<p>A sensing mechanism for use with a paper cutting machine having a table (17) for supporting a pile of sheets to be cut. There is provided a knife (18) for cutting the pile (14), a clamp (15) for the pile (14), means for operating the knife and means for moving the clamp (15) up and down, a back gauge for movement along the table against the pile (14) to position it for cutting, and means (13) for moving the back gauge forward and backward. An optical sensing means is provided for positioning over the table (17) to observe a target area of the surface of the top sheet on the pile (14), containing marking indicating a desired cutting line. A visual display means (C) is located remote from the sensing means and operatively connected thereto to display a visual image of the target area. The display is provided with reference marking for registry with said cutting marking on the top sheet when the pile (14) is in a position a known distance from the cutting position.</p> |
