Abstract
Apparatus for slitting large metal sheets of substantial length and width is provided. The apparatus includes a slitting machine of the throatless type guided on a track to provide precise slitting of the sheet. The apparatus includes a long hold-down clamp mounted adjacent the slitter and the track. A supporting table is located on the side of the hold-down clamp opposite the slitter and the track and is provided with measuring heads which enable the sheet which is to be slit to first be cut to a precise, given length. Two measuring heads are provided, one of which causes the sheet to slow down and the second which actuates a shear. A lower supporting table is located on the side of the slitter opposite the clamp and both tables are provided with gauge heads for accurately positioning the sheet prior to being clamped and slit. Preferably, a double slit is made along the desired line to substantially avoid distortion of the metal sheet along the slit.
