US Patent 7765781 Scrapping plate for a cotton picker

A scrapping plate includes alternating channels or pockets offset in the fore-and-aft direction relative each other to accommodate the different spindle paths associated with spindle bars having spindles which are non-aligned or offset at an angle relative to each other. The offset pockets provide optimal spacing between the different spindle paths and the plate to ensure maximum contact between the spindle picking ends and the cotton bolls to maximize overall picking efficiency. In one embodiment, the pockets are identical but offset in the spindle travel direction from each other and include leading and trailing ends which are angled or curved for conforming closely to the different spindle paths.
