ABSTRACT OF THE DISCLOSURE A method and apparatus for uncoiling material such as wire, from a coil supported about a horizontal axis by a drum, including separating a loop from the coil, and bend- ing the leading end of the material upon its exit from a pinch roll unit so that it takes a path generally parallel to that of a predetermined passline, and straightening the material once the leading end passes through the straighten- er roll area. An end bender roll and two of the straighten- er rolls are mounted on a pivotal frame connected to a pis- ton cylinder assembly which causes the frame to be rotated through an arc in a direction to either bring the end bend- er roll into an operative position while the two straighten- er rolls are in an inoperative position, or to bring the end bender roll into an inoperative position while the two straightener rolls assume a nested relationship with a fourth roll in an operative position.
