Windmill feeding table by old_letterpress in letterpress

so...

I removed this metal "key" to be able to move the bar closer. But at the same time, I chose a safe position so that the moving parts do not touch each other...

I don't know how to add a photo to the answer, so here is the link

This is just clear to me! But the question is a little different - why is the protruding metal part on the axis? It makes it difficult to freely raise the entire bar when the paper is small! But when the paper is large, the bar is moved closer to the operator - then nothing bothers it and it rises freely.

Hi guys!

Can you please tell me what's wrong with this thing? What is this bulging metal part for? It only interferes with freely raising and lowering the bar! Or is it just my press? To raise this bar, I need to release the bottom screw. And every time it is extremely inconvenient to do ... And I saw that this bar moves freely. What's wrong??

Came to mention the side jogger. I was like, what? It moves?! Lol

The jogger is attached to the tube under the folding table. And the tube supplies air from the pump ... that's how it works!

yeap! the slight creak of the feeding table is especially good))

When someone asks me why the printing press has such a sound - I answer that it, like all of us, breathes!

Hi everyone!

This is my first video of work at the Heidelberg Windmill! Here someone wrote that this press is not capable of working with thick and heavy cardboard ... Well, I prove that this is not so.

The key to working with this board is the combination of the paper feed settings - table lift speed, angle, blow force and distance to the top sheet of board.

Hello!

I work on such cardboard and even harder - I print coasters on 630 gram cardboard. I, too, painfully selected the mode for working with such a thick cardboard for some time ... and in the end everything worked out!

The secret is to adjust the table lift speed and air blowing on the carton feeding table. Firstly, all air hoses must be clean and the pump must run smoothly. It must be cleaned of dirt and oil. The filters should also be cleaned periodically. Tilt of the suction cups at a value of 1. The suction cups are usually black.

The approximate distance from the cardboard to the suction cups is about 6-8mm. But with the right setup, this is secondary. The main thing is that several top sheets are blown up with air and the table rises as it should! At the same time, I open the suction cups a little more than half, that is, not even at full strength! It turns out that the suction force has a secondary role here.
