly displaceable on the head in a vertical direction, and an actuator operably coupled to the head and the carriage to displace the carriage relative to the head, the carriage supporting the cap holder assembly.

10. The capping assembly of claim 9 wherein the actuator is configured to float in the vertical direction.

11. The capping assembly of claim 1 wherein the first direction is oriented orthogonal to the second direction.

12. The capping assembly of claim 1 wherein the first direction is oriented obtuse to the second direction.

13. The capping assembly of claim 1 wherein the container conveying assembly is configured to transport a plurality of tubes each in an upright position.

14. The capping assembly of claim 1 wherein the gripping assembly includes opposed grips configured to grip a container comprising a tube, and a support disposed between the opposed grips configured to engage an upper portion of the tube allowing the tube to rotate.

15. The capping assembly of claim 14 wherein the support is configured to provide a downwardly directed force upon the upper portion of the tube.

16. The capping assembly of claim 15 wherein the support includes a rotatable spindle configured to rotate in the direction of the tube when the tube is rotated.

17. The capping assembly of claim 1 and further comprising a label handling system configured to attach labels to containers.

18. The capping assembly of claim 17 wherein the labeling assembly comprises:

a labeling station having two rollers adapted to rotate the container; and

a label transporting assembly adapted to transport a label, the labeling transporting assembly including a third roller positionable relative to the two rollers so as to hold the container between all of the rollers when the label is attached, the label transporting assembly including a slide assembly having a head movable on a rail, the head comprising a pad with apertures configured for creating a vacuum to hold a label on the pad when a vacuum is drawn.

19. The capping assembly of claim 18 and further comprising a fourth roller mounted to move with the pad and positioned to be proximate an edge of the label when the label is disposed on the pad.

20. The capping assembly of claim 19 wherein the pad is pivotally connected to the head.

21. The capping assembly of claim 20 wherein the head includes a spring operably coupled to the head and the pad to urge the pad away from the head.

22. The capping assembly of claim 19 and further comprising a motor to drive at least one of the rollers to rotate the container.

23. A capping assembly comprising:

a gripping assembly adapted to hold a container;

a cap holder assembly adapted to hold a cap;

a motor connected to the cap holder adapted to rotate the cap holder assembly; and

a labeling assembly comprising:

a labeling station having two rollers adapted to rotate the container; and

a label transporting assembly adapted to transport a label, the labeling transporting assembly including a third roller positionable relative to the two rollers so as to hold the container between all of the rollers when the label is attached, the label transporting assembly including a slide assembly having a head movable on a rail, the head comprising a pad with apertures configured for creating a vacuum to hold a label on the pad when a vacuum is drawn.

24. The capping assembly of claim 23 and further comprising a fourth roller mounted to move with the pad and positioned to be proximate an edge of the label when the label is disposed on the pad.

25. The capping assembly of claim 24 wherein the pad is pivotally connected to the head.

26. The capping assembly of claim 25 wherein the head includes a spring operably coupled to the head and the pad to urge the pad away from the head.

27. The capping assembly of claim 24 and further comprising a motor to drive at least one of the rollers to rotate the container.
