Abstract
A looper for thick metal strip has a large-diameter outer basket centered on an upright axis and a small-diameter inner basket axially above the outer basket and centered on an upright axis. The strip is fed on edge and generally tangentially into the outer basket to form therein a large-diameter spiral having an inner end. Then the strip is fed upward from the spiral inner end around the inner basket and is finally pulled tangentially from the inner basket. The strip is straightened generally as it leaves the inner basket.
