ABSTRACT:
A method of forming a closed loop of a flexible strip, comprising conveying an elongated flexible strip in a predetermined longitudinal direction to a predetermined position on a predetermined conveyance plane, detecting the locations and geometry of end portions of the strip while the strip is being conveyed toward the predetermined position thereof, driving two carrier members to move into positions determined with respect to the end portions of the strip in the predetermined position on the conveyance plane on the basis of the detected locations and geometry of the end portions of the strip, transferring the end portions of the strip to the carrier members, respectively, from the conveyance plane, further driving the carrier members to move along paths determined to cause the strip to be gradually deformed into loop form so that the end portions of the strip have respective edges slightly spaced apart in parallel from each other, correcting the positions of the carrier members with respect to each other while the strip is being deformed into the loop form, and joining the end portions of the strip together along the edges thereof after the strip is deformed into the loop form.
