ABSTRACT:
The invention generally relates to an apparatus and/or a method for moving an round flexible member into and out of a well bore, and particularly, to an injector with two or more gripping members which bind the outer surface of the round flexible member; two or more actuators which cause the gripping members to bind or release the round flexible member; and at least one reciprocator for translating a gripping member to move the round flexible member, or for repositioning the gripping member. A method of translating a round flexible member is also provided which includes the steps of binding the outer surface of a round flexible member with at least one gripping members by engagement with an actuator, and translating a gripping member by reciprocator to move the round flexible member.
