Back in the 70's, i seem to recall a tv ad for a Creda washing machine that spun in one direction, stopped and spun in the other direction. Magnus Pike, as i recall was "demonstrating" it..or did i imagine it?
I recall that advert. It was the rhythm spin and was supposed to reduce creasing. I knew a woman who had one. Not sure if it span in different directions. It spun for a few seconds then tumbled and each spin phase got faster and longer until it was at full speed.
It had a setting to bypass the rhythm spin as it added a good extra 10 mins to the final spin cycle. Was A nice machine. I was always a bit jealous as we only had a crappy Hoover twin tub.
Is something now most all modern European and North American h-axis washers do as a matter of course.
Older washers such as my Miele W1070 had a series of "graduated pulse spins" which served pretty much same purpose among other things. Prevents hard creases from laundry being plastered against drum at once after rinsing.
These short or reverse spins allow washing to fluff and redistribute itself which in theory should make for more balanced final spin as well.
If you ever used a spin dryer (twin tub or stand alone), you'll often notice while washing does emerge spun dry, it can also look dreadful.
