Looking for an equipment maker

[swertel]

Part 1
We have a old (circa 1960's) rubber press that is now in need of some safety enhancements. Before we begin tearing the machine apart, I was hoping to get some information about it from the manufacturer. I looked through the Thomas Register as well as a general internet search, but could not find a company with this name (as expected).

So, all of you senior engineers out there, have you ever heard of this company and what may have happened to them: closed their doors, changed their name, whatever?

Rubber Equipment, Inc.
9827 Remer St.
El Monte, CA

I'm looking for information on their machine with serial number: URM-16-16-36-145.


Part 2
This rubber press has two giant, internally water-cooled rollers. We take the bulk material and toss it, literally, between the two rollers. It always sticks to one roller and not the other. With the equipment that we are able to take to the location of this machine, we can't determine any noticeble difference in the two rollers. Does anyone know how this works?

TIA,
--Scott

ONE SOURCE FOR YOUR INQUIRE COLUD BE SOME INSTITUTIONAL ASOCIATION LIKE CHAMBER OF COMMERCE AT EL MONTE CALIFORNIA.
I got this kind of info for others firms. Ask them about it
Tell them what is your interest.


Part 2
see for differents temperature at the rollers surface, and the quality of such surfaces.

Where is the machine located? You can reach me at k281969@hotmail.com

Part 2
A temperature difference was my first guess also, but the cooling water has the same supply for both rollers. So, everything else being equal, (i.e. no major heat dissapation or flow devices inside the rollers that are not visible) the temperature of the two rollers must be equal.

I also assumed the surface texture to be different, but we can't get inspection equipment in that area to check it, and there is no difference by feel.

My other guesses are that one roller is slightly larger than the other. I haven't brought a string down to the machine in order to measure the circumference, yet. The final guess is that one roller is slightly above or below the other, but I can't determine the dynamics of that.

You must check the outgoing temp from each drum.

How would you check the temperature of each drum?

We can't use a laser thermometer in the area. The temperature should be read while the machine is in operation, so taking a physical reading off a rotating drum would prove to be difficult at best.

Is there another piece of technology I'm missing?

Why you can not use a laser thermometer?
Laser is the pointer, thermometers are infrared.
There are infrared thermoter with out laser pointer.
If not , you can look for sticker or label temperature sensor.
Other way is to put a temperature bulb at the water outcoming from the drum, they must be equals, use the same thermoter changing from one location to the other.
By this way you get the same meassure and can compare the values.


Please clear about:
Incoming water temp:
Out coming from each roller:
Temperature to be mantained:
Does the ruber stick allways at the same drum.
Maybe one of them is under differents conditions.
Check for air currents, heat goin from the down drum to the
topdrum.
Try closing the water inflow at one of them and see if condition changes.
I insist please contact me at my e-mail, but if for any reason do you prefer to be in contactc by this way, I will
help any way.

Having designed a few presses in my time it seems to me you are laminating something. Different diameters with the same gearing/belting would mean a sliding nature/dont hit same place thing. These sound like cooling drums and may or maynot have in-line temp's. Hows you bathrooms? any deposites? Some week-end, check the volume of each drum. Sounds like the inners are caked. Flush or run strippers. Changed your material lately? Maybe a od drum cleaner is needed.

Pardal,

Did you have a chance to look over the pictures?

"We can't use a laser thermometer in the area."

If you mean infrared, I am curious about why you can't use IR. (Full disclosure: I'm a design engineer at an IR thermometer company.) Unless there is absolutely no room for a small cylindrical IR sensor, the moving roller situation is one of the classic applications that IR is perfectly suited for.

Call me at 831-458-1175 Ext. 397 if you are interested.

I was under the impression that the thermometer was laser, not IR. IR may be useful in the area. The radiation from the laser may set off the explosives. I don't want to be the guy to test it.

As was mentioned by "pardal", the laser is just an aiming aid, and its use is optional (operator energized or ignored). Most IR thermometers don't have them anyway.

If your rollers are large, you don't need a the functionality laser pointer.

Ircon, Williamson, Land are others. (Raytek's are the best, of course. ;-))

Wow,

Building solids are we? Try running a caul (cookie) sheet through with the rubber if you're trying to make a flat sheet. If you're trying to make it mix, how about a scraper - look at "steam rollers" used to make road surfaces flat. Watch out for static if you use a non conductive cookie sheet.
