Abstract
A method for applying loops formed from a supply length of elongate strip material in spaced relationship along a substrate. Lengths are cut from the supply length, and have their ends supported on peripheral surfaces of two circular disks mounted with their axes oriented to position portions of the peripheral surfaces of the disks on which the lengths are positioned at a wide spacing at a first location and to position portions of the peripheral surfaces of the disks at a close spacing significantly closer than the wide spacing at a second location generally diametrically across the disks from the first location and along a path for the substrate. Spaced portions of the lengths are held along the peripheral surfaces of the disks during rotation of the disks to move the predetermined lengths from the first location to the second location thereby forming the lengths into generally U-shaped loops, and those U-shaped loops are transferred and attached to the substrate at the second location.
