Abstract
Irregular lap formations, such as telescoping, are removed by sandwiching the coil between two horizontally spaced, vertically disposed members each engaging lap edges on respective opposite sides of the coil and then moving at least one of these members toward the other.

A method for straightening irregular lap formations in a coil of metallic strip material wherein, on each side of the coil, the edges of at least some laps extend in an axial direction a distance different than the edges of other laps, there being no axial spaces in said coil, said method comprising the steps of:
- placing said coil between a pair of spaced-apart members each located on a respective opposite side of the coil;
- engaging one of said members with the most outwardly extending lap edge on one side of the coil, around the entire periphery of the lap, and engaging the other of said members with the most outwardly extending lap edge on the other side of the coil;
- moving one of said members toward the other member to decrease the distance therebetween and to eliminate the differences in the distances to which said lap edges extend on each side of the coil in response to said movement of said member;
- supporting said coil along its axis in a manner which permits movement of said laps in an axial direction during movement of said member;
- and vertically withdrawing said supported coil, at the conclusion of said straightening operation, without initially employing a substantial relative displacement in an axial direction between said supported coil and said other member.
An apparatus for straightening irregular lap formations in a coil of metallic strip material wherein, on each side of the coil, the edges of at least some laps extend outwardly in an axial direction a distance different than the edges of other laps, there being no axial spacing in said coil, said apparatus comprising:
- a pair of horizontally spaced, vertically disposed members for receiving said coil therebetween;
- means on one of said members for engaging the most outwardly extending lap edge on one side of the coil, around the entire periphery of the lap;
- means on the other of said members for engaging the most outwardly extending lap edge on the other side of the coil;
- means for moving one of said members toward the other member to decrease the distance therebetween;
- said engaging means on said members comprising means for eliminating the differences in the distances to which said lap edges extend on each side of the coil in response to the movement of said one member;
- means for supporting said coil along its axis in a manner which permits movement of said laps in an axial direction during movement of said members;
- said supporting means and said other member comprising means cooperating to permit the vertical withdrawal of said supported coil, at the conclusion of the straightening operation, without initially employing a substantial relative displacement in an axial direction between said supported coil and said other member.
