Patent ID: 7895928

Claim:
A shear device, comprising: a material guiding mechanism; a shear head including a shear blade disposed proximate the material guiding mechanism; means for translating a first movement of one of the shear head, and the material guiding mechanism into a second movement of the other of the shear head, and the material guiding mechanism, wherein the material guiding mechanism includes a material delivering portion, and a material removing portion, wherein each of the material delivering portion and the material removing portion includes a first conveyor track, and a second conveyor track, wherein the means for translating includes a first link member that connects the first conveyor track of the material delivering portion to the shear head; a second link member that connects the second conveyor track of the material delivering portion to the shear head; a third link member that connects the first conveyor track of the material removing portion to the shear head; and a fourth link member that connects the second conveyor track of the material removing portion to the shear head, wherein the first movement is a rotational movement of the shear head, and wherein the second movement includes lateral displacement of the first conveyor tracks in a first direction and lateral displacement of the second conveyor tracks in a second direction opposite the first direction wherein the first and second conveyor tracks of each of the material delivering portion and the material removing portion are parallel to one another, wherein the shear device includes means for adjusting a parallel spacing of the first and second conveyor tracks of each of the material delivering portion and the material removing portion.
