I seen
@T Monahan post in the classified section in regards to asking what's the durometer reading on the rubber rollers...
For us less fortunate who are stuck on a rock in the middle of the Pacific Ocean, What are the pros/cons of a flat bed wringer?
I can only assume some rugs can't pass through them? Do the wringers need to be adjusted yearly for maintenance or is it automatically adjusted? Is it a one set pressure for all types of rugs?
I've been told flat bed wringers are more for production cleaning as a centrifuge wringer is more for people who don't clean xxxx amount of rug... Yes I understand that a spinner can get more water out of a rug but you can't put bleeders through it...

1. Durometer reading on a newly produced
MOR Wringer Roller will be +/- 65. As the rubber ages, it gets harder and the reading goes up. Many rollers that I have seen 12 to 15 years old, have a reading of 90-ish. This is too hard. When it is hard that hard, the lack of flexible rubber during the compression, to squeeze the rug, looses its intended effectiveness. You need the lower durometer reading to have an optimum wringing process.
2. Wringers need their bearings and chains lubricated. Appropriate chain tensioning is important maintenance inspection. The compression wringers on some
MOR Machines were done with hydraulic cylinders, other more recent versions are with air cylinders. In each model they are set or a certain pound per square inch to insure optimum wringing. (equivalent to around 120 p.s.i.) That setting is maintain through out the wash period automatically if everything is working and their are no pressure leaks. (Routine maintenance to insure no hydraulic oil or air leaks is important) Usually with air cylinders one pressure for all rugs is sufficient. Inherit to the hydraulics, you generally have to back off the pressure to a lower setting when doing the big fat funky rugs. Why? When the really thick rug passes out the roller, you will have an abrupt closure of the two rollers creating a sudden noise due to collision. With the air cylinders, it is less of an issue since air cylinders minimizes the abrupt slamming together of the rollers in these situations.
3. Wringers can allow faster production. However, centrifuges are
superior for getting the water out better and leaving a softer hand on the pile with less post cleaning work on fringes. It is optimum to have both working one after the other in rug processing.
4. In my opinion I believe there is a misnomer about dye bleed and which device is better. I would submit: Manage the dye migration before putting the rug through either device. You can tattoo a rug with migrating dyes in a spinning centrifuge if the loose dyes are not remedied beforehand. Dye bleed can spread through a rug if not managed before putting it through the wringer too.
