Apparatus for removing break-out portions from a sheet of material or the like

Apparatus for removing break-out portions from a sheet of material, which comprises:

• a break-out board having a break-out surface with an aperture therein;
• a sheet of material containing a break-out portion, said sheet resting on the break-out surface so that the break-out portion extends over said aperture;
• a break-out member operative to press downwardly through said aperture and press said break-out portion downwardly through said aperture;
• a support surface associated with said break-out member to support said break-out portion, said support surface being guided in the direction of movement of the break-out member, wherein said support surface is movable within the aperture at least partially into a position at a spacing relative to the break-out surface and which in its rest position is located substantially parallel to and beneath the break-out portion in the sheet of material and which is adapted to be transferred into an inclined position relative to the sheet of material upon movement of the break-out portion by said break-out member upon downward movement of the break-out portion, and wherein said support surface comprises a leaf spring having a free end wherein said spring is fixed at one end thereof to said break-out board, while the free end of the spring is disposed in the aperture, and in said rest position said free end is substantially aligned with the break-out surface.
