ABSTRACT:
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 bending 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 straightener roll area. An end bender roll and two of the straightener rolls are mounted on a pivotal frame connected to a piston cylinder assembly which causes the frame to be rotated through an arc in a direction to either bring the end bender roll into an operative position while the two straightener 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.
