摘要 |
A tool for scoring a metal container component has a scoring blade having two faces which define the shape of the score and which as viewed in section converge substantially to a point. The angle between the two faces is of the order of 75 DEG to 120 DEG and is preferably at least 90 DEG , the optimum angle being 90 DEG . The specification also described a method of scoring the component in which the scoring blade is engaged with a portion of the component which is radiused upwards towards the blade. |
