48 THE AUSTRALIAN NATIONAL DRYCLEANER & LAUNDERER, APRIL/MAY/JUNE 2009 Dear Doctor, I have a large diameter ironer about 10 years old I have noticed lighter coloured patches ovalish in shape in the felt on different areas of the roller. What is caus- ing this, should I be concerned? Crop Circles Dear Crop Circles, it sounds that some areas of your roll are not making contact or maintaining an even pressure on the bed. These hollow areas are not in contact with the hot bed of the ironer so they are comparatively cool. I would investi- gate further to see if an area of dam- aged or crushed springs exists. Springs may be missing or have lost their elasticity. I have, however, seen a couple of cases where the roll itself has been crushed and has become ‘unround’ causing high and low points. Is the roll is dented or damaged in any way? The Doctor Dear Doctor, I have an older model 3 roll 800 Braun Ironer. In the past months I have noticed that the middle roll is “rocking” in the bed. Initially I thought that the roll was under- size, but the problem persisted after we changed the felt. The ironing quality is not bad, but we sometimes get pinch marks on the linen, what can you suggest what we look at next? Older Rocker Dear Older Rocker, this was an interesting problem, normally there would be only slight, if any movement in the roll. With the rolls raising and lowering they would be secured with guides so that the roll would seat it’s self correctly when in contact with the bed. I would suggest that you check whether the guides for the roll have loosened; it may also be worthwhile checking the bearings on the roll to see if those have worn. Good luck, let me know how you get on with this curly one! The Doctor (See update comment and photo!) Dear Doctor, I have an ironer, the type that has large drying belts around a heated cylinder. I have noticed that recently it is not heating up as fast as it used to. I don’t understand why this would be. Do you have any pointers what to look for? Cooling Off Dear Cooling Off, this is quite a common problem on this type of ironer. At the front under- neath in the centre is the temperature sensor attached to the drum. It’s very important that you check this is cleaned regularly, ideally with an air gun. If lint builds up on the sensor it insulates itself and sends a false tem- perature reading to the computer. If cleaning it doesn’t work the probe or thermostat may be faulty or alternatively the burners are not burning correctly. Or it may be being starved of gas. Get a plumber to check with a manometer, good luck. The Doctor THE IRONER DOCTOR Resolving common problems with ironers Following the correspondence with “Older Rocker” a photograph of the offending bearing was taken; it had obviously been wearing for some considerable time.
