The finished drawing goes into production.
One of the most difficult technological operations is to make the parts cut and folded. That is why you do not need scissors. Freely separating parts from the general sheet, you can quickly and neatly glue the polyhedron.
And this is how this machine works:
The printed sheet goes on top, then a special stamp makes cuts out and presses down fold lines. In addition, the speed at which the machine operates is equal to one sheet per second. Just imagine how much time you need to cut all the parts with scissors. Or 1 second.
After completion of the operation, the finished sheet neatly folds on the pallet.
Machine production of the German concern Heidelberg (Heidelberg).
The company has a history of manufacturing machine tools for the printing industry since 1850 and is a world leader.
Vladislav is the "сhief master" of this wonderful car.
Only due to its fine tuning many hours of time it is possible to obtain a product of the highest quality.
The final stage of processing parts is cutting sheets to the usual A4 format.
A huge knife works simultaneously in two planes - vertically down and horizontally along the length of the knife. The blade of the knife makes a shift to the side when lowering. This method of cutting allows you to simultaneously cut a large number of sheets without damage, skew and achieve high accuracy of the cutting line.
Five hundred sheets are cut in one motion, as if it were a piece of butter.
After that, the finished sheets are folded and packaged.
There are five regular polyhedra: a tetrahedron, an octahedron, a cube (also known as a...
