<p>A guillotine machine for shearing metal, power driven or hand operated, including a yieldable supporting element located in a resting position adjacent the loading edge of the first blade in the path of the second blade and a biasing mechanism acting to resist displacement of the support from its resting position as the second blade is advanced over the first blade so that the material cut by the machine is maintained in a flat and untwisted condition requiring no straightening operation.</p> |
