What to do when your belt is too loose?
First, move the tail pulley. It can be moved to "take-up" the belt stretch.
When the take-up screws are still all the way out and the belt still stretches, what can you do next?
Longer conveyors are provided with one or more short pieces of belt added, called a "Dutchman". Remove the short pieces of belt. Now you can start the "take-up" procedure all over again.
If a "Dutchman" was not provided, you may need to add an underside take-up to your conveyor.
There is more belt stretch on a long, long conveyor than the regular take-up and Dutchman will give. So an "Underside Take-Up" should also be used.
When should I use underside take-up?
