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.

A looper for thick metal strip, the looper comprising:
- a large-diameter outer basket centered on an upright axis;
- a small-diameter inner basket axially above the outer basket and centered on an upright axis;
- input means for feeding metal strip on edge and generally tangentially into the outer basket to form therein a large,;
- diameter spiral having an inner end;
- output means for feeding the strip upward from the spiral inner end around the inner basket and tangentially from the inner basket;
- and
- means for straightening the strip generally as it leaves the inner basket.
A method of looping metal strip, the method comprising the steps of:
- feeding the strip horizontally on edge into a large-diameter outer basket centered on an upright axis and forming in the basket a large-diameter multiturn spiral having an inner end;
- guiding the strip from the inner end upward in a helicoid of less than 360° around a small-diameter inner basket axially above the outer basket and centered on an upright axis;
- and
- a pulling the strip horizontally and tangentially from the inner basket above the spiral in the outer basket.
