A configuration for the transport and simultaneous alignment of sheets has a straightedge, at least one conveyor belt disposed slightly at an angle to the straightedge in the direction of movement of the sheets, and an air suction device. A moving portion supports the object. The planar surface defines a plane and the centerline extends in a direction between the proximal end and the distal end. A force applied to the slide stop, either manually or via a cam on the slide when the slide is pulled back and released, will move the finger out of its supporting position and allow the slide to move to battery. A device comprising a gauge containing a piston enables to pre-calibrate and store the desired drilling depth.
