How Servo Sheeters Improve Efficiency of Printed Material Output

The following blog serves as the second article in a two-part series focusing on how servo technology has improved web press operations.

In order to find a solution to the obstacles associated with mechanical sheeters, servo technology is now being used to improve sheeter flexibility. Servo driven sheeters do not have to be connected to a lineshaft, allowing a user to easily alter cut lengths or create unusual, custom-cut lengths without having to detach the sheeter from the press and perform manual modifications.

Vits America, Inc. is a leading supplier of variable repeat sheeting systems for the printing, packaging, and converting industries. With their Vits model L.P. or H.P. sheeters, the company uses servo technology to improve sheeter flexibility. "The shaftless sheeter gives you the opportunity to have mobility. You can move the sheeter from one press to another, something that was impossible with a lineshaft-connected machine,” states Robert Morelli, former sales director of Vits America. "And with servo control, make-ready time is dramatically cut. We can change cut lengths in a few minutes.” The servo sheeters also increase cutting accuracy by lowering feed rates. And by replacing the number of parts needed by mechanical sheeters, servo sheeters only cost a few percent more than their predecessors.

To demonstrate the power of this new servo driven technology, Vits America sold their first two servo sheeters to a company in China that possesses ten web presses. Using this new technology, the company is now able to take a roll off the press and cut it off-line, rather than buying individual sheeters for each press. Servo sheeters have met with such extreme customer satisfaction, Robert Morelli firmly believes that the digital sheeter will likely supplant its mechanical ancestor in the near future.
