Laminating Rollers...can someone explain to me...

Can someone explain to me the purpose of a laminating roller? How do you use it and what are the best practices?

Thanks!

I think you’re referring to the ribbed rollers? It helps saturate the resin for a better wetout. I guess you just run it accross the fabric with moderate pressure. It also helps push the excess resin off of your working surface. I don’t use it but it’s just a matter of time before I order one.
