A method and apparatus for handling tubulars is provided. In one aspect, the present invention provides a spinner having a first arm having a first roller and a second arm having a second roller, the first arm and the second arm simultaneously adjustable to retain the tubular. The apparatus also includes a third roller capable of urging the tubular against the first and second rollers, wherein at least one of the first, second, and third rollers is actuatable to rotate the tubular. In one embodiment, the spinner further comprises a fluid operated cylinder for adjusting the first arm and the second arm. The arms are adjusted by actuating the cylinder extend or retract the first arm and the second arm.

We claim: 1. An apparatus for rotating a tubular, comprising: a first arm having a first roller, wherein the first arm is adjustable to retain the tubular; a second arm having a second roller, wherein the second arm is adjustable to retain the tubular; a third roller capable of urging the tubular against the first and second rollers, wherein at least one of the first roller and the second roller is movable independently of the third roller toward and away from the tubular, and wherein at least one of the first, second, and third rollers is actuatable to rotate the tubular; a cylinder for moving the third roller relative to at least one of the first and second rollers; and a cam surface on the first arm and the second arm, wherein the cam surface moves against a movable rod and is adapted to move the first arm and the second arm inwardly as the arms are retracted. 2. The apparatus of claim 1, wherein adjusting the first arm and the second arm comprises extending or retracting at least one of the first arm and the second arm. 3. The apparatus of claim 1, wherein the first arm and the second arm are coupled together. 4. The apparatus of claim 1, wherein adjusting at least one of the first arm and the second arm moves the tubular into contact with the third roller. 5. The apparatus of claim 1, wherein the first arm and the second arm are hingedly connected to a guide key. 6. The apparatus of claim 5, wherein the guide key moves in a guide slot. 7. The apparatus of claim 1, wherein the rollers establish a three point contact with the tubular. 8. The apparatus of claim 1, further comprising a tong assembly having: a first gripping member operatively coupled to a second gripping member to retain the tubular; the first gripping member including a first jaw; and the second gripping member including a second jaw, wherein at least one of the jaws is actuatable to apply a force to the tubular. 9. The apparatus of claim 1, further comprising a guide member coupled to at least one of the first arm and the second arm, wherein adjusting at least one of the first arm and the second arm also adjusts the guide member such that the guide member contacts a second tubular, whereby the guide member guides the first tubular into engagement with the second tubular. 10. The apparatus of claim 9, wherein the guide member comprises a guide bar. 11. The apparatus of claim 9, wherein a contact surface of the guide member is flush with a contact surface of at least one of the first roller and the second roller. 12. The apparatus of claim 9, further comprising a biasing member adapted to reduce a contact force between the guide member and the second tubular. 13. The apparatus of claim 1, wherein at least one of the first roller and second roller has a motor for imparting rotation. 14. The apparatus of claim 1, wherein the third roller is mounted on a third arm. 15. The apparatus of claim 14, wherein the third arm comprises a fluid cylinder. 16. The apparatus of claim 15, wherein the third arm comprises a spring biasing the third roller away from the tubular. 17. The apparatus of claim 1, further comprising a second cylinder for adjusting at least one of the first arm and the second arm. 18. An apparatus for rotating a tubular, comprising: a first arm having a first roller; a second arm having a second roller, at least one of the first arm and the second arm is adjustable to retain the tubular; a third roller capable of urging the tubular against the first and second rollers, wherein at least one of the first, second, and third rollers is actuatable to rotate the tubular; and a cam surface on the first arm and the second arm, wherein the cam surface is adapted to move the first arm and the second arm inwardly as the arms are retracted, and wherein the cam surface moves against a movable rod. 19. An apparatus for rotating a tubular, comprising: a first arm having a first roller; a second arm having a second roller, at least one of the first arm and the second arm is adjustable to retain the tubular; a third roller capable of urging the tubular against the first and second rollers, wherein at least one of the first, second, and third rollers is actuatable to rotate the tubular; a guide member disposed coupled to at least one of the first arm and the second arm, wherein adjusting at least one of the first arm and the second arm also adjusts the guide member such that the guide member contacts a second tubular, whereby the guide member can guide the first tubular into engagement with the second tubular; and a biasing member adapted to reduce a contact force between the guide member and the second tubular. 20. An apparatus for rotating a tubular, comprising: a first arm having a first roller, wherein the first arm is adjustable to retain the tubular; a second arm having a second roller, wherein the second arm is adjustable to retain the tubular; a third roller capable of urging the tubular against the first and second rollers, wherein at least one of the first roller and the second roller is movable independently of the third roller toward and away from the tubular, and wherein at least one of the first, second, and third rollers is actuatable to rotate the tubular; a cylinder for moving the third roller relative to at least one of the first and second rollers; and a guide member coupled to at least one of the first arm and the second arm, wherein adjusting at least one of the first arm and the second arm also adjusts the guide member such that the guide member contacts a second tubular, whereby the guide member guides the first tubular into engagement with the second tubular. 21. The apparatus of claim 20, wherein the guide member comprises a guide bar. 22. The apparatus of claim 20, wherein a contact surface of the guide member is flush with a contact surface of at least one of the first roller and the second roller. 23. The apparatus of claim 20, further comprising a biasing member adapted to reduce a contact force between the guide member and the second tubular.
