<p>Machine contains (a) a driven conveying machinery with transverse fins, (b) a level counter punch, parallel to the conveying machinery arranged in variable distance and reaching at least over the working length and width of the machinery, and (c) >=2 contr-rotating circular knives in the gap between (a) and (b) in a plane parallel to (b) and almost touching one another in a vertical plane, at circumference. Radius of the knives is greater than the distance between the axes of the knives and the axis of an end roller over which the conveyor passes.</p> |
