<p>The tool comprises a plate (9), on which a self-centering cutting knife (10) is suspended. A pair of co-acting pulling off rollers (18a, 18b) are provided adjacent the cutting knife (10), said pulling off rollers pulling off the moulding excess, such as fin material, cut off from each blank. The resulting removal of the moulding excess from the plastic blank is more accurate than hitherto known also from blanks with concave surfaces with the result that the surface of the finished blank is provided with a smooth appearance. <IMAGE></p> |
