Batting is a process in which a composite baseball or softball bat is placed in a batting machine between plastic rollers in order to quickly break the bat. The rollers squeeze the bat at increased but controlled compression increments and then the bat rotates 20 to 25 revolutions for each increment. They work the same way as an old doorbell washer from the 1890s. I like to say that the wringer washer was the original bat laminating machine.
Once a bat is broken, it will hit one more ball. There are scientific studies that state that the speed of the ball leaving the bat increases by several miles per hour. It is a simple conclusion that speed translates into distance. In the game of baseball, extra distance translates to base hits or even home runs over the fence.
How does this work?
Composite bats are made of carbon fiber materials and special resins. When new, the bat is stiff and does not reach its full potential. Once the resins break down between the fibers of the carbon fibers, the bat will have a springboard or springboard effect to that area.
This happens naturally over time when the bat hits the ball. After 500 to 1500 solid hits, the bats will begin to reach their full potential.
A perpendicular bat rolling machine is a machine in which the bat is inserted into the rollers at a 90 degree angle to the machine. He then moves the bat back and forth, usually with a drive roll. Compress the bat in increments, removing the bat each time and twisting the barrel and then reinserting it and applying the same pressure. You must roll at least 8 points of the barrel in each increment, which means that you must remove the bat a minimum of 4 times and turn. If you compress at 4 increasing levels of compression, it will have been readjusted 16 times.
A perpendicular machine will roll your bats, but you need to be careful as you may end up leaving flat spots at the sweet spot of the bat.
If you are not going to roll a lot of bats, then a perpendicular machine will serve you well.
A parallel bat laminating machine is a machine that typically has 2 or 3 rollers. The barrel of the bat is placed in the machine in the same plane as the rollers. It then compresses again in larger increments and then spins the bat with a drive roll for 20 to 25 revolutions. You will not need to remove the bat when rolling parallel. The downside to rolling only in parallel is that you are breaking a larger section of the bat at a time.
So what are the hitters saying?
Bat swinging has progressed to near perfection. The best rollers in the industry roll bats both ways. They will roll perpendicularly first, but will only roll between 50 and 75 percent of maximum rolling pressures. Again, they will do this in larger increments. They will then roll the bat in parallel, starting with the lowest pressure and rolling for 20 to 25 revolutions. They will increase the pressures in increments of 3 to 4 and repeat the revolutions. They will continue this process until they reach maximum pressure for the bat.
By rolling both ways, you will get the best spin out of your bat and you won’t have to worry about dead spots or breaking too large an area at once. It is very important that you choose a parallel machine that can roll in both directions. By being able to roll both ways, you will be able to maximize the breaking potential of your bats quickly and easily.
