Abstract
A stripper for stripping coating off of coated sucker rod is provided. The stripper can have a frame having spaced-apart and opposing end plates with a passageway for receiving the coated rod. Rollers located in the frame guide the coated rod as it passes through the passageway. A cutting bar contacts the coated rod to cut a strip off of the coated rod, leaving a remainder of coating that can be deflected off of the coated rod by a deflector as the coated rod passes through the stripper.

A method for stripping coating off of a coated rod, the method comprising the steps of:
- a) providing an apparatus for stripping coating off of a coated rod, the apparatus comprising:
- i) a frame configured for attachment to a rod transfer unit, the frame further comprising a passageway extending therethrough for receiving the coated rod, the passageway defining a longitudinal axis through the frame,
- ii) at least one first roller disposed in the frame configured for contacting and guiding the coated rod in the apparatus when the coated rod passes through the passageway, the at least one first roller configured to rotate about a first axis that is substantially orthogonal to the longitudinal axis,
- iii) a cutter configured for cutting a strip of coating off of the coated rod when passing through the passageway, and
- iv) at least one second roller disposed in the frame configured for contacting the coated rod when passing through the passageway, the at least one second roller configured to rotate about a second axis that is substantially orthogonal to the longitudinal axis and not parallel to the first axis;
- b) placing the coated rod in the passageway;
- c) placing the cutter in contact with the coated rod wherein the coated rod is in contact with the at least one first roller;
- and
- d) passing the coated rod through the passageway wherein the cutter means cuts a strip of the coating off of the coated rod thereby leaving a remainder of the coating on the coated rod.
