Abstract
An apparatus for correcting the circumferential length of a metal ring has a drive rollerand a driven rollerpositionable closely to each other for training a metal ring W therearound, and a correcting rollerdisposed between the drive rollerand the driven roller. The apparatus also has a first displacement applying unit for displacing the drive rollerand the driven rolleraway from each other when the metal ring W is trained around the drive roller, the driven roller, and the correcting roller. The apparatus further includes spacersfor spacing the drive rollerand the driven rollera predetermined distance from each other when the drive rollerand the driven rollerare released from being displaced, a second displacement applying unitfor displacing the correcting rollerin a direction perpendicular to the direction in which the drive rollerand the driven rollerare displaced and also to extend the metal ring W, thereby to correct the circumferential length of the metal ring W, and a third displacement applying unitfor displacing the drive rollerand the driven rollertoward each other when the drive roller, the driven roller, and the correcting rollerare released from being displaced by the first and second displacement applying units
