John, the Svecia's were ultra reliable & never broke down as they are so well designed. Some similar looking machines used to go wrong big time & a couple of the copies I worked on had a tendency for a nut & bolt to drop off the vacum unit piston & straight into the casing where the fan was. On each occasion when we took the fan casing apart you would find all the small fan blades in a pile at the bottom

I used to then put a piece of mesh over the opening to stop it happening again which it did.
The problem we had with the fully automatic Svecia cylinder press was the fork lift driver. On a few occasions he backed the fork lift into the auto stacker at the end of the machine & this meant it moved backwards towards the driers. The belts of the auto stacker would then rub against the driers belt & make go into reverse which, meant that all the material in the drier would then start heading back to the printer very quickly. You can imagine the mess it made & it usually meant a ripped screen & ink everywhere. I have to admit the first time it happend we were all scratching our heads why the drier suddenly went into reverse.
