Abstract
Abstract Apparatus for subdividing sheets of material, such as thin sheets of titanium, into small coupons or pellets. Feed rollers are provided for selectively advancing the sheet material over the surface of an anvil having a front edge that extends in notched outline defining spaced-apart teeth. A unique arrangement of flying tools are radially mounted on discs stacked upon a rotatable arbor in front of the anvil, with the tools being adapted to intermesh with the anvil teeth and cut coupons from the sheet. The top of the anvil is located above the axis of rotation of the arbor so that the coupons are removed from the sheet by shearing action.

Claim 1
Independent Claim
160 words
Sheet reducing apparatus comprising a framework, anvil means associated with said framework having a surface for supporting material to be reduced into coupons, a rotatable arbor associated with said anvil including a first plurality of discs mounted thereon and a second plurality of discs mounted thereon interspersed with the discs of said first plurality, tool portions mounted on said first and said second plurality of discs that extend radially outwardly from the arbor and the discs mounting the tool portions, the tool portions mounted on the discs of said first pluraLity extending radially further than the tool portions mounted on the discs of said second plurality, the tool portions mounted on the discs of said first plurality having outer extremities that are wider than the discs of said first plurality and said other extremities on rotation of the arbor moving in paths that project into the cutting paths defined by the tool portions on the discs of said second plurality.
