Abstract
Sheet metal plates are automatically fed for processing to a computerized numerically controlled sheet shear arrangement by means of the feeding apparatus. This feeding apparatus comprises a feeding bar arranged parallel to the cutting blades of the sheet shear arrangement and movable perpendicular thereto. Elevationally displaceable or movable holding elements are arranged on opposite sides of the feeding bar. On the side of the cutting blades the holding elements retain a first sheet metal plate intended to be cut and on the opposite side grip a second sheet metal plate which has been elevated by suction elements. During the cutting operation performed upon the first sheet metal plate the second sheet metal plate is drawn to a working table within an overlapping time interval and placed upon the working table. After sectioning the first sheet metal plate the second sheet metal plate bearing upon the working table is pressed against stops located on the rear side of the working table conjointly with the rearward movement of the empty feeding bar. Subsequently the second sheet metal plate is gripped by the holding elements on the cutting blade side of the feeding bar and the same o…
