Heidelberg Windmill Hot Foil Unit Questions

Hi there,

I have a Heidelberg Windmill Redball that came with foil stamping capabilities. I am attaching a variety of photos because I’m out of my depth with this thing. I’ve foil stamped before, so I know the general principals and setup.

Questions:
1) How do I feed foil through this? I might have some kind of bar that could, perhaps, mount underneath the chase area for foil wrap up? Otherwise there is that mystery bar behind the press??

2) How would I lockup this foil base? It has so many cords coming out of it.. (Yes, I realize some of those cords have seen better days, so they might be a safety hazard, haha.)

3) Just any general advice about this foil setup and it’s function would be great. I am uncertain how to search for it to find anything like a manual or anything..

Bonus question: Can I use my fountain with this setup? I cannot figure out how to drop down the fountain tray..was going to clean it/dust it when I first got the press but was unable to. Also there is no numbered gauge for setting the fountain.

Help!! :) Thank you!

EDIT: Of course image uploading isn’t working, hold on…

Hopefully this link will lead you to an album of photos! :)

hey there.
PURPLE: is a foil guide rod
BL/YELLOW: is the area to lock plate into the chase. I would find and use a few layers of MICA to insulate the plate from furniture.
YELLOW: looks like the clamp to put cables in. this should keep them from getting mashed.
LT BLUE: is a bunter post for attaching the die. you need a minimum of 2.
ORANGE: is one of the power plugs.
the shielded thermocouple prob screws into the bottom or top.
There is a rod with brackets that mounts down below the chase area. that is where foil goes. The problem with this set up is, there is only so much room in there when it closes. It then forces you into small rolls; A) 400ft? or less; and ordering foil on 1/2 inch cores.
It looks to be fairly complete except for the lower foil rod. I am wondering if they didnt try running foil through the frame . That might explain the extra rod and pillow block bearings on the back. if so, that would Really cut into options as far as working area.
Good luck

Thanks, Ericm!

I should have that rod, I’ll poke through my box of supplies. And a bunch of random foil came with the press, so hopefully it is mostly stuff that will work with this setup!

So do I only need to lock the base up in the one direction, then? As opposed to one vertical quoin and one horizontal?

if you have some short furniture and can work around the wires, then do it both ways. Your set up may change to meet requirements of specific jobs. But, a heat plate like this cannot be locked up “Too good”.

Ok, that makes sense.

I found the foil rod! Now..how to attach it?

The way that seems obvious (unscrew bottom bolts until I can slide notches of the foil attachment on, tighten bolts again) …cannot be done with the chase in there.

My next move would be to attach to the front of those bottom “base” pieces (the first photo)..but there isn’t any spot to screw into? Or maybe I’m not seeing something.

Photos attached, hopefully my explanation makes sense. :)

Or, it is possible that, that specific foil bracket was never in that specific press. Many times, things get “thrown together” and not really looked into. Your best bet may be to find someone who knows a bit of drilling and tapping and have some mount holes/bolts/brackets put in there for you. Look for unused holes down the sides right there. there maybe some “L” brackets used to bring the vertical side surface to horizontal.

Thanks for the input, Eric! I’m not sure, I’ll have to keep investigating.. the notches on this foil bar fit the screws under the platen there (the first picture) exactly so it seems like it was made for this press. But it’s hard to get it screwed on…hmmm… :)

Annie- That’s the correct foil bar for the press.

The two metal blocks hang down and the two slots slide onto the bolts. Basically, turn the bracket 180 degrees from it’s position in the second to last photo.

John, The rail hangs, what looks to be upside down? with the foil roll clamps/guides hanging down then? I dont know. i dont have a foil unit for my mill.

If you desire not to do foil stamping I would be interested in buying the heat plate.
Thanks

Hi there,

Jumping back in here…

I had mostly figured out how to attach my foil roll and feed it. I was having some issues with even heating though — the wiring that came with the heating rods is pretty beat up.

Does anyone have any ideas about where to get new rods?

Things get hot..so all the connections from the main switch through the press are working..just the wires to the rods themselves are a little fussy.

I could also use another..thing..for holding my foil dies in place. I’m not sure what to call it..the little screw post item. :)

Thank you all for your help as always!!

you can find “bunter posts” at “sterling toggle”. you may need to have an account. if so, reach me. i will get them and have them drop shipped to you.

