For some of our older viewers, you may remember a toy called Shrinky Dinks. This was a toy where you would color in on a plastic sheet, and then you would cut it out and put it in the oven and it would shrink. So something that was four inches went down to maybe two inches or the size of a key chain. This same technology is involved in stretch belts. If you see a belt that says stretch or stretchy on the side, or it's indicated on the product sleeve that it is a stretch belt. Well, this belt, it typically doesn't have a tensioner with no tension. How does it set that final tension? Well, it uses that same properties as shrink heatings. When the belt is run and gotten up to temperature, it actually conforms to the pulley and grooves to give the proper tension. So what does that mean to you, the technician?
