When rolling a bat, it’s placed between two/three rollers of a Bat Rolling Machine and then pressure is applied to the rollers like a vice. As the bat passes through the rollers the bats fibers are stretched out and the glue holding the layers together is broken down. The is the same thing that happens as you take hours of batting practice. This causes the fibers to become more flexible which greatly improves the bat’s trampoline effect. This trampoline effect is what produces the batted ball speed and distance. It will also widen the sweet spot of the bat which will make you a more consistent hitter.

Types of Bat Rolling Machines

There are 2 types of Bat Rolling Machines that are currently being used. Those types are Perpendicular and Parallel. Perpendicular Bat Roller roll your bat perpendicular to the barrel and the Parallel rollers roll parallel to the barrel. The perpendicular type is the preferred method of rolling. Bats are designed to be compressed in small areas similar to hitting a ball. Parallel rolling machines allow you to roll the entire barrel all at once. The only benefit to doing this is to be able to roll your bat faster. It is NOT recommended to roll via the parallel method as it MAY too much stress on the barrel of the bat if not performed by an experienced company. It’s recommended that you find a company that offers multiple options of which bat rolling method is used on your bat. This ensures they have the needed experience to give you the desired results without potentially damaging your bat.
