Abstract
A method of and apparatus for blanking products from pliable sheet material where the material to be cut is supported on a planar support member within the peripheral shape of the final product and after the blanking process has been completed a product-discharge roller is moved through an aperture in the supporting surface to lift the cut product clear of the cutting edge and discharge the product from the cutting apparatus. Additionally, the cutting edge has a portion which separates the cut product and its peripheral waste from incoming material and the peripheral waste is positively discharged from the apparatus by a conveyor arrangement located externally of the cutting edge which defines the products peripheral shape.