The heating equipment on the foiling unit can be replaced and upgraded with standard industrial and scientific components like those available from Watlow or, at the low end, Auber Instruments. West Coast Plastics is a distributor for Watlow heat controllers, relays, thermocouples, and cartridges in the US.

You should be able to pull the specs from the casing on the cartridge heaters and find a suitable replacement from Watlow.

As EricM said you’re looking for Bunter posts to attach your dies. One additional note is that you need the low height metric posts to thread into your baseplate. American Printing Supply stocks them in the US and marks them for Heidelberg.

I have a windmill with the foil puller like yours. I had never tried foil before but figured I would teach myself what to do. When I tried the used hot plate I had gotten it was a wiring mess. I did what I could to clean up the wiring slices and mess. The first time I turned it on it shorted out and blew the rods and and controller. I also had an old Boss controller and when I pealed off the nameplate found it was made by Watlow back in day for Boss I guess( long before the internet). I bought new Watlow rods and a new thermocouple. I figured Watlow rods - Watlow contoller should work well. I made sure I got the insulated braided protected wires so the rods could not ground out like they did before. I had to create a work around for the thermocouple to get it seated in my plate. I hooked it all it and it worked fine. I have the undermount foil setup like yours. I buy my foil from Infinity and had them reroll it. By rerolling the foil I had a easier time controlling the tension as it came out up off the spool. It no longer would rub the bracket plus it stays away form the die and stopped the preheating of the foil. If up put a roll in backwards you will see it spools from the front of the roll not the back under the bracket which was why we reroll.

I have recently obtained a 10x15 H platen with foil capabilities like the one Anne has posted photos of - i also have a std red ball platen and grew up running letter press just before offset came in - this foil machine looks like it has not run foil for a long time and is missing quite a few parts to run foil - i did not get a heat plate with it and it looks like i would need a special chase to accommodate the wires etc. as well as a tension roller to for foil draw and the carriage for the foil that sits under the chase - it has an older looking heat controller
does anyone know where i might be able to obtain a heat plate and the connecting wire and a chase etc. also the top roller for the pick up on the used foil? - thanks roger

Roger, we ground out a small portion of a chase to accommodate the wiring (at the top). We attached a small plate over it to keep the wires from flopping around.
best,
Bruce

I stumbled upon this thread about foiling on the 10 x 15 windmill. I recently acquired a similar press and am needing some assistance. The press I have has what looks like an original heat controller. I purchased a chase set up with a small heat plate. The plate had the two square 4-pin plugs attached to the heat rods and what appears to be a thermocouple with a round 3-pin plug. On my windmill there are only the two square plugs - no place to plug in the thermocouple plug. When I plug the square plugs in and turn the unit on the red light comes on but nothing heats. What should I do to troubleshoot this and get it going? I’m attaching several photos of my setup.

Some basic electrical trouble shooting is needed using a multimeter. Don’t know where you are, but here in the USA, a cheap meter, which is all you really need for this, is 5-10 bucks.
If you not familiar with electricity, and trouble shooting, best to get someone in there who is.
The red light is for either “power” or “heating”. Green light is prob for “At selected heat value”, or “At selected temp”.
A) check for value of supply voltage. The red light comes on, so there is something there, find out what it is.
B) Is this voltage showing up at the plugs from control unit.
C) what is resistance of the heaters. are they the same value., or “shorted out”, with either 0 ohms, which would blow a fuse, or “infinity”, which then just wouldn’t heat.
D) the round connector, is for the thermocouple, or temp sensor. It may be a 3 pin, but only use 2 of them. Look for an open hole in the edge of the hotplate. check with something, stiff wire is fine, just unplug the power, to see how deep it is. If it is in the center, and about half the depth of the hotplate, this is prob where the the heat sensor probe goes. Otherwise, if there is a “kind of oddball threaded hole someplace, this could be where a “screw on”, or, “eyelet” type sensor would screw on to the face of the plate.
I am in Milwaukee, Wis. and would be happy to look the system over for you, recommend parts needed, and repair.

Thank you for your response! It is very helpful to get ideas from someone who is more familiar with this. I did a little more investigating and I’ll bring a meter in next week to do some more diagnostics.

I opened the controller and translated (German to English) the legend on the connections and it appears the power to the heat rod is supplied by two wires which run in a sheath and three wires which feed in a separate sheath to the other 4-prong plug to connect to the thermo sensor. This would lead me to believe you could only power a single heat rod at a time unless the socket pins are connected together in which case you could power two.

