    摘要： The present disclosure includes an apparatus for feeding a stack (102) of sheet stock in blocks (104). The apparatus includes a backstop (114), a block pusher plate (116), and at least one sensor for determining a height differential between the stack at generally near a lead edge (112) of the stack and the stack at generally near a trail edge (308) of the stack. The apparatus automatically adjusts for warp in the sheet stock. The present disclosure further includes a method comprising obtaining a first measurement at generally near a lead edge side of the stack, obtaining a second measurement at generally near a trail edge side of the- stack, comparing the first and second measurements, and pushing the portion of sheet stock from the stack with a block pusher plate when the 'second measurement is within a predetermined tolerance of the first measurement.
