Re: SER1 Flat belt drives

[prev] [thread] [next] [Date index for 2004/10/20]

Many years ago I worked with the thrashing contractors when they came
round the villages in the UK and as I remember the twist was just to
change the rotation to what was required from the driving unit.

I was told that the twist was what helped to keep it centered and it 
stopped a long belt that was sagging from rubbing, if the bottom bit was

being pulled by the drive pulley this would be taught and the top would
sag 
down and touch it thus wearing the belt. So I just assumed that they all

had a twist put in them short or long.
