This picture of the Rinse Section itself shows a number of changes we've made. In order to reduce the number of parts you have to keep on hand, we've changed the Roller Lever Arms (also known as "pork chops") to use the same bearings as the long rollers of the drying section. Older machines used a variety of bearings, all unique to this section of the machine.
We still use the same seals and cover plates, of course, along with the highly reliable "white" pressure rollers we introduced over 17 years ago.
Another change, first introduced with the Mk. 5, is a "slotted" side frame. On the original Mk.3 and Mk.4, you had to remove the bearings from a roller before it could be removed. This could be a real problem if the bearing was frozen on the shaft. However, the slots allow you to remove and replace the rollers and bearings as an assembly, and do the rest on your shop bench, where you have more tools available.
We've also added something - reinforcing bars, which eliminate the flexing and cracking of the side walls. Ever had a pressure roller pop out of its bearings, as the lever flexed outward? These bars, along with plates that go on both sides of the roller lever pivot, eliminate that problem.
The final major change is to get rid of the gravity-feed rinse water feed, as well as the "recycling channels". We now feed hot rinse water directly to spray jets, similar in design to the ones used in the wash section, which serve dual functions - they are sized to meter the water going into the machine, and they provide more impact to remove the soap better.
We do not have exact numbers on improvements in soap removal over the previous methods at this time, but we hope to have this information soon.
The water is still recycled - it goes into the wash tank as "make up" for what is dried out of the towels - but all the rinses now use clean water, for better soap removal.
Oh, and lest we forget, the pressure cylinders are now controlled by a separate manual release valve, to keep tension on the towel at all times, except when necessary to fix a broken towel...
