If you call it a leaf,

General idea:

The width of the metal sheet (the "blade" you mentioned) can be cut to about15.8-16.1mm. The thickness is about 0.15mm ~ 0.19mm and the length is about 200mm ~ 1500mm. The length of the top hole (hole) is about 62 mm ~ 300 mm

That is, the cutting length of this machine is 200- 1500mm, the width15.8-16.1mm, the height (thickness) is 0. 15-0. 19mm, and the length is 62.

Cutting may mean that it can be cut into ... (range).

Under the conveying cylinder (without collar). As you can see, there is nothing in it ~ it's just hollow ~

three

Correct.

The high-low speed changeover switch can adjust any gear from high speed to low speed.

I don't know what the landlord's machine is, but it's probably about cutting.

If you don't understand, you'd better consult your colleagues in Japan.
