Have some fun

Я не понимаю, я думаю, что они являются штамповать!

Совершенно понятно! Летучие подставки - самые лучшие!

I’ve never seen that happen before, going to be a classic letterpress video I think.

Hilarious.
Nick the die next time and you won’t have to play catch.

How is that happening? I’ve never die cut on my windmill.

Normally, when die-cutting, the die is “nicked” in a few chosen places- meaning you take a file or some abrasive instrument and cut a small bit of the die away.
The nicks actually create areas where the die doesn’t cut all the way through the stock- because of this they make little ‘tabs’ that hold the die-cut form in place rather than allow it to pop out all the way before you may wish it to!

If you only nick the die a couple times the form is still easy to separate from the sheet in a process called weeding, after the stacks are die cut.

If you don’t nick the die at all, you end up with what is happening here- the pieces fall out as the press is running (in this case they’re popping out and flying away due to ‘centripetal force’ of the windmill’s gripper bars and their rotation).

Hopefully having it explained doesn’t make it any less funny!

Rather than ‘nick’ the die - and ruin an expensive piece - simply take a centerpunch and ‘nick’ the cutting plate at the required spot. There may well be times when the bridge is better moved to another location on the stock; it’s very difficult to repair a marred die. :o)

Thanks, HavenPress. It’s still hilarious, even though I understand it better now!

Forme- Thanks for the tip, I’m no die-cutting expert :-)

I just hit the die in a couple of spots with my line gauge to nick the die. I never heard of nicking the cutting plate, there always seems to be something new to try, I don’t like to nick the dies so i’m going to try that nicking the cutting plate, great tip.

@forme we try to do everything we can to not cut into our die jacket when running a job. Looking for just a little shine on the die cutting jacket….

Besides that it is a bit of a game of skill, a marked up die jacket makes the next job all the more difficult.

How do you get around the die jacket being marred interfering with future jobs? Maybe we just have a good die vendor, but it seems that re-ruling a die is cheap compared to good die cutting jackets.

Maybe forme is pulling your leg?

Nick the die not the jacket
Slow down the press. Get the rubber away from the rule. Rubber too close to a nick will break the nick too soon. Funny video

As as former die cutter/finisher you never ding the jacket. With a new die you nick the leading edge first, small nicks using a small chisel that way you can deepen the nicks if the piece is still falling apart before getting into the delivery. It is always easier and less expensive to re-knife a die than to keep patching a die jacket - TedvLavin

Different strokes……..:o) The chances of striking the jacket mark during another die job is remote. Even should such occur, filling in a ‘ding’ is far less expensive than is die replacement. Unless things have changed, jackets are far less costly than dies; unless of course you are hung up on only using stainless steel surface Anyway, give it a try.

In forty years this is the first I ever heard of nicking the jacket. I hope all my competitors nick their jackets. As a diemaker I never liked to see a die nicked but knew it was often required. A simple die might cost $60.00 but a good jacket will cost a few hundred and on larger diecutting presses over a thousand.
The ding in a jacket to create a low spot will also create high spots elsewhere and you will end up chasing the makeready when kisscutting or doing fine diecutting.

Well, ding my jacket!!———NOT!!

Again - all the reasons not to do something from all the people never having tried same; little wonder Rupert Murdoch had such easy time. :o)

I have to say I would be very unpopular if i put dings all over the jackets on the presses I run . we leave rules out and trim out of the parent sheet where possible so as to get increased revs , I hate having to put nicks in but needs must if you have twenty odd hours run , I prefer little by little with a quality needle file . I did a makeready for a carton company the other day i had to put Sra2 sheets into the delivery to help the sheets stay together as they rolled round the chain ,it helped with a few strikes here and there with a file . It is not good to have your work mashed into the bed gears on a press ,that costs more than any die if a rack breaks .
platens its not so bad you just have to pick them up when you cant stand looking at the job behind your delivery !

Did anyone notice the magical lockup no funiture, no quoins,?

Continuing to flog that horse……. Nowhere in the original suggestion was it implied that all die-cutting be henceforth mandated to mark the die-jacket rather than the die proper. However, such is the hyperbole (“…in all my forty years….! snort, snort, puff, puff)”) of those unaccepting of change that any procedure outside (their) experience is considered simple heresy of orthodoxy and must be dismissed. Just try the procedure; it’s not for every job of course, but it is another way to perform a task.
“Our wretched species is so made that those who walk on the well-trodden path always throw stones at those who are showing new road.” - Voltaire

forme
Nowhere did I state (“…in all my forty years….! snort, snort, puff, puff)”)
I have never dinged a jacket on purpose but have seen the inconvenience caused by same. So not outside my experience.
Keep the forward thinking ideas coming.
