Abstract
Abstract Whole oriented items, such as onions, are sliced in a slicer by holding the items on a horizontal cutter-bearing plate and by rotating the plate to continuously remove slices from the lower ends of the items until they are fully sliced. The holding device include a box-like trap and cylinder-operated hold-down discs. The slicer knives are curved to effect a progressive, bias-type of cutting.