The foiling chase I bought didn’t come with this press. It has the two 4-prong plugs. Each one has two sets of 2 wires - so each plug powers 2 heat rods for a total of 4 rods. There is a thermo sensor with a spiral metal sheath shielding the wires and a round three prong plug. My press has no place to plug this in. The way the press appears to be wired, it would plug into one of the 4 prong plugs.

It is becoming more apparent that I’m going to have to rewire either the sockets on the press or the hot plate so the two units will work together. Or add a socket to accept the three prong thermo sensor plug.

Wire block:

Pins:

1,2 input voltage

3,4 880watt heater

5,6,7 thermo sensor

8 ground

Well, do your testing first, then maybe disassemble the connector for the sensor and see if it is really using three wires or 2. A typical “J” type thermocouple has (+, white)and (-, red) leads. they are polarity sensitive.

The man who I obtained the windmill from told me the cover on the other side of the chase latch came off and underneath the cover was the plug for the thermo sensor.

So I plugged everything back in and the controller seems to work. It seemed like only 1 or 2 of the heat roads which were wired to the plug on the left were heating. So I may have some bad heat rods. I could only heat the plate to 200 degrees.

So not such bad news. I’ll check the resistance of the heat rods in question and go from there.

I like it when I learn something :)

In my case after trying to electrocute myself by fixing the existing wire and such I replaced my my rods and thermocouple. I used only the connectors but changed every thing else. I have a post earlier in this thread of where I got the rods and such. If you cant get the thermocouple out you may be able to use one of the existing rod hole instead. After making my plate safe and sane I still had issue’s or thought I had issue’s with heat. It turns out the laser temp reader I was using was not able to read correctly off of aluminum. For a number of months I had been way to hot so it did not work. I had a Boss foil controller which when I peeled of the nameplate says Watlow underneath. Watlow had made the controller for Boss back in the day. I used that info to find old schematics. I then used Watlow rods since Watlow is still around. You said got the temp up to 200 and the controller says a high end of 200C which 392 F which is to hot for foil.

To make a long answer short I backed off my heat and tried a few sheets. Little by little I increased the heat and tried again. I found that what I thought was not enough heat was way to much and had caused the foil did not stick. When it did not stick I went higher and made it worse all because I thought my laser reader was correct I now foil all the time.

This is only getting up to 200 F or about 110 C, so not warm enough. I wonder if the other two rods were heating if it would get warmer. I can only get two rods to heat as the other socket on the press seems to be dead. I guess I’ll need a meter and do some checking for voltage in the socket. I’m thinking I need 300 F degrees to work properly.

Control Panel: There is a fuse under the Black screw in Knob, start there,

The Label indicates 220 V input, what do you have on it?

Something to try. When I first stated with my plate it had a lot of poor wiring. Another mistake I made was I went to Granger and explained what I was doing and bought wire to rewire all the connectors. Turns out is was the wrong kind and type of wire and I think it effected the thermocouple responce. I ended up replacing the thermocouple and rods with proper braided wires and all is good. In theroy if the control box is working when you turn it on from a cold start a light should go on. After it heats to a a point the therocouple should turn it off and light should change or go off as the system controls the heat. If you start at a very low setting see if the unit heats then turns off as it should. You could have a bad thermocouple or bad incorrect rods or both.

different metal surfaces, textures, and colors will reflect back differently to those laser temp sensors. best to get a contact type if there is a question. you don’t even want, to get into IR camera’s pricing. I you can borrow a contact style from someone for a day, you could, set a bunch of diff temps, read them with the laser, then verify actual with the contact temp. record your results and then the laser is prob usable. you don’t need to be accurate to the exact, “oneth degree”, for the foil to work.

Hi Ericm - In my case I was basing my feedback on the laser reader. I flet going higher tech was a good thing and I was wrong. Because the temp reading was wrong, I was trying to foil at around 400 F or higher which did not work. At the time I gave up thinking I needed a new plate and controller which I could not afford and put foil on the back burner. I discover by chance the laser reader was wrong and could not read from the plate material like I thought. I retried foil starting at temp way to low and stepping it up in controlled amounts till it did work. In fact, Ericm I think you even help is back at that time so thanks again. I used my laser reader to take my temp the other day and see if I had a fever during these strange times. I discovered what I thought, I am not a hoteee after all.
